Improving Monitoring of Coastal Inundations of Sargassum with Wind and Citizen Science Data

AOML Communications — Mon, 14 Aug 2023 17:39:26 +0000

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.

NOAA Scientists Detect a Reshaping of the Meridional Overturning Circulation in the Southern Ocean

AOML Communications — Wed, 29 Mar 2023 12:56:10 +0000

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.

2020 State of the Climate Report Shows Global Ocean Processes are Shifting

AOML Communications — Wed, 25 Aug 2021 19:17:12 +0000

Today, August 25th, the 2020 State of the Climate report was released by the American Meteorological Society, showing 2020 to be one of the hottest years on record since the start of the Industrial Revolution. Even with environmental cooling factors, such as the transition from the El Niño of 2018-2019 to the La Niña of late 2020, global trends indicate the Earth is warming and sea level is rising. Throughout the report, environmental processes that influence climate and these warming trends are documented.

The Global Drifter Program Launches a New Interactive Map Tool

AOML Communications — Mon, 21 Dec 2020 15:30:03 +0000

The Global Drifter Program’s (GDP) Drifter Data Assembly Center (DAC) at AOML has launched a new interactive map of the global drifter array. This new tool features the ability to zoom and scroll, hover the cursor over drifters to get their identification numbers, and click to see data and metadata including deployment information, manufacturer, and drifter type in an ID card that can be viewed as a high-resolution image with an additional click.

First-ever Daily Time Series Reveals the Strength of the Deep Ocean Circulation in the South Atlantic

AOML Communications — Wed, 05 Aug 2020 17:56:40 +0000

In a recent study published in the journal Science Advances, oceanographers at AOML and the Cooperative Institute for Marine and Atmospheric Studies for the first time describe the daily variability of the circulation of key deep currents in the South Atlantic Ocean that are linked to climate and weather. The study found that the circulation patterns in the upper and deeper layers of the South Atlantic often vary independently of each other, an important new result about the broader Meridional Overturning Circulation (MOC) in the Atlantic.

AOML scientists partnered with the U.S. Air Force 53rd Reconnaissance Squadron “Hurricane Hunters” to deploy eight drifting buoys in advance of Tropical Storm Isaias on August 3, 2020 off the Carolina coast, in collaboration with the National Weather Service (NWS), National Hurricane Center (NHC), and Scripps Institution of Oceanography.

Global Meridional Overturning Circulation Revisited

AOML Communications — Thu, 07 Feb 2019 16:41:07 +0000

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.

NOAA’s Global Drifter Program: Ocean Dynamics Data Improves Forecasting and Coastal Safety

AOML Communications — Wed, 06 Jun 2018 19:14:41 +0000

NOAA’s Global Drifter Program is a globally collaborative research project that provides near real-time marine data for the world. It allows us to record data for weather forecasts, track decadal patterns, and pinpoint inter-annual climate variations like El Nino Southern Oscillation. Global drifters provide observational verification for weather models, calibrate satellite observations, and collect and transfer new data about the ocean temperature, currents and barometric pressure.
