In a new study, scientists from NOAA, University of South Florida, Florida International University, University of Miami, and LGL Ecological Associates, compared wind information alongside Sargassum Inundation Risk (SIR) maps against citizen science reports of inundation in the coasts of Florida, Gulf of Mexico, Bahamas, and Caribbean regions. With present SIR maps, inundation is considered as more likely if large densities of satellite-detected Sargassum are near a coast. The scientists in the study found that shoreward wind velocity used in conjunction with SIR indicators greatly improves the agreement with coastal observations of Sargassum beaching compared to SIR indicators alone. Including wind metrics in SIR maps will allow for improved understanding of Sargassum trajectories in coastal areas for forecast purposes.

A marine heatwave has spread across the Gulf of Mexico and the Caribbean with temperatures ranging between one and three degrees Celsius (~2-4.5˚F) above average. Ocean temperatures around south Florida are the warmest on record for the month of July (dating back to 1981). Marine heatwaves are not unprecedented, but their influence on tropical storm development and coral reef health, as well as the persistence of the current heatwave, are among the causes for concern.

There is more to the job of a Hurricane Hunter than meets the eye. Researchers and pilots from the National Oceanic and Atmospheric Administration (NOAA) bravely fly into one of the most dangerous environments on Earth to collect data inside a tropical cyclone, which helps to improve forecast models and protect lives and property.

A very large amount of orange/brown seaweed (sargassum) washed up on the coastline.

When massive mounds of golden-brown seaweed began piling up on beaches throughout the Caribbean and West Africa in summer of 2011, the question of where it came from probably mattered less to residents and businesses than how they were going to get rid of it. Certainly, few would have connected the Sargassum seaweed invasion to the extremely snowy 2010-11 winter in the eastern United States. But according to a hypothesis proposed by a team of NOAA AOML-led scientists in 2020, the two phenomena share an origin story: an extremely strong and long-lasting shift of the North Atlantic Oscillation into its negative phase back in 2010.

Earlier this year, ocean scientists raised an alert about the large amount of seaweed drifting in the tropical Atlantic this spring. Experts warned that the region’s annual spring bloom of Sargassum—a free-floating brown macroalgae from the North Atlantic that suddenly appeared in large quantities in the tropics in 2011— was the densest observed in March since scientists began tracking the phenomenon with satellite images twenty years ago. Excessive amounts of Sargassum raise the chances that large mats will break free from the prevailing currents and wash ashore later this spring and summer in the Caribbean, Gulf of Mexico, and around Florida.

In honor of Women’s History Month, NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) would like to recognize two of our female leaders within the Hurricane Research Division (HRD), Heather Holbach and Shirley Murillo. We talked to these incredible scientists to learn more about their leadership roles within the division and to seek out any advice they have for women early in their science career.

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) have shown that the Global Meridional Overturning Circulation (GMOC), commonly known as the global ocean conveyor belt, has changed significantly in the Southern Ocean since the mid-1970s, with a broadening and strengthening of the upper overturning cell and a contraction and weakening of the lower cell. These changes are attributed to human induced ozone depletion in the Southern Hemisphere stratosphere and increased carbon dioxide in the atmosphere. The study also shows that the changes in the Southern Ocean are slowly advancing into the South Atlantic and Indo-Pacific oceans.

The ability to predict whether and when a tropical cyclone will become vertically aligned is critical for intensity change forecasts, as storms can intensify quickly after achieving an aligned structure. A recent study from researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory and the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies shows how weak, disorganized tropical cyclones containing different center locations with height, called misalignment, can develop a vertically aligned structure. This study works to improve forecasts of when this alignment might occur by identifying key times of the day and other tropical cyclone characteristics when alignment is likely.

The amount of wind shear, i.e., the change of the wind with height, is one of the most commonly used predictors of tropical cyclone intensity change, with large amounts of wind shear generally being unfavorable for intensification. Regardless of the direction of the wind shear, tropical cyclones in the North Atlantic basin usually have warm, moist air from the environment near the sea surface on their east side (solid red arrows in the images) and cool, dry air from the environment on their west side (solid blue arrows in images).

Two large orange saildrones in the calm ocean.

For the first time ever, Saildrone Inc. and NOAA have used an uncrewed surface vehicle to collect oceanic and atmospheric data from inside the eye of a hurricane. On September 30th, 2021 saildrone 1045 travelled directly into Category 4 Hurricane Sam.

Saildrone Inc. and the NOAA have released the first video footage gathered by an uncrewed surface vehicle (USV) from inside a major hurricane barreling across the Atlantic Ocean.

The Saildrone Explorer SD 1045 was directed into the midst of Hurricane Sam, a category 4 hurricane, which is currently on a path that fortunately will miss the U.S. east coast.  SD1045 is battling 50 foot waves and winds of over 120 mph to collect critical scientific data and, in the process, is giving us a completely new view of one of earth’s most destructive forces.

It can be hard to stay upbeat as a marine biologist, especially with the onslaught of existential threats like climate change facing the planet. Coral reefs are arguably the ecosystem that stands to lose the most with respect to climate change, namely because the resident organisms are highly sensitive to elevated temperatures. Furthermore, the limestone-based reef framework itself is diminishing before our eyes due to the accompanying  rise in carbon dioxide levels (which decreases oceanic pH, leading to ocean acidification). That being said, there are corals out there that display resilience, continuing to thrive in habitats that would appear decidedly marginalized to even the untrained eye.

In a recent study published in AGU’s Journal of Geophysical Research – Oceans, scientists at AOML identified key ocean features that supported the rapid intensification of Hurricane Michael (2018), despite unfavorable atmospheric conditions for development. The study demonstrates the importance of using realistic ocean conditions for coupled (ocean-atmosphere) hurricane models in order to achieve the most accurate hurricane intensity forecasts.

A large orange/red saildrone floats in the ocean

Saildrone is announcing a new mission to deploy five uncrewed surface vehicles (USVs) from the US Virgin Islands in August to gather key data throughout the 2021 Tropical Atlantic hurricane season. The USVs will be equipped with specially designed “hurricane wings” to enable them to operate in extreme conditions. Saildrones are the only USVs capable of collecting this data and are designed to withstand winds over 70 mph and waves over 10 feet, which occur during a hurricane weather system. The five saildrones will sail into the paths of hurricanes to provide valuable real-time observations for numerical hurricane prediction models and to collect new insights into how these large and destructive weather cells grow and intensify.

Scientists at AOML are preparing for the active anticipated 2021 Atlantic hurricane season with the introduction of new observation tools, modeling techniques, and field campaigns to improve hurricane intensity and track forecasts.

A phytoplankton bloom in the Atlantic Ocean. May 2016

Phytoplankton drifting near the ocean surface play a critical role in marine biogeochemistry, carbon cycling, and ecosystem health. But measuring the activity of these microscopic organisms is challenging. Although scientists rely on ship-based sampling and satellites to quantify their abundance, both methods have limitations. In a study published recently in the Journal of Geophysical Research-Biogeosciences,* Argo profiling floats equipped with biogeochemical sensors, i.e., BGC Argo floats, were used to obtain the first year-long estimates of phytoplankton in the western North Atlantic Ocean.

Coral Outplanting. Image Credit: NOAA

A new study by researchers at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science and NOAA’s Atlantic Oceanographic and Meteorological Laboratory suggests that outplanting corals, specifically staghorn coral (Acropora cervicornis) from higher temperature waters to cooler waters, may be a better strategy to help corals recover from certain stressors. The researchers found that corals from reefs with higher average water temperatures showed greater healing than corals from cooler waters when exposed to heat stress.

To help improve the long term survival of nursery raised staghorn coral (Acropora cervicornis), Ruben van Hooidonk, a coral scientist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory and the Cooperative Institute for Marine and Atmospheric Studies has developed a new experimental mapping tool i that ranks suitable outplant locations. There are currently at least seven coral nurseries in Florida that cultivate staghorn coral,  representing one of the best opportunities to maintain resilient populations of this species.

In absorbing carbon dioxide (CO2), the oceans play a crucial role in regulating the climate, a role yet to be fully understood. However, the oceans’ ability to contribute to climate regulation may decline and even be reversed in the future. The oceans that are now the blue lungs of our planet, could end up contributing to global warming.

In a recent article published in the Journal of Geophysical Research - Oceans, scientists at AOML evaluate the variability of the heat transport in the South Atlantic by developing a new method to measure its changes on a daily basis.

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory are now focusing on what happens where the sea meets the atmosphere to help solve the hurricane intensity problem. The place right above where the air meets the sea is called the planetary boundary layer. The ocean drives global weather. By building on past research, scientists have determined that factors in the boundary layer and underlying ocean such as salinity, temperature, currents, wave and wind patterns, precipitation, are crucial to understanding the energy that fuels a hurricane.

Scientists are heading to sea on the R/V Walton Smith to sample areas where red tide blooms are commonly present off the west Florida coast. Karenia brevis, the organism that causes red tide, forms blooms when elevated concentrations (>100,000 cells per liter) are present in the water. K. brevis produces toxins called brevetoxins that can cause massive fish kills, weaken or kill marine mammals, and (if the toxin becomes aerosolized and inhaled) cause respiratory distress in humans and marine mammals. The team of scientists will be comprehensively sampling a series of transects along the West Florida Shelf.

