Scientists at AOML measure ocean’s crucial buffering against rising global carbon emissions 

Every year, scientists at AOML participate in the international effort led by the University of Exeter’s Global Systems Institute in developing the annual Global Carbon Budget Report, an assessment of global carbon emissions and the progress towards achieving the climate goals set by the 2016 Paris Agreement. The 2024 Global Carbon Budget Report now indicates […]

Ships of Opportunity: Crossing the Arctic to investigate the ocean’s uptake of carbon and increasing Ocean Acidification

The air and surface temperature tip just above freezing.  Cruiseliner Ponant’s 492-ft vessel Le Commandant Charcot floats idle at marked coordinates in the Arctic tundra between Alaska and Norway. On the aft deck, a team of scientists deploys Niskin bottles using a handcrank to the depths, collecting water samples 900 meters below an ocean blanketed […]

2023 Global Carbon Budget Report Emphasizes Urgent Need to Reduce Global Emissions

According to the newest Global Carbon Budget report, global emissions continue to rise and must be significantly reduced to meet global climate targets and avoid severe and deleterious effects of climate change. In 2023, atmospheric carbon dioxide (CO2) concentrations are expected to reach 419.2 ppm, an estimated 51% above pre-industrial levels, with 36.8 billion metric [...]

Landmark study analyzes global ocean carbon storage over two decades, indicates weakening of ocean carbon sink

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 […]

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

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 Scientists Publish a New River Chemistry and Discharge Dataset for U.S. Rivers

A new river chemistry and discharge dataset for U.S. coasts has been released. A recent publication by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), Northern Gulf Institute (NGI), and NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) provides a river chemistry and discharge dataset for 140 U.S. rivers along the West, East, and Gulf of Mexico coasts, based on historical records from the U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers. This dataset will be very useful for regional ocean biogeochemical modeling and carbon chemistry studies.

New study establishes monitoring framework for evaluating reef persistence under climate change and ocean acidification

Coral scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and University of Miami Cooperative Institute of Marine and Atmospheric Science (CIMAS) developed a new modeling approach, for evaluating coral reef persistence under climate change scenarios. Aiming to improve coral restoration efforts, this new user-friendly framework has been created as a helpful tool for coral reef scientists and managers to address the increasing vulnerability of these vital ecosystems.
