The Atlantic Meridional Overturning Circulation is weakening in the deep sea of the North Atlantic Ocean, Study Finds /atlantic-meridional-overturning-circulation-weakening-in-the-deep-sea-of-north-atlantic/ Thu, 18 Apr 2024 14:58:59 +0000 /?p=76120 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 /3-research-cruises-depart-to-improve-understanding-of-atlantic-and-southern-ocean/ Tue, 13 Feb 2024 22:16:57 +0000 /?p=72633 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 /new-mapping-method-uses-sustained-observations-to-estimate-amoc-at-22-5s/ Thu, 25 Jan 2024 16:58:33 +0000 /?p=72090 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.

NOAA Measures Hurricane Tammy from Satellites through the Sea /noaa-altius-saildrone-mission-into-tammy/ Mon, 30 Oct 2023 19:38:01 +0000 /?p=68213 NOAA hurricane researchers successfully deployed a new uncrewed aircraft system (UAS) into Tropical Storm Tammy (2023) near an uncrewed surfance vehicle, saildrone, to measure parts of the storm too dangerous for humans to go. The Altius 600 UAS was launched from the NOAA WP-3D Orion Hurricane Hunter aircraft by scientists from NOAA’s Atlantic Oceanographic and Meteorological Laboratory during missions into the storm in coordination with the saildrone researchers and pilots.

Study Finds Atlantic Meridional Overturning Circulation Increases Flood Risk Along the United States Southeastern Coast /study-finds-amoc-increases-flood-risk-along-the-us-southeastern-coast/ Fri, 01 Sep 2023 16:56:47 +0000 /?p=66047 Sea level rise is one of the most challenging consequences of global warming. A new collaborative study led by Dr. Denis Volkov from NOAA-AOML and the University of Miami’s Cooperative Institute of Marine and Atmospheric Studies found that Atlantic Meridional Overturning Circulation (AMOC) induced changes in basin-wide ocean heat content are influencing the frequency of floods along the United States southeastern coast.

Landmark study analyzes global ocean carbon storage over two decades, indicates weakening of ocean carbon sink /ocean-carbon-sink-could-be-weakening/ Thu, 17 Aug 2023 17:25:45 +0000 /?p=65204 A landmark study published last week demonstrates that the ocean’s role as a carbon sink and its ability to store anthropogenic, or human-caused, carbon may be weakening. A collaboration among international researchers led by Jens Daniel Müller, Ph.D. (ETH Zurich), this study captures a snapshot of three decades of global interior ocean measurements to determine […]

AOML Begins Tenth Year of Hurricane Glider Operations /ten-years-of-hurricane-glider-operations/ Fri, 14 Jul 2023 19:49:00 +0000 /?p=62253 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.