On December 11, 2020 researchers with the Global Carbon Project released their annual update for the Global Carbon Budget. Daily global CO2 emissions are estimated to have decreased by a maximum of about 17% by early April 2020 compared to average levels in 2019. About half of this change is due to changes in surface transport, especially road transport, during the COVID-19 pandemic.

Despite their differences, it is still widely thought that Atlantic Niño is analogous to El Niño in many ways. Specifically, the atmosphere-ocean feedback responsible for the onset of Atlantic Niño is believed to be similar to that of El Niño, a process known as Bjerknes feedback. The near-surface trade winds blow steadily from east to west along the equator. When weaker-than-normal trade winds develop in the western Atlantic basin, downwelling equatorial Kelvin waves propagate to the eastern basin, deepening the thermocline and making it harder for the colder, deeper water to affect the surface.

In a recently published study, AOML hurricane researchers used multiple computer model forecasts to gain a better understanding of how Hurricane Michael, which made landfall in the panhandle of Florida with winds up to 162 mph, rapidly intensified despite strong upper-level wind shear which usually weakens hurricanes. By contrasting two sets of forecasts, the study found that Michael only rapidly intensified when rainfall completely surrounded Michael’s center, and when the eye of the storm itself was located in nearly the same place at different heights.

NOAA is turning 50!  The federal science agency that provides daily weather forecasts, severe storm warnings, fisheries management, and coastal restoration, is celebrating by opening its doors to the south Florida community with a free open house on April 25th, 2020 from 10:00 a.m to 3:00 p.m.  What better way to celebrate Earth Day than seeing science in action with friends and family!

TACOS has added 10 acoustic current meters to the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) buoy, moored at 4N, 23W.  Profile measurements are taken every 1-10 minutes, depending on depth.  Prior to the addition of the TACOS upper ocean observations in March 6, 2017 velocity profiles were only collected at this location during shipboard surveys.  These measurements are important because ocean currents influence temperature, salinity, and air-sea fluxes in the tropical North Atlantic, which affect weather, climate, and fisheries of the surrounding continents.

Every year the Global Carbon Project publishes an authoritative observation based Global Carbon Budget detailing the annual release of fossil fuel carbon dioxide and the uptake by the terrestrial biosphere and oceans. In 2018 the global carbon emissions were still increasing, but their rate of increase had slowed. Global carbon emissions are set to grow more slowly in 2019, with a decline in coal burning offset by strong growth in natural gas use worldwide.

Diagram that shows the interactions, exchange, and circulation of carbon dioxide within the ocean, identifying where satellite-based Earth observations are likely to play a leading role in expanding understanding and capability: (1) atmospheric measurements at the ocean surface; (2) quantifying gas, momentum, and heat atmosphere–ocean exchange processes; (3) capturing near-surface gradients in the water; and (4) measuring internal circulation and surface transport. Image from Frontiers in Ecology and the Environment.

The ability to predict Earth’s future climate relies upon monitoring efforts to determine the fate of carbon dioxide emissions. For example, how much carbon stays in the atmosphere or becomes stored in the oceans or on land? The oceans in particular have helped to slow climate change as they absorb and then store carbon dioxide for thousands of years.

AOML’s hurricane scientists and friends celebrated the last regularly scheduled tropical weather discussion of the year on October 18.

November 19 – 21, 2019, AOML hosted a three day external review to evaluate the quality, performance, and relevance of our research portfolio. NOAA’s Office of Oceanic and Atmospheric Research conducts these reviews every five years to gauge the effectiveness of the research portfolios of all the labs, and also to forge new partnerships for research and collaborations across NOAA. Feedback received after the completion of the lab review will help set new priorities for AOML. The 2019 AOML review featured presentations from each science division, lightning talks from scientists, a poster session, lab tours, and an early career luncheon. We also had the pleasure of hosting Deputy NOAA Administrator Rear Admiral Tim Gallaudet at the opening of the review. 

The most dangerous part of the hurricane is the eyewall close to the ocean. It’s where the storm draws energy from heat in the water, which influences how strong - and how quickly - the storm will develop. It’s also where the strongest winds lurk.Direct and continuous observations of the lower eye-wall would help forecasters understand critical information about the storm’s development. NOAA P-3 “Hurricane Hunters” routinely fly through hurricane eyewalls to gather storm data, but avoid flying close to the ocean because conditions are too hazardous.

AOML researchers have taken an innovative approach to studying the changing carbonate chemistry of seawater at shallow coral reef sites. Using 3D printing technology made possible by the new Advanced Manufacturing and Design Lab at AOML, researchers with the Acidification, Climate, and Coral Reef Ecosystems Team, or ACCRETE, have created a water sampler in-house.

Sea Level Feedback on AMOC

The global mean sea level rise caused by ocean warming and glacier melting over landforms such as Greenland is one of the most alarming aspects of a shifting global climate. However, the dynamics of the ocean and atmosphere further influence sea level changes region by region and over time. For example, along the U.S. East Coast, a pronounced acceleration of sea level rise in 2010-2015 was observed south of Cape Hatteras, while a deceleration occurred up North.  These patterns provide background conditions, on top of which shorter-period (and often stronger) weather-driven sea level fluctuations compound what coastal communities directly experience day by day. Therefore, to develop or improve regional sea level predictions, it’s important to identify these patterns and explore how they change over time.

The new research published by NOAA and international partners in Science finds as carbon dioxide emissions have increased in the atmosphere, the ocean has absorbed a greater volume of emissions. Though the volume of carbon dioxide going into the ocean is increasing, the percentage of emissions — about 31 percent — absorbed by it has remained relatively stable when compared to the first survey of carbon in the global ocean published in 2004.

Hurricane Lane's Stadium Eyewall Effect shows clouds surrounding the P3 against a stark blue sky.

AOML hurricane researchers supported nearly all of the 50 missions NOAA’s Hurricane Hunter aircraft flew into eight tropical systems in 2018’s hurricane season, collecting data to help improve forecasts for future storms. The final flight into Hurricane Lane would make history for several reasons. Hurricane Lane was part of NOAA’s first hurricane deployment out of Hawaii, and one of those flights was led by the first all-female science crew on the flying laboratory. For Women’s History Month, we are proud to highlight this milestone and recognize the members of the first all-female science crew on a hurricane flight.

Ocean tracers such as heat, salt and carbon are perpetually carried by the global meridional overturning circulation (GMOC) and redistributed between hemispheres and across ocean basins from their source regions. The GMOC is therefore a crucial component of the global heat, salt and carbon balances.

AOML recently led a multi-agency (NOAA/AOML, NOAA/SEFSC, State of Florida Fish and Wildlife Research Institute, Florida Fish and Wildlife Commission, NOAA/NESDIS, University of South Florida, MOTE Marine Laboratory and Aquarium, and University of Miami) research cruise to study the effects of Southwest Florida’s ongoing red tide. To address such a complex problem as red tide, the cruise brought together a diverse team of experts consisting of commercial fishermen, oceanographers, systems ecologist, phytoplankton ecologist, and fish population biologist. This cruise allowed researchers to take a holistic approach to characterize the extent of the red tide and its impacts. The goal of the cruise was to understand why these blooms happen to better inform effective future response measures and hopefully improve Florida’s resilience to these coastal events. 

Beach at Sunrise

Few accessible places represent Earth’s natural beauty quite like our beaches, but looks can be deceiving if there is a bacterial outbreak or contamination from offshore activities. Not being able to see these contaminants puts families at risk of exposure if they aren’t properly warned. The BEACHES project (Beach Exposure And Child Health Study), a collaboration between the University of Miami’s College of Engineering and the Cooperative Institute for Marine and Atmospheric Studies and AOML, along with the Universities of Arkansas and Texas, aims to pair child behavioral science with microbiology to address exposure risk of beachgoers.

 In August 2018, a team of biological oceanographers and ecologists set sail on the R/V Walton Smith to sample the waters of Biscayne Bay & Florida Bay. AOML has conducted regular interdisciplinary observations of south Florida coastal waters since the early 1990’s. We spoke with Chris Keble, the lead scientist for AOML’s South Florida Ecosystem Restoration Research project, to learn more.

Ubaldo Lopez of the University of Puerto Rico at Mayaguez prepares to launch NOAA ocean gliders in the summer of 2017 off Puerto Rico.

NOAA will soon launch a fleet of 15 unmanned gliders in the Caribbean Sea and tropical Atlantic Ocean this hurricane season to collect important oceanic data that could prove useful to forecasters. “If you want to improve prediction of how hurricanes gain strength or weaken as they travel over the ocean, it’s critical to take the ocean’s temperature and measure how salty it is,” said Gustavo Goni, an oceanographer at NOAA’s Atlantic Oceanographic and Meteorological Laboratory who is helping lead the glider research. “Not just at the surface, which we measure with satellites, but down into deeper layers of ocean waters.”

AOML researchers recently participated in the South Florida Ecosystem Restoration Research Cruise, a survey of south Florida’s coastal waters on June 22-26 aboard the R/V Savannah. These cruises have investigated coastal water quality in south Florida since the late 1990s. The science crew collected samples to measure nutrients, plankton, productivity, chlorophyll a, and dissolved inorganic carbon. They also recorded salinity and temperature to help monitor ecosystem restoration efforts in south Florida. These cruises have an additional focus on lower trophic level dynamics downstream from the Shark River on the southwest Florida shelf.

