Floating ice, freezing temperatures: Four facts about the I08S GO-SHIP cruise to Antarctica
Floating ice, freezing temperatures, and streaks of lights in the night sky. The I08S GO-SHIP cruise successfully concluded on April 1st.
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.
Global Atmospheric Carbon Dioxide Levels Continue to Rise
Global carbon dioxide emissions in 2022 remain at record levels and natural carbon sinks are being impacted by climate change, according to a report published last week by the Global Carbon Project.
State of the Climate in 2021 Report Released
The State of the Climate in 2021 report was released today by the American Meteorological Society, showing greenhouse gas concentrations, global sea levels, and ocean heat content reached record highs in 2021 despite a La Niña event taking place in the Pacific Ocean.
Study Explores the Relationship of Anthropogenic Carbon and Ocean Circulation
In a recently published study in Nature Geoscience, scientists at AOML and international partners quantified the strength and variability of anthropogenic (man-made) carbon (Canth) transport in the North Atlantic Ocean. The study found that buildup of Canth in the North Atlantic is sensitive to the Atlantic Meridional Overturning Circulation (AMOC) strength and to Canth uptake at the ocean’s surface.
UN Ocean Decade Endorses Several AOML Collaborative Initiatives
In 2017, the United Nations General Assembly proclaimed the time frame of 2021-2030 as the UN Decade of Ocean Science for Sustainable Development, also known as the “Ocean Decade,” to address the degradation of the ocean and encourage innovative science initiatives to better understand and ultimately reverse its declining health.
