Collecting Data at Cheeca Rocks

Coral Team Conducts Monitoring Activities 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.

100th Successful Dropsonde Cruise for the Western Boundary Time Series Project

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.

AOML Researchers Take Water Samples at Annual King Tide

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.

SEFSC & AOML Partner to Tag Leatherback Turtles in the Gulf of Mexico

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 Conducts Water Quality Monitoring in Florida Bay

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 Begins Biscayne Bay Canal Sampling Surveys

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.

Video: Coral Spawning in the Florida Keys

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.

Tropical Storm Fred

On September 5th, NASA’s Global Hawk took off from Wallops Island, Virginia to fly a 24 hour mission over Tropical Storm Fred. The Global Hawk launched dropsondes to measure the wind structure of the storm and gathered other meteorological data such as temperature and moisture with instruments on board. The Global Hawk is part of NOAA’s Sensing Hazards with Operational Unmanned Technology (SHOUT) field campaign.

Tropical Storm Erika

AOML is partnering with Woods Hole Oceanographic Institution in their effort to deploy eight more Air-Launched Autonomous Micro Observer (ALAMO) floats in the path of Tropical Storm Erika. ALAMO profiling floats will be air-deployed through a chute in the belly of a US Air Force C-130 airplane. ALAMOs are a smaller Argo-style floats that will make 11 profile per day of the upper ocean down to 300m.  They communicate via satellite and AOML will receive and conduct data processing to upload ocean temperature data onto the Global Telecommunication System so that it can be incorporated into ocean models. The ALAMO floats are manufactured by MRV Systems.

Hurricane Danny

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.