Florida Coral Disease April 2018

NOAA contributed to a study published today in the journal Nature that compares the upward growth rates of coral reefs with predicted rates of sea-level rise and found many reefs would be submerged in water so deep it will hamper their growth and survival. The study was done by an international team of scientists led by the University of Exeter in the United Kingdom.

NOAA Ship Ronald H. Brown continues to make its way around the world deploying many devices to observe the ocean. These platforms measure temperature, salinity, and ocean currents. This creates a network of ocean data that can be used to understand its physical dynamics and help us understand and anticipate change in weather, climate, and even ecosystems.

Argo Deployment 2017

Staff with the US Argo Data Acquisition Center (DAC) at AOML marked an important milestone this past February by processing the one millionth profile from Argo floats. The DAC team has been processing and quality controlling all of the raw data obtained from US-deployed Argo floats since 2001, with about 90,000 temperature-salinity profiles processed annually since 2007. These profiles have provided the global scientific community with an unprecedented record of the evolving state of the upper ocean, advancing understanding of the ocean’s role in world climate.

Below the surface of our ocean there is another, smaller world that moves fast and breathes in and out with the ocean. Zooplankton communities likely create the fastest source of sinking carbon to the deeper ocean, and studying this process can help us understand more about the carbon cycle and how it affects us. Victoria Coles, Scientist aboard the NOAA Ship Ronald H. Brown, can tell you more in her post “Biome Beneath the Surface.”

Cheeca Moasaic Comparison

A recent study by AOML and partners identified coral communities at Cheeca Rocks in the Florida Keys National Marine Sanctuary that appear to be more resilient than other nearby reefs to coral bleaching after back to back record breaking hot summers in 2014 and 2015 and increasingly warmer waters. This local case study provides a small, tempered degree of optimism that some Caribbean coral communities may be able to acclimate to warming waters.

AOML scientists, Hosmay Lopez and his colleagues used observations as well as model simulations of 20th Century climate and 21st Century projections to show that the occurrence of heat waves in the U.S. are on the rise and will continue to do so in the coming decades. This research was recently published in Nature Climate Change.

Existing observations show that Indian Ocean surface water temperatures have been increasing since the 1970’s. But has the deep ocean warmed? Have the regional concentrations of dissolved oxygen, carbon dioxide, or nutrients changed? Has the western Indian Ocean become more acidic? These and more questions will be addressed by scientists after the completion of this cruise.

Surface drifter being deployed. Image credit: NOAA

Researchers from AOML’s Physical Oceanography Division recently deployed three surface drifters and ten special spot trace drift buoys, all contributed by NOAA, in the Caribbean Sea to help to identify the site of where an Argentine Air Force C-54E Skymaster aircraft crashed in 1965. The data gathered by the drifters will help back track the possible location of the lost aircraft based on the location of life vests recovered during search operations after the crash. These deployments are part of a larger effort in support of the Argentine Air Force and search and rescue operations professionals from the US, Costa Rica, Panama and Argentina to locate the remains of the flights. Mr. Jose Rivera of NOAA, Captain Marcelo Covelli from Perfectura Naval Argentina and Licenciado Mariano Torres Garcia, representing the Argentine Air Force, are closely coordinating the 4th Expedition in the Caribbean Sea to locate the remains of TC48 and its 68 crew members on April 2018.

Climate projections for the twenty-first century suggest an increase in the occurrence of heat waves. However, the time at which externally forced signals of anthropogenic climate change (ACC) emerge against background natural variability (time of emergence (ToE)) has been challenging to quantify, which makes future heat-wave projections uncertain. In a new article published in Nature Climate Change (Lopez et al., 2018), Hosmay Lopez and his team combine observations and model simulations under present and future forcing to assess how internal variability and ACC modulate US heat waves.

A new analysis of heat wave patterns appearing in Nature Climate Change focuses on four regions of the United States where human-caused climate change will ultimately overtake natural variability as the main driver of heat waves. Climate change will drive more frequent and extreme summer heat waves in the Western United States by late 2020’s, the Great Lakes region by mid 2030’s, and in the northern and southern Plains by 2050’s and 2070’s, respectively.

“These are the years that climate change outweighs natural variability as the cause of heat waves in these regions,” said Hosmay Lopez, a meteorologist at NOAA’s Atlantic Oceanographic Meteorological Laboratory and the University of Miami’s Rosenstiel School Cooperative Institute for Marine and Atmospheric Studies and lead author of the study. “Without human influence, half of the extreme heat waves projected to occur in the future wouldn’t happen.”

This year, the children partook in lessons and activities in the subjects of buoyancy, density, ocean currents and circulation, marine debris, ecosystem based management, and ocean observations.

CARICOOS Team

Scientists strategically deployed the gliders during the peak of hurricane season, from July through November 2017, collecting data in regions where hurricanes commonly travel and intensify. The gliders continually gathered temperature and salinity profile data, generating more than 4,000 profiles to enhance scientific understanding of the air-sea interaction processes that drive hurricane intensification.

AOML scientists recently returned from the first cruise of 2018. As part of the South Florida Project, regional surveys over the southwest Florida shelf and the Florida Keys reef tract are routinely performed aboard the R/V F.G. Walton Smith on a bimonthly basis, to keep a watchful eye over sensitive marine habitats found in the region. Sampling methodologies include discrete sampling and flow through measurements of water quality and chemistry, and biological oceanographic parameters.

Researchers at AOML, NESDIS CoastWatch, and the University of Miami are currently exploring how the distribution of marine debris is affected by both ocean currents and wind. During a recent experiment, scientists deployed several prototype drifters in the Florida Current off the coast of Miami to simulate commonly found debris of varying weights and shapes. These drifters carry GPS transmitters that provide their location four times per day.

PIRATA Array

Researchers at NOAA AOML have released a new tropical Atlantic data set that includes several enhancements to improve data accuracy and data collection in the tropical Atlantic. The new data set is called enhanced PIRATA, or ePIRATA, and provides continuous records of upper-ocean temperature, salinity, and currents, together with meteorological data such as winds, humidity, and solar radiation. ePIRATA should prove valuable in better analyzing ocean and atmospheric processes in the tropical Atlantic.

PIRATA, the Prediction and Research Moored Array in the Tropical Atlantic, is a multinational observation network, established to improve knowledge and understanding of ocean-atmosphere variability in the tropical Atlantic. It is a joint project of Brazil, France and the United States of America, motivated by fundamental scientific issues and by societal needs for improved prediction of climate variability and its impact on the countries surrounding the tropical Atlantic basin. PIRATA provides measurements at 18 locations throughout the tropical Atlantic

There have been many efforts to understand the role of the Atlantic Meridional Overturning Circulation (AMOC) as a potential predictor of decadal climate variability, motivated partly by its inherent relationship with North Atlantic sea surface temperature. In contrast, there is currently limited knowledge about the underlying mechanisms that govern the South Atlantic Meridional Overturning Circulation (SAMOC) variability and how it might feedback into climate, partly due to the small number of direct observations in this ocean basin.

Recent studies have suggested the possibility of the southern origin of the Atlantic MHT anomalies. These studies have used General Circulation Models (GCMs) to demonstrate covariability between the South Atlantic MOC (SAMOC) and the Southern Hemisphere westerlies at interannual to longer time scales. However, it has been pointed out that the sensitivity of the SAMOC to the changes in the Southern Hemisphere westerlies depends critically on the representation of mesoscale eddies in those models.

Loggerhead Sea Turtle Lost Years

The behavior and movement of sea turtles during their first few years at sea, known as the ‘lost years’, remains largely a mystery. Researchers from NOAA-AOML, NOAA Fisheries, University of Central Florida, and Projecto TAMAR recently collaborated on a study to explore the mechanisms of dispersal in Brazilian loggerhead turtles, to fill in some of these important early life history gaps. A previous study conducted in the Gulf of Mexico debunked the historic belief that young sea turtles rely solely on riding currents as a passive mechanism of dispersal. This latest study uncovers new drivers behind the travels of young sea turtles, suggesting there may be more of an ecological implication behind their behavior than previously realized.

In an effort to better understand our microbiomes, scientists from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) took part in a massive global research collaboration known as the Earth Microbiome Project (EMP), which recently released the first reference database, or atlas, of microbes covering the planet. This guide, released online in Nature today, will allow scientists to collaborate on studies and catalogue microbial diversity at an unprecedented scale.

2017's Active Hurricane Season

Over the past 20 years, improvements in hurricane computer modeling, observational instrumentation, and forecaster training have greatly increased forecast accuracy. The many complex interactions that occur within the atmosphere remain to be fully understood, especially at the small scales associated with tropical cyclones. However, these milestones mark critical advances in numerical weather prediction that are paving the way to the next generation of NOAA models. While hurricanes cannot be controlled, vulnerability to these complex storms can be reduced through preparedness. Early warning and improved accuracy of forecasts can help save lives and reduce property damages caused by hurricanes.

