The Atlantic Meridional Overturning Circulation is weakening in the deep sea of the North Atlantic Ocean, Study Finds

AOML Communications — Thu, 18 Apr 2024 14:58:59 +0000

Just in! A new study, which analyzed mooring observations and hydrographic data, found the Atlantic Meridional Overturning Circulation (AMOC) abyssal limb in the North Atlantic has weakened over the past two decades contributing to sea level rise in the region.

From Mississippi to Australia: 3 Research Cruises Depart to Improve Understanding of the Atlantic and Southern Ocean

AOML Communications — Tue, 13 Feb 2024 22:16:57 +0000

Scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) are gearing up for a busy season at sea with three research cruises departing in the month of February. The A13.5 Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) cruise, the I08S GO-SHIP cruise, and the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) Northeast Extension cruise will all depart in February to collect samples from the surface to the depths of the ocean and improve our understanding of ocean circulation, carbon uptake, biological conditions, and climate variability.

New Mapping Method Uses Sustained Observations to Estimate AMOC at 22.5°S

AOML Communications — Thu, 25 Jan 2024 16:58:33 +0000

Changes in the Atlantic Meridional Overturning Circulation (AMOC) and its transport of heat can affect climate and weather patterns, regional sea levels, and ecosystems. A new study led by Ivenis Pita, a University of Miami PhD student working at NOAA’s Atlantic Oceanographic and Meteorological Laboratory/ the Cooperative Institute of Marine and Atmospheric Studies (CIMAS), is the first to estimate the AMOC and heat transport at 22.5°S in the South Atlantic, demonstrating the importance of sustained in situ observations to monitor the state of the AMOC.

AOML Begins Tenth Year of Hurricane Glider Operations

AOML Communications — Fri, 14 Jul 2023 19:49:00 +0000

This summer marks AOML’s tenth consecutive year of gathering underwater glider observations during the Atlantic hurricane season. The project began in 2014 with two gliders deployed off Puerto Rico to study the ocean’s role in tropical cyclone development and intensification. Since then, glider observations have become an integral part of the data gathered annually to improve tropical cyclone forecasts, as well as better understand how the ocean and atmosphere interact during the passage of tropical cyclones.

Fifty-Five Days at Sea: Collecting Oceanographic Data from Brazil to Iceland

AOML Communications — Thu, 08 Jun 2023 17:27:17 +0000

On May 9, a team of scientists aboard the NOAA Ship Ronald H. Brown arrived at their final destination in Reykjavik, Iceland following 55 days at sea. The team of 50 scientists and 28 crew members followed a track through the North Atlantic, from Brazil to Iceland, referred to as the A16N transect, and successfully completed 150 stations, collecting over 3,000 samples from the Atlantic’s surface to the seafloor, giving scientists a holistic snapshot of the Atlantic Ocean basin.

NOAA Cruise Ensures Flow of Critical Climate and Weather Data and Supports Collaborative Science

AOML Communications — Tue, 07 Feb 2023 21:39:01 +0000

Researchers with NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), NOAA’s Pacific Marine Environmental Laboratory (PMEL), NOAA’s National Environmental Satellite, Data and Information Service, and partners set sail from Bridgetown, Barbados aboard NOAA Ship Ronald H. Brown on November 1st, 2022. Over the next 40 days, the crew and scientists recovered and redeployed key moorings in the Prediction and Research Moored Array in the Tropical Atlantic (PIRATA), deployed an additional mooring, and serviced two equatorial PIRATA buoys in support of the PIRATA Northeast Extension project and broader PIRATA objectives. They also conducted a number of research projects on the ocean and atmosphere that advance our understanding of carbon absorption in the ocean and atmospheric pollution.
