Ocean Month: Exploring and understanding our ocean through research cruises

AOML Communications — Wed, 25 Jun 2025 18:38:18 +0000

Research cruises are essential for scientists to collect data, deploy instrumentation, and maintain ocean observing systems. NOAA regularly conducts research at sea to study the ocean and atmosphere, advancing our understanding of the ocean, monitoring ocean conditions, and ensuring sustainable fisheries and healthy marine habitats. These expeditions provide essential data for weather prediction, ocean acidification […]

Australia to Thailand: I09N GO-SHIP cruise completes voyage

AOML Communications — Wed, 28 May 2025 14:44:32 +0000

After nearly 40 days at sea, the I09N GO-SHIP cruise (short for “Global Ocean Ship-based Hydrographic Investigations Program”) aboard the R/V Thomas G. Thompson arrived in Phuket, Thailand on April 27th, successfully completing its mission surveying both the Indian Ocean and Bay of Bengal. After departing from Fremantle, Australia on March 21st, the international team of researchers spent weeks collecting data essential for investigating global changes in ocean physics, chemistry, and biology.

New study demonstrates the impacts of multiple stressors on reef-building corals

Chris Malanuk — Wed, 26 Mar 2025 19:53:01 +0000

In a new study, scientists at AOML and the University of Miami’s Cooperative Institute for Marine and Atmospheric Sciences (CIMAS) demonstrated how some genotypes of the reef-building coral Acropora cervicornis (Staghorn Coral), listed on the Endangered Species Act, proved resilient when exposed to high nutrient levels or disease, but not when the two stressors were […]

A Collaborative Effort Investigates the Biological Carbon Pump, Deploying Sediment Traps Hundreds of Meters Below

AOML Communications — Tue, 23 Jan 2024 14:22:01 +0000

A team of scientists from AOML, the U.S. Geological Survey (USGS), and the University of South Carolina retrieve a sediment trap from the Gulf of America, spending months processing and examining the flurry of microscopic shells and environmental DNA (eDNA) of biological debris collected by the trap, known as “marine snow.” This collaborative NOAA–USGS research project uses these sediment trap samples to investigate the biological carbon pump, the ocean’s role in removing atmospheric carbon, and climate change patterns.

Failing Upwards: Developing an Autonomous Surface Vehicle to Advance ‘Omics Research

AOML Communications — Thu, 16 Nov 2023 15:44:33 +0000

For engineers and scientists, sometimes failure means progress. When developing a new technology, the process is to field test, fail, tweak, and test again, each time failing a little less and learning what does and does not work until – finally – they get it right. On August 5, 2023, scientists from NOAA’s Great Lakes […]

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

AOML Communications — Thu, 17 Aug 2023 17:25:45 +0000

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

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

AOML Communications — Tue, 06 Jun 2023 15:44:42 +0000

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 America 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.