In a new study published in Environmental Health Perspectives, a team of scientists including researchers from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) explore the future risk of waterborne disease in a warming climate. Recently, the European Center for Disease Prevention and Control (ECDC) developed an interactive online tool that can be used to monitor coastal marine areas with environmental conditions favorable to Vibrio growth, aquatic bacteria that can cause human illness. The Vibrio Map Viewer is a real-time global model that uses daily updated remote sensing data to determine marine areas vulnerable to higher levels of Vibrio.

Orbicella faveolata

Coral scientists at NOAA’s Atlantic Oceanic and Meteorological Laboratory (AOML) are in the process of analyzing data that may shed light on the sub-lethal effects of sedimentation stress in coral larvae. Scientists recently conducted a series of lab experiments aimed at assessing the effects of Port of Miami dredge sediments on the larval performance of the Caribbean threatened coral Orbicella faveolata (also known as the mountainous star coral). Preliminary analysis suggests significant effects of sedimentation on both the survival and settlement of coral larvae.

Hurricane Aircraft

AOML is currently in the midst of a multi-year effort called the Intensity Forecasting Experiment (IFEX). IFEX aims to improve the understanding and prediction of intensity change by collecting observations from all stages of a tropical cyclone life cycle—genesis to decay—to enhance current observational models. By building on years of observational expertise and cutting-edge approaches to data integration and model development, hurricane scientists at AOML lead advancements in observations and modeling that have improved intensity forecasts by 20% in recent years.

Drop sonde

Observations of the atmosphere are critical to every aspect of weather forecasting. While there are several new and improved tools used to enhance storm forecasts, weather balloons prevail as one of the longest running and most dependable tools deployed by meteorologists. Released twice a day, every day of the year in the U.S. – sometimes more frequently during extreme weather events – weather balloons, also known as radiosondes, provide detailed and reliable data that ultimately help predict the path of storms.

Throughout the month of October, AOML scientists were hard at work surveying south Florida’s coastal waters. The research team focused on monitoring water quality, seagrass beds, and juvenile sport fish populations throughout Florida Bay, Biscayne Bay, Florida Keys and the southwest Florida shelf. These surveys assessed ocean temperatures, salinity, nutrients, environmental DNA and primary productivity to better understand how south Florida’s coastal ecosystems were impacted by the passage of Hurricane Irma.

The 2017 hurricane season has already fulfilled forecaster predictions of a busy year. Hurricane Harvey rapidly strengthened to a Category 4 hurricane before making landfall in Texas, late on August 25th.

Hurricane Andrew made landfall in Homestead, Florida, on August 24, 1992, with sustained wind speeds maxing out at 165 mph. This year marks the 25th anniversary of the storm, still one of the most catastrophic and costliest hurricanes in US History.

On August 21st, 2017, the entire nation celebrated a unique celestial event: the first total solar eclipse to cross the contiguous United States in 99 years.

Hurricane Andrew

Hurricane Andrew made landfall around 5 am in Homestead, Florida, on August 24, 1992, with sustained wind speeds maxing out at 165 mph. This year marks the 25th anniversary of the storm, still one of the most catastrophic hurricanes in US History. Andrew developed into a Category-5 hurricane in no more than 36 hours, roaring across south Florida and decimating the urban landscape in its wake. Not only did the storm reconfigure much of south Florida, causing an estimated $26.5 billion in direct damages in 1992, but it also led to a reconfiguration of the tools now used to study, forecast, prepare for, and respond to hurricanes. Many AOML staff members who lived in south Florida when the storm struck remain at the laboratory today, inspired by Hurricane Andrew to enhance the science behind forecasts and mitigate future damages from tropical cyclones.

Journal of Geophysical Research (JGR) Editors' Highlight

“Much of the work on the cause of Antarctic sea ice over recent decades has focused on atmospheric drivers but this paper focuses on the ocean’s role. The authors analyse the trend of Antarctic sea ice over the past 35 years on the basis of satellite data and model simulations forced with atmospheric reanalysis products. Their findings suggest that ocean processes play a crucial role in determining the seasonality of sea ice trends. They also reveal that the sea-ice response is regional.”

Underwater Glider Data Improved Intensity Forecasts of Hurricane Gonzalo

In a recent study published in Weather and Forecasting,* AOML researchers and their colleagues used NOAA’s HWRFHYCOM operational hurricane forecast model to quantify the impact of assimilating underwater glider data and other ocean observations into the intensity forecasts of Hurricane Gonzalo (2014). Gonzalo formed in the tropical North Atlantic east of the Lesser Antilles on October […]

On July 18, NOAA AOML and partner scientists will depart on the Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC-3) research cruise in support of NOAA’s Ocean Acidification Monitoring Program. This isn’t the first time researchers will head to sea in this region. Previous cruises have taken place along the east and Gulf of Mexico (GOM) coasts of the US in both 2007 and 2012. Together, these cruises provide coastal ocean measurements of unprecedented quality that are used both to improve our understanding of where ocean acidification (OA) is happening and how ocean chemistry patterns are changing over time. This will be the most comprehensive OA cruise to date in this region, set to include sampling in the international waters of Mexico for the first time. Ocean acidification is a global issue with global impacts, and international collaboration like this is vital to understanding and adapting to our changing oceans.

This June, AOML hosted students from the Frost Science Upward Bound Math and Science program. This program provides high school students with access to mentors and technology, interaction with scientists, as well the IMPACT (Integrated Marine Program and College Training) Summer Program, in which they delve specifically into marine science.

Experimental Reef Lab

Coral researchers at AOML unveiled a new state of the art experimental laboratory this spring at the University of Miami’s Rosenstiel campus. The new “Experimental Reef Laboratory” will allow NOAA scientists and colleagues to study the molecular mechanisms of coral resiliency. Modeling studies indicate that thermal stress and ocean acidification will worsen in the coming decades. Scientists designed the Experimental Reef Laboratory to study the combined effect of these two threats, and determine if some corals are able to persist in a changing environment.

Coral Biopsy

Scientists found that microbes and their genetic material from land-based sources of pollution could be found in reef water and in tissues of corals. This could affect the genomics of the native microbial communities found in coral reefs, which can impact how corals thrive and survive. These new insights highlight an additional potential threat to corals from land-based sources of pollution in southeast Florida, where corals are already under existential threat from warming oceans and resulting coral bleaching, disease and mortality.

The Atlantic Meridional Overturning Circulation (AMOC) transports the upper warm water northward and the deep cold water southward in the Atlantic, and is a key component of the global energy balance. In many of the climate models that participate the Coupled Model Inter-comparison Project Phase 5 (CMIP5), the amplitudes of the AMOC agree very well with or are even larger than the observed value of about 18 Sv at 26.5N; but they still show cold upper ocean temperature biases in the North Atlantic.

One of the most challenging questions in global climate change studies today is how quickly, or if, heat that accumulates within the Earth system penetrates into the deep ocean. Scientists with the University of Miami (UM), AOML, and NASA’s Jet Propulsion Laboratory (JPL) recently tackled this question by using a combination of present-day satellite and in situ observing systems to study the distribution of heat in the oceans. 

Scalloped Hammerhead Sharks

Coral scientists recently traveled to the Galapagos Islands to document coral reef health following the 2016-17 El Niño Southern Oscillation event (ENSO), which bathed the region in abnormally warm waters. Historically, these events have triggered coral bleaching and large-scale mortality, as seen in response to ENSO events of 1982-83 and 1997-98. Interestingly, these same reefs exhibited minimal bleaching in response to this most recent event. Scientists are determining whether this response is due to differing levels of heat stress, or an increased tolerance to warm water in the remnant coral communities.

Glider SG609 is one of four gliders that are part of the Hurricane Field Program at NOAA’s Atlantic Oceanographic and Meteorological Laboratory. AOML launched its glider project in 2014 with the goal of enhancing the understanding of air-sea interaction processes during tropical cyclones. Scientists and technicians from AOML and the University of Puerto Rico at Mayagues run the deployments and recoveries out of Isla Magueyes Marine Laboratories in Puerto Rico, which neighbors the colorful coastal island community of La Paguera.

Temperature Sensor

Warm ocean water can be a killer for coral reefs, and AOML recently developed a new inexpensive sensor to drastically improve our ability to measure and monitor changing temperatures on reefs at an unprecedented scale.  The low cost sea temperature sensor, known as InSituSea, costs roughly $10 in parts to produce while providing high accuracy (0.05-0.1 C) in measurement. With a production cost that is 10% of an off-the-shelf temperature sensor, colleagues have expressed strong interest in deploying the InSituSea sea temperature sensor at coral reefs around the world.

(c) Schematic diagram of the influence of the IPO on South Atlantic SSH and SAMOC variabilities. Heating anomaly in the atmosphere associated with the positive IPO generates Rossby wave source region extending from the tropical western Pacific toward South America (pink hatching). This generates a stationary wave pattern extending from the source region poleward around the southern tip of South America (labeled H and L for anticyclone and cyclone, respectively). This circulation produces anomalous westerlies in the South Atlantic between 30°S and 40°S, enhancing the northward Ekman transport, which in turn enhances the subtropical gyre circulation and northward SAMOC (dark green arrow).

This study explores potential factors that may influence decadal variability of the South Atlantic meridional overturning circulation (SAMOC) by using observational data as well as surface-forced ocean model runs and a fully coupled climate model run. 

King Tide

Tidal flooding from events such as the so-called “King Tides” and “Super Tides” are flooding urban coastal communities with increasing frequency as sea levels rise. These tidal flood waters can acquire a wide range of contaminants and toxins as a result of soaking in the built environment of urbanized coastlines. A multi- institutional, interdisciplinary research team, including scientists from AOML, is examining the types of contamination picked up from the urbanized coastal landscape and transported into coastal waters through tidal flooding.

CHAMP coral monitoring station

Coral Health and Monitoring Program (CHAMP) researchers at AOML have worked cooperatively with the Caribbean Community Climate Change Centre (CCCCC), headquartered in Belize, over the past several years to install Coral Reef Early Warning System (CREWS) stations at key coral reef sites in countries throughout the Caribbean. CREWS stations monitor an array of atmospheric and oceanographic parameters to assess the health and integrity of coral reefs. The stations are part of the CCCCC’s efforts to strengthen the Caribbean region’s ability to respond to climate variability, extreme weather conditions, pollution, and habitat change.

Trajectories of synthetic drifters

In a paper published in the Journal of Operational Oceanography, a team of scientists with the Physical Oceanography Division at AOML, the University of Santiago de Compostela in Spain, the University of Miami, the University of Hawaii, and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia analyzed possible pathways to link the location of the found debris in the southwestern Indian Ocean with potential crash sites, probably in the eastern Indian Ocean.

Coral Skeleton covered in reef organisms

The study, published in the Proceedings of the Royal Society B, measured changes in the reef framework in several naturally high-carbon dioxide settings near Papua New Guinea. For the first time, scientists found increased activity of worms and other organisms that bore into the reef structure, resulting in a net loss of the framework that is the foundation of coral reef ecosystems.

NOAA’s Hurricane Hunters fly into hurricanes to help study important features and improve forecasts. The photos below highlight two different flights, on October 5 & 6, 2016, that were taken from flights into Hurricane Matthew as it moved through the Atlantic and up the East Coast of the United States. Hurricane Matthew eventually moved off the East Coast and would dissipate out in the Atlantic Ocean. 

Hurricane Matthew Radar

NOAA’s hurricane hunter aircraft carry a unique radar that measures wind in hurricanes where there is rain. Located in the tail of the aircraft and known as the Tail Doppler Radar, this instrument produces images that can provide detailed pictures scientists use to study storm structure and changes. Scientists can also piece together wind speed information gathered over the course of a flight to paint a complete picture of the wind speed in the regions of the storm where the aircraft flies.

Hurricane Hunters Leaving for Tampa

There aren’t many people who can say they have flown directly into a hurricane, but on October 5, 2016, I had a very unique opportunity to fly into Hurricane Matthew with NOAA’s Hurricane Hunters. Matthew was quickly moving across the Atlantic Ocean, and each new forecast moved it closer to the East Coast of Florida. With the high potential for hurricane watches and warnings, NOAA started preparations for routine flight operations.

With hurricane season in full swing, NOAA will host a Reddit Ask Me Anything (AMA) about the Science of Hurricane Hunting to Improve Forecasts on September 22, 2016 at 1:00 p.m. Hurricane scientist Frank Marks, Sc.D., Director of the Hurricane Research Division at AOML, and P-3 hurricane hunter pilot Commander Justin Kibbey of the NOAA Corps will answer questions. The first half of hurricane season has produced a significant number of storms in the Atlantic and Gulf of Mexico. This AMA is a great opportunity to answer questions about how and why we study these storms.

The 2016 Atlantic Oceanographic and Meteorological Laboratories’ (AOML) cadre of summer interns inspired us with a very promising group of motivated individuals. Fourteen students came from all over the country to complete a wide array of projects in different thematic areas of AOML’s workforce; Physical Oceanography, Ocean Chemistry and Ecosystems, Hurricane Research, Engineering, and Communications.AOML is home to some of the nation’s leading scientists, and internships offer a great opportunity for students to learn alongside these experts and develop skills that they will take with them in the future. The summer internships also expose students to careers at a federal research laboratory. NOAA offices are located all across the country, so students who enjoy their summer internship can consider NOAA or other federal science agencies for future employment when they enter the workforce.

The new research published online August 10 in Nature Climate Change provides a stark look into the future of ocean acidification – the absorption by the global oceans of increasing amounts of human-caused carbon dioxide emissions. Scientists predict that elevated carbon dioxide absorbed by the global oceans will drive similar ecosystem shifts, making it difficult for coral to build skeletons and easier for other plants and animals to erode them.

Corals live and thrive by maintaining a careful balance between their growth rate and the rate of erosion. Scientists already know the projected increases in carbon dioxide in our global oceans, known as ocean acidification, will slow the rate at which corals build the hard calcium carbonate skeletons that are the foundation of their habitat. A new study published online today in PLOS ONE demonstrates that in naturally highly acidified waters, these coral skeletons will also face increased erosion from microscopic organisms, called bioerosion. The result is accelerated breakdown and loss of reef structures, and potentially the loss of essential habitat.

Hurricane Katrina from Space

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) are at the vanguard of hurricane research. Each hurricane season we fly into storms, pore over observations and models, and consider new technological developments to enhance NOAA’s observing capacity and improve track and intensity forecasts. The 2016 hurricane season will provide an opportunity for our scientists to test some of the most advanced and innovative technologies and refined forecasting tools to help better predict a storm’s future activity.

As a hurricane approaches landfall, citizens are hoping that they are adequately prepared for the potential damage from strong winds and rising oceans. NOAA’s job is to forecast the storm location and strength, or intensity, to help communities make the best informed decisions. For many scientists, predicting intensity is a challenge at the forefront of hurricane research, and in recent years advancements in observations and modeling have improved NOAA’s forecasts of intensity by 20%. We are now at the point where scientists can observe and predict with very fine detail what is happening in the inner core of the storm.

A team of NOAA oceanographers sets sail from Miami aboard the NOAA Ship Nancy Foster on May 7th to investigate ocean currents and fish larvae distribution in the southern Gulf of Mexico and western Caribbean. The joint cruise between NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and Southeast Fisheries Science Center (SEFSC) is a new chapter in a long-term effort that pools cross-line office resources to better understand the early life history and larval recruitment pathways of important fisheries in the region, including the ecologically important and commercially valuable Atlantic bluefin tuna.

Tornadoes are one of nature’s most destructive forces. Recent violent and widespread tornado outbreaks in the United States, such as occurred in the spring of 2011, have caused significant loss of life and property. Currently, our capacity to predict tornadoes and other severe weather risks does not extend beyond seven days. Extending severe weather outlooks beyond seven days will assist emergency managers, businesses, and the public prepare the resources needed to prevent economic losses and protect communities. So how can scientists better predict when and where tornadoes are likely to strike, before the tornado season begins?

In a recent paper published in the Journal of Climate, scientists with NOAA and the University of Miami have identified how variability in ocean circulation in the South Atlantic Ocean may influence global rainfall and climate patterns. The study by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) suggests that the South Atlantic is a potential predictor of global rainfall variability with a lead-time of approximately 20 years. This link between the South Atlantic Ocean and weather and climate could provide significant long-term insight for water management on a global scale.

A recent paper published in the Journal of Climate led by PHOD researchers Hosmay Lopez, Shenfu Dong, Sang-Ki Lee, and Gustavo Goni provides a physical mechanism on how low frequency variability of the South Atlantic Meridional Heat Transport (SAMHT) associated with the Atlantic Meridional Overturning Circulation ( AMOC) may influence decadal variability of atmospheric circulation and monsoons. This is the first attempt to link the South Atlantic Overturning Circulation variability to weather and climate.

The red and green shading denote the periods of the dominance of the geostrophic and Ekman components on the MOC, respectively. Image Credit: NOAA.

The Meridional Overturning Circulation (MOC) plays a critical role in global and regional heat and freshwater budgets. Recent studies have suggested the possibility of a southern origin of the anomalous MOC and meridional heat transport (MHT) in the Atlantic, through changes in the transport of warm/salty waters from the Indian Ocean into the South Atlantic basin. This possibility clearly manifests the importance of understanding the South Atlantic MOC (SAMOC). Observations in the South Atlantic have been historically sparse both in space and time compared to the North Atlantic. To enhance our understanding of the MOC and MHT variability in the South Atlantic, a new methodology is recently published to estimate the MOC/MHT by combining sea surface height measurements from satellite altimetry and in situ measurements (Dong et al., 2015).

Researchers with the Global Carbon Budget released their annual update for the global carbon budget in December 2015, revealing carbon dioxide (CO2) emissions from fossil fuels increased slightly in 2014 (+0.6%), but are projected to decline slightly (by est. -0.6%) in 2015. The global oceans serve as a natural buffer, offsetting increased emissions by absorbing an estimated 27% of human-produced CO2 from the atmosphere in 2014. Data collected, in part, from long-term surface ocean CO2 monitoring efforts, funded by NOAA’s Climate Program Office and the Ocean Acidification Program, indicate that the oceans removed about 10.7 billion tons of CO2 from the atmosphere in 2015.

Hurricanes are known to drive the cooling of surface waters as they travel over the ocean, leaving a cooling swath where they pass. The sea surface cooling is mostly caused by mixing forced by the strong winds of the hurricane, which occurs as the mixture of warm surface waters with colder waters that can be as deep as 100 m below the surface.

Collecting Data at Cheeca Rocks

AOML coral researchers conducted a number of reef monitoring activities during the month of October at Cheeca Rocks off of Islamorada, Florida. Among the activities was the installation of new sensors to measure pH and photosynthetic light levels at the on-site MapCO2 buoy. The team also conducted benthic surveys and deployed a pH sensor at an inshore patch reef where they are conducting an experiment to examine the impacts of bleaching across Florida Keys reefs. They were also joined by a colleague from the University of Miami who conducted photo mosaic surveys of the reefs. A photo mosaic is a tool used by researchers to map reefscapes and involves the stitching together of hundreds of photos taken simultaneously across the reef to form one giant image. Photo mosaics provide coral researchers with an important tool to more accurately document community-wide changes in reef health.

On October 15, 2015, the scientists, technicians, and engineers involved in the AOML Western Boundary Time Series (WBTS) project marked a milestone with the completion of the 100th successful dropsonde cruise in the Florida Current since the project’s inception in 2000.

In October, AOML scientists, technicians and engineers involved in the Western Boundary Time Series (WBTS) project completed the 100th successful dropsonde cruise in the Florida Current since the project’s inception in 2000. The dropsonde cruises measure volume transport in the Florida Current using an out-of-service telephone cable between Florida and Grand Bahama Island.

Map showing locations for the Coral Health and Monitoring Program.

AOML’s Coral Health and Monitoring Program (CHAMP) rolled out a new data source in October as part of its online data query tool. Optimally Interpolated Sea Surface Temperatures, or OISSTs, are data from microwave satellite observation platforms, products that are sourced from Remote Sensing Systems. Whereas other sea surface temperature sources might be missing data due to orbital gaps or non-ideal environmental conditions such as cloud cover or rainfall, the OISST platform corrects for these errors to provide a complete, daily sea surface temperature map that can benefit coral health and monitoring efforts worldwide.

NOAA selected AOML oceanographer Dr. Rik Wanninkhof in October 2015 to become a Senior Technical Scientist, the highest attainable level for federal research scientists within NOAA. Rik is an internationally recognized authority on air-sea gas transfer with close to 25 years of experience studying the effects of atmospheric carbon dioxide on the ocean. Senior Technical Scientist positions are held by individuals who achieve national and/or international distinction in their field through their high-level research.

On September 29th, researchers from AOML’s Environmental Microbiology Lab along with scientists from Florida International University’s Southeast Environmental Research Center collected water samples along Miami Beach during a king tide event, the highest astronomical tide of the year. Sample sites were located adjacent to pumps installed by the City of Miami Beach to actively pump super-tidal floodwaters out of the streets and back into Biscayne Bay. AOML’s team continuously monitored and collected water samples over a 5-hour period at locations in Maurice Gibb Memorial Park, along 14th Street, and at 27th Street and Indian Creek Drive. During sampling, physical water properties such as temperature, salinity, pH, turbidity, and dissolved oxygen content were also measured.

A team of NOAA scientists from the Southeast Fisheries Science Center (SEFSC) and AOML conducted a survey aboard the NOAA research vessel Hildebrand to capture, tag and release leatherback sea turtles in the Gulf of Mexico. The survey, which took place off the coast of the Florida Panhandle, was the first directed research on leatherbacks in Gulf waters. The team of scientists sought to obtain accurate information on these endangered animals in order to answer questions relating to habitat use, migrations, and distribution within the Gulf region. After locating a turtle with help from spotters in NOAA aircraft, each turtle was secured with a net and brought to the vessel to be measured and equipped with a satellite tag, which will collect data on dive patterns and water temperatures in addition to long-term movement. The team successfully tagged a total of six turtles during the survey. The team also assisted in the scheduled release of a female leatherback that had stranded earlier in September off of Fort Walton Beach, FL. The turtle, which had been rehabilitated at the local Gulfarium Marine Adventure Park, was brought aboard the R/V Hildebrand in Destin, FL and successfully released 20 miles offshore.

AOML scientists aboard the R/V F.G. Walton Smith conducted the bimonthly water quality research cruise in support of the South Florida Project during the week of September 21st. The AOML South Florida Project (SFP), and its associated field operations, have enabled scientists and resource managers to keep a watchful eye on the sensitive marine habitats found in the region and have served as a sentinel during periods when the ecosystem has been subjected to extreme events such as hurricanes, harmful algal blooms (HAB), and more recently, potential oil spill contaminants. Additionally, the AOML SFP has produced a comprehensive, long-term baseline regarding regional circulation, salinity, water quality, and biology for the ecosystem.

AOML’s ecosystem assessment and modeling group is collaborating with the protected species and biodiversity lab at NOAA’s SEFSC to begin a water quality monitoring survey of South Florida’s Biscayne Bay watershed. Biscayne Bay is a designated Habitat Focus Area under NOAA’s Habitat Blueprint, a program which offers opportunities for NOAA to partner with organizations to address coastal and marine habitat loss and degradation issues. Scientists will collect continuous temperature, salinity, turbidity, dissolved organic matter, and fluorescence measurements, as well as discrete samples for Chlorophyll a, nutrients, and phytoplankton. The surveys will occur quarterly and will examine the sources of potential contaminants from canals and waterways, and the subsequent effects these contaminants will have on the Bay.

AOML coral scientists participated in a NOAA National Marine Fisheries Service-led project to document coral spawning in the Florida Keys National Marine Sanctuary during August & September 2015. The project aims to measure spawning success for two imperiled Caribbean species, elkhorn coral (Acropora palmata) and mountainous star coral (Orbicella faveolata) in the Florida Keys. The team collected gametes from both species to be used in experiments that aim to improve the understanding of factors that may enhance the likelihood of coral larvae to survive and settle on the ocean floor. Experiments will also assess impacts of current and future global environmental changes, such as ocean acidification, on these vulnerable early life stages of corals.

For the third time in recorded history, a massive coral bleaching event is unfolding throughout the world’s oceans, stretching from the Indian Ocean to the Caribbean. Above average sea surface temperatures exacerbated by a strong El Niño could result in the planet losing up to 4,500 square miles of coral this year alone, according to NOAA. The global event is predicted to continue to impact reefs into the spring of 2016.

Photos taken from NOAA’s P-3 aircraft during Hurricane Hunter flights conducted on Saturday, August 22nd and Sunday, August 23rd inside Hurricane Danny. Peaking at Category 3 strength on Friday, August 21, Danny had maximum sustained winds of 115 mph as it churned in the Atlantic. Danny then weakened to a tropical depression due to interaction with high levels of wind shear and a mass of dry air in the Caribbean as it moved across the Lesser Antilles. The Hurricane Hunter missions profiled Danny’s wind structure with Tail Doppler Radar, conducted various projects in support of the Hurricane Research Division’s 2015 Field Program, and surveyed the ocean ahead of the storm in order to improve forecasts.

With the 2015 Atlantic hurricane season underway, researchers are pointing to the strong presence of El Niño as the major driver suppressing the development of tropical cyclones in the Atlantic basin. But what specific conditions are associated with El Niño that lead to a less than ideal environment for tropical cyclone development? Through research and observation, hurricane researchers know strong environmental wind shear is a major factor affecting potential hurricane development and growth. This hurricane season, AOML researchers are delving further into the relationship between wind shear and tropical cyclones.

The pathways of recently ventilated North Atlantic Deep Water (NADW) are part of the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). In the South Atlantic these pathways have been the subject of discussion for years, mostly due to the lack of observations. Knowledge of the pathways of the AMOC in the South Atlantic is a first order prerequisite for understanding the fluxes of climatically important properties.

The earth is warming, but temperatures in the atmosphere and at the sea surface that steadily rose in the last half-century have leveled off and slowed in the past decade, causing the appearance of an imbalance in Earth’s heat budget. Scientists are looking into the deep ocean to determine where this additional heat energy could be stored, and recently traced a pathway that leads to the Indian Ocean.

During the months of March & April, AOML researchers participated in the Khaled bin Sultan Living Oceans Foundation’s Global Reef Expedition cruise which took place in the waters of the British Indian Ocean Territory. Some of the areas explored included the Maldives and the Chagos archipelago, home to the world’s largest Marine Protected Area. Aboard the R/V Golden Shadow and working under the theme “Science Without Borders,” the Global Reef Expedition team researches remote coral reef locations around the globe documenting their health to better understand which factors are crucial to reef resilience. AOML has participated in 12 Global Reef Expedition cruises since June 2012.

Projected timing in years of the onset of annual severe bleaching for the Florida Reef Tract and the Bahamas at ~11 km resolution. Note that regions in red and orange, such as the Dry Tortugas, are projected to bleach annually starting in the early 2030s, while the more northern stretch of the Florida Keys near Biscayne Bay, are projected to bleach annually in the mid-2040s.

In a new study published April 1 in Global Change Biology, NOAA oceanographers and colleagues have developed a new method to produce high-resolution projections of the range and onset of severe annual coral bleaching for reefs in the Gulf of Mexico and Caribbean

AOML’s hurricane researchers conducted a number of field activities in August that provided data and critical insights into two Atlantic tropical cyclones, Danny and Erika. The two storms enabled researchers to test new instruments in support of the 2015 Hurricane Field Program and conduct research that will benefit future forecasts. Among the highlights were more than 15 successful manned and unmanned aircraft missions into Danny and Erika to collect and provide real-time data to the National Hurricane Center (NHC), as well as evaluate forecast models.

If you’ve ever sailed aboard a ship in the coastal ocean, or checked a weather report before going to the beach, then you are one of many millions of people who benefit from ocean observations. NOAA collects ocean observations and weather data to provide mariners with accurate forecasts of seas, as well as coastal forecasts and even regional climate predictions. It takes a lot of effort to maintain observations in all of the ocean basins to support these forecasts, and NOAA certainly can’t do it alone. Partnerships are essential to maintaining a network of free-floating buoys, known as drifters, and NOAA’s latest partner is not your typical research or ocean transportation vessel: the six sailboats and crew currently racing around the world in the Volvo Ocean Race.

Left: New Iridium antenna and housing. Right: Antenna installed aboard the CMA CGM Racine cargo vessel in Miami, FL, before the start of the January 2016 AX07 (Miami to Gibraltar) XBT transect.

Scientists and engineers from NOAA have successfully designed, built, and tested a new antenna system that dramatically increases data transmission reliability while drastically reducing operating costs. The new Iridium-based transmission system, developed by NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) & the Cooperative Institute for Marine & Atmospheric Studies (CIMAS), has no restrictions on data format or size, allowing data from various ocean and land-based observation platforms to be transmitted more reliably and at a fraction of the cost of the older Inmarsat-C platform. Since completion, the Iridium system has been adopted on a number of Expendable Bathythermographs (XBTs) observation transects and have been simultaneously tested and implemented in other AOML observing systems.

AOML physical oceanographers Molly Baringer, Ulises Rivero, Pedro Pena, Andrew Stefanick, Grant Rawson, Jay Hooper and Francis Bringas conducted a Western Boundary Times Series cruise aboard the UNOLS R/V Endeavor on February 15, 2015. Molly Baringer, AOML Deputy Director, served as chief scientist and was supported by additional crew from the University of Puerto Rico. Scientists measured full water column values of salinity, temperature, and oxygen. Scientists also telemetered data from a series of moorings along the 26th north parallel for a joint NOAA and National Science Foundation program designed to monitor the Atlantic meridional overturning circulation current. Francis Bringas also conducted a fall rate experiment that consisted of deploying 200 XBTs from different launch heights.

If you want to understand Earth’s climate and how it changes from year-to-year and decade-to-decade, look to the oceans, and follow the heat. The major driver in the redistribution of heat around the globe in the ocean-climate system is Meridional Overturning Circulation, or MOC. The MOC is a vertical circulation pattern that exchanges surface and deep waters via poleward movement of surface waters. As an example, the well known Gulf Stream on the eastern seaboard of North America carries warm water northward to the Greenland and Norwegian Seas, where it cools and sinks.

The Atlantic hurricane season will officially end November 30, and will be remembered as a relatively quiet season as was predicted. Still, the season afforded NOAA scientists with opportunities to produce new forecast products, showcase successful modeling advancements, and conduct research to benefit future forecasts.

During the month of October, the Central Caribbean Marine Institute (CCMI) finished redeploying their buoy, which is part of the Coral Reef Early Warning System (CREWS). The buoy was first deployed in October 2013 and needs to be returned to land each year for cleaning, repainting and instrumentation swap. The buoy was towed from its deployment site on October 14th and returned to position on October 29th. AOML’s Mike Jankulak worked remotely with CCMI personnel to update the buoy’s programming and develop procedures for instrument configuration. As of October 31st all data feeds from the buoy to AOML and NDBC has fully resumed.

Evolution of the mean difference between the time the observation is taken to the time the profile is available at the Global Argo Data Assembly Centers. The reduction of the elapsed time at the beginning of 2012 are due to improvements of the processing system, while the reduction of the elapsed time at end of 2012 is due to switching operational data processing from once daily on an old computer to twice daily on a new and faster computer. Software and schedule changes in 2014 lead to further reductions of the elapsed time. Image Credit: NOAA AOML.

The US Argo Data Assembly Center at PhOD used the transition to the NETCDF profile format version 3.0 to consolidate three processes into one process. This major development had multiple benefits. The primary benefit is that during the development stage the rapid changes in the float technology, for example the addition of sensors, were taken into account to increase the adaptability of the software to future changes of floats as well as the NETCDF profile format. Prior to this development, three programs required adaptation when float types with a new combination of sensors was deployed.

King Tide: tide at 10:30am shows high watermark on a bridge in Coconut Grove

The colloquial term ‘king tides’, referring to the highest astronomical tides of the year, is now part of most Miami Beach residents and city managers’ vocabulary. Exacerbated by rising seas, these seasonal tides can add up to 12 inches of water to the average high tide, threatening the urbanized landscape of Miami Beach. During these events, AOML’s Microbiology Team is on the scene to investigate these tidal waters as they rise and recede. The microbiologists are part of a research consortium for sea level rise and climate change, led by Florida International University’s Southeast Environmental Research Center. The research effort focuses on collecting samples and monitoring water quality at locations along the Biscayne Bay watershed where the City of Miami Beach has installed pumps to actively push these super-tidal floodwaters back into the bay.

On Tuesday, September 16, 2014, a new X/L-band satellite receiving system was installed on the roof of AOML, augmenting the existing L-band antenna. This new system will expand AOML capabilities to receive telemetry and create products from the next generation of NOAA’s polar-orbiting environmental satellites, including Suomi NPP and the Joint Polar Satellite System (JPSS) constellation. Infrared and microwave sounder data from the system will be delivered to NOAA NCEP for assimilation in NWP models.

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory are at the forefront of hurricane research to improve track and intensity forecasts. Every hurricane season they fly into storms, pour over observations and models, and consider new technological developments for how to enhance NOAA’s observing capabilities. The 2014 hurricane season will provide an opportunity to test some of the most advanced and innovative technologies, including unmanned hurricane hunter aircraft and sea gliders, which will help scientists better observe and, eventually, better predict a storm’s future activity.

2014 was a relatively warm summer in South Florida, and local divers noticed the effects of this sustained weather pattern. Below the ocean surface, corals were bleaching. In the month of August, the Coral Bleaching Early Warning Network, jointly supported by Mote Marine Lab and NOAA’s Florida Keys National Marine Sanctuary, received 34 reports describing paling or partial bleaching and an additional 19 reports indicating significant bleaching. Scientists continue to monitor the impact of this severe bleaching event to determine the extent of coral mortality.

NOAA hurricane hunters are prepared to enter a new chapter in the use of unmanned aircraft systems: deploying an unmanned aircraft from an airplane inside a hurricane. Starting on September 14, 2014, NOAA’s hurricane hunting manned aircraft fleet will fly into position to observe any developing tropical systems in the Atlantic using this new tool. The Coyote unmanned aircraft will be the first unmanned aircraft deployed directly inside a hurricane from NOAA hurricane hunter aircraft. The goal of the Coyote is to collect temperature, pressure and wind observations below 3,000 feet, where manned aircraft can not fly safely.

NOAA successfully deployed unmanned aircraft from a NOAA P-3 Hurricane Hunter directly into a hurricane for the first time. NOAA deployed four Coyote Unmanned Aircraft Systems (UAS) in Hurricane Edouard during flights conducted September 15-17, 2014 out of Bermuda. Scientists on board the P-3 aircraft received meteorological data from the Coyote UAS in both the eye and surrounding eyewall of Hurricane Edouard.

Kids Deploying Global Drifters

Drifting buoys are a primary tool used by the oceanographic community to measure ocean surface circulation at unprecedented resolution. A drifter is composed of a surface float, which includes a transmitter to relay data via satellite, and a thermometer that reads temperature a few centimeters below the air-sea interface. The surface float is tethered to a holey sock drogue (a.k.a. “sea anchor”), centered at 15 m depth. The drifter follows the ocean surface current flow integrated over the drogue depth.

Underwater glider SG610, deployed on July 14, is located in the Caribbean Sea. This glider navigated in a SW, then in a SE, and now in a SW direction since it was deployed. The temperature and salinity profile observations indicate that on July 25 this glider started sampling waters of a cyclonic eddy that is now centered at approximately 16.5°N, 67.5°W, and has a radius of ~0.75deg as derived from satellite altimetry observations. These profile observations show a decrease in the salinity maximum, and a shallowing of the depth of this maximum salinity and of the depth of the 26°C isotherm.

NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) participated in Ocean Sampling Day on June 21, the first global simultaneous sampling for microbes in ocean, coastal and Great Lakes waters. Over time, sampling will support international and NOAA missions to provide a snapshot of the diversity of microbes, their functions, and their potential economic benefits. Among other economic applications, microbes have been used for novel medicines, as biofuels, and to consume spilled oil. Organized and led by the European Union’s MicroB3 organization, NOAA coordinated twelve sampling sites for Ocean Sampling Day 2014 within U.S. coastal waters.

The Marine and Estuarine Goal Setting for South Florida (MARES) project, led by NOAA’s Cooperative Institute for Marine and Atmospheric Studies at the University of Miami, continues to increase awareness of and appreciation for the value of coastal marine ecosystems, and their impacts upon human society. From 2009 through 2013, NOAA’s National Centers for Coastal Ocean Science funded MARES with the goal of creating a consensus-based process for managing South Florida’s coastal marine environments. MARES is unique in that it was among the first major efforts to include human benefits in a systematic framework to enable integrated ecosystem based management. The MARES approach embodies NOAA’s effort to serve as the Nation’s environmental intelligence agency by providing actionable information from science-based models to support environmentally-sensitive decisions made every day by individuals, communities, and governments.

Results from research performed by Dillon Amaya, an undergraduate Hollings Scholar from Texas A&M University, were published recently in Journal of Geophysical Research. Dillon’s work was carried out in the Physical Oceanography Division of AOML during the summer of 2013 and focused on understanding the impacts of different types of El Niño events (“canonical” and “Modoki”) on sea surface temperatures in the tropical Atlantic. The main result from the research is that Modoki El Niño;s fail to produce significant warming in the tropical North Atlantic, in contrast to the well known warming following canonical events.

Schmid) described for the first time the mean vertical and cross-equatorial structure of the upper-ocean meridional currents in the Atlantic cold tongue region, using in situ observations including drifters, Argo, shipboard/lowered ADCP, and moored ADCP. This study involves collaborations with scientists from the University of Miami, Scripps Institution of Oceanography, and several international institutions and makes use of data from several major tropical Atlantic field programs including NOAA’s PIRATA Northeast Extension.

The AOML technology test of a system to autonomously retrieve data from subsurface moored instruments has had a major success. The Adaptable Bottom Instrument Information Shuttle System (ABIISS) is in the midst of its first 4000+ meter test, and on November 6th, 2015 the first data pod surfaced and successfully transmitted its daily data record from the ocean bottom pressure-equipped inverted echo […]

The 2013 Atlantic hurricane season, which officially ended on November 30th, will be noted in the record books as having been a relatively quiet year with the fewest hurricanes since 1982. In fact, it will be ranked as the sixth least-active Atlantic hurricane season since 1950. Despite this, the 2013 season was quite an active […]

Sketch of the physical processes linking the major summer monsoons in the NH and the southern subtropical anticyclones. The three regions of rising motion, the three regions of sinking motion and the regions of southern subtropical anticyclones affected are filled with gray, sky blue and red colors, respectively. The sinking regions in the southeastern tropical Pacific and the southeastern tropical Atlantic are indicated by sky blue borderlines. Thick black arrows represent divergent winds in the upper level, while light green arrows represent the paths of the stationary barotropic Rossby waves forced by diabatic cooling over the three regions of sinking motion and by diabatic heating in the Indian summer monsoon region.

In a recent article accepted for publication in the Journal of Climate, scientists in PhOD, S.-K. Lee (CIMAS) and C. Wang collaborated with R. Mechoso and D. Neelin, both at UCLA, to explore why the southern subtropical anticyclones are notably stronger in the austral winter than in summer, which is in contrast with the Northern Hemisphere (NH) in which subtropical anticyclones are more intense in summer according to the monsoon heating paradigm. They performed model experiments to show that during the boreal summer enhanced tropical convection activity in the NH plays important roles in strengthening the southern subtropical anticyclones.

While tropical cyclones can dramatically impact coral reefs, a recent study reveals their passage also exacerbates ocean acidification, rendering reef structures even more vulnerable to damage. Calcifying marine organisms such as corals that thrive in alkaline-rich waters are increasingly imperiled as seawater becomes more acidic due to the ocean’s uptake of carbon dioxide. The detrimental effects upon these organisms have been documented, but less is known about how reefs might react to ocean acidification when coupled with an additional stress factor such as a tropical cyclone.

NOAA hurricane scientists are expanding their observations this summer, working with NASA’s Hurricane and Severe Storm Sentinel (HS3) mission and its innovative Global Hawk unmanned aerial vehicles to push the boundaries of hurricane operations. NASA looked to NOAA’s hurricane experts to augment its HS3 science team, supporting their five-year mission to investigate the processes that underlie hurricane formation and intensity change in the Atlantic Ocean basin.

In a recent study by scientists at Boston University, PHOD, and NCAR, a new mechanism was uncovered for initiating ENSO events wherein SLP-generated North Pacific trade winds induce subsurface heat content changes that serve as precursors to El Ninos. This trade-wind charging mechanism of the equatorial Pacific is fundamentally different from any previously diagnosed, and studies examining the surface and subsurface ocean dynamics associated with this mechanism are underway.

Scientists at PHOD developed a synthetic method, which combines high-density expendable bathythermograph (XBT) temperature data along the AX08 XBT transect (which runs between Cape Town and NYC) with altimetric sea level anomalies, to estimate the variability of the off-equatorial currents, such as the North Equatorial Countercurrent and the North Equatorial Undercurrent, on seasonal to interannual timescales. Understanding how the ocean dynamics is liked to anomalies of temperature and wind-stress in the tropical Atlantic is critical to understand the climate and weather variability in the adjacent continental areas.

In its 2013 Atlantic hurricane season outlook issued today, NOAA’s Climate Prediction Center is forecasting an active or extremely active season this year.For the six-month hurricane season, which begins June 1, NOAA’s Atlantic Hurricane Season Outlook says there is a 70 percent likelihood of 13 to 20 named storms (winds of 39 mph or higher), of which 7 to 11 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).

Using over 30 years of observations from drogued, satellite-tracked surface drifting buoys, Lumpkin and Johnson (2013) developed a methodology to map seasonally-varying surface currents at 1/2 degree resolution. Results from this study can be used to better understand how the ocean transports properties like heat, salt, and passive tracers, and serves as a reference to study changes in ocean currents over time. One key result from this study is the global distribution of mean, seasonal and eddy kinetic energy, which totals 4.6x1017J in the upper 30 m of the ocean and reveals the presence of three large eddy

AOML partnered with NOAA’s Southeast Fisheries Science Center (SEFSC) to host an open house for local students and the public on May 24th and 25th. The two-day event drew 425 students and 275 members of the public for a total of 700 visitors. Staff from Representative Ileana Ros-Lehtinen’s office (FL-27) and Senator Marco Rubio’s (FL) office also participated in the very successful event.

Using over 30 years of observations from satellite-tracked surface drifting buoys, NOAA oceanographers derived a global climatology of seasonally-varying ocean surface currents at one-half degree resolution. This data set can be used to better understand how the ocean transports properties like heat, salt, and passive tracers, and as a reference to study changes in ocean […]

NOAA oceanographers traveled to Saipan this spring to refurbish the Coral Reef Early Warning System (CREWS) station in Lao Lao Bay and conduct site surveys for the potential location of a moored autonomous pCO2 (MApCO2) buoy. Staff from the Pacific Islands Ocean Observing System (PacIOOS) program in Honolulu joined them during the site visit hosted by the Division of Environmental Quality (DEQ) of the Commonwealth of the Northern Mariana Islands (CNMI).

The record-breaking U.S. tornado outbreaks in the spring of 2011 prompt the need to identify long-term climate signals that could potentially provide seasonal predictability for U.S. tornado outbreaks. A new research led by scientists in the Physical Oceanography Division of NOAA-AOML used both observations and model experiments to show that a positive phase Trans-Niño may be one such climate signal.

Upper Ocean Heat content during the intensification of Hurricanes Katrina (left) and Isaac (right) Image Credit: New York Times

A news article that appeared on August 27 shows the ocean conditions in the Gulf of Mexico during hurricanes Katrina (August 2005) and Isaac (August 2012). The ocean conditions are depicted by the upper ocean heat content derived from satellite altimetry using a methodology developed at NOAA/AOML. The upper ocean heat content had larger values during Katrina mainly due to an anticyclonic warm ring and an extended Loop Current. These conditions, not found during the passage of Hurricane Isaac, partly contributed to the intensification of Katrina.

A new study led by researchers from University of Miami, NOAA-AOML, IFM-GEOMAR, and NCAR explores why the Atlantic Ocean has warmed substantially more than any other ocean basin since the 1950s. The research article published in the Geophysical Research letters evidences that the observed large warming of the Atlantic Ocean since the 1950s is largely induced by an increase in the inter-ocean heat transport from the Indian Ocean via the Agulhas leakage. The study points to an important role played by the Atlantic meridional overturning circulation (AMOC) in the South Atlantic in enhancing the secular warming of the Atlantic Ocean.

IPCC projected changes of bluefin tuna’s spawning habitat in the Gulf of Mexico due to anthropogenic global warming for three time frames: top (late 20th century), (middle) mid 21st century and (bottom) late 21st century. The colors indicate preferred spawning habitat, with yellow/orange for favored locations and blue/purple for non-ideal regions. Liu and Lee’s research indicates that the area of spawning habitat for the bluefin tuna may not be as drastically reduced as in the IPCC results shown in these figures. Image Credit: NOAA AOML.

A joint workshop hosted by NOAA and the National Aeronautics and Space Administration (NASA) for bluefin tuna research was held at the University of Miami on December 6-7th. Researchers with AOML’s Physical Oceanography Division (PhOD) presented the results of their collaborative efforts with NOAA’s Southeast Fisheries Science Center (SEFSC), which have focused on the link between the ocean and stock assessment species of relevant commercial importance.
