The ocean plays a key role in mitigating climate change by absorbing about 25 percent of the carbon dioxide gas (CO2) released into the atmosphere each year by human activities. However, this comes at a cost to ocean health because the uptake of this...
July – August 2022: PMEL's Sharon Walker joined a team of engineers, multibeam mapping experts, and scientists from around the globe to complete a high-resolution bathymetric and hydrothermal plume survey of the post-eruption caldera at the Hunga...
July 29 - August 4: A team of NOAA and University of Washington Cooperative Institute scientists flew over Alaskan waters to conduct renewed research on Arctic ocean heat flows. Scientists deployed 30 floats from NOAA aircraft that will provide key...
NOAA PMEL, University of Washington and OptoKnowledge Systems, Inc. (OKSI) successfully conducted the first deep water test of a new methane analyzer to measure the concentration and carbon isotope ratio of methane near Axial Seamount. This new...
An annual survey is underway to provide baseline fisheries and oceanographic data to support sustainable management of living resources in the Bering Sea and the rapidly changing US Arctic ecosystem. These surveys provide key data in understanding...
March 31, 2022: The Kuroshio Extension Observatory (KEO) moored buoy was successfully deployed by NOAA PMEL and partners, renewing an ongoing OceanSITES time series that began almost 18 years ago. First deployed in 2004, its time series was disrupted...
A new video highlighting PMEL's acoustics research and eDNA innovations to study Blue Whales off the coast of Newport, Oregon has been released in the “PMEL at Work” YouTube series.
This video features PMEL’s Acoustic Program’s Bob Dziak and...
Microscopic organisms in the surface ocean, called phytoplankton, use photosynthesis to convert carbon dioxide into organic compounds like carbohydrates, fats, and proteins. Only a small fraction of this organic matter produced by phytoplankton is...
February 1 - March 7: NOAA PMEL scientists join NOAA Fisheries and an international team of researchers aboard the NOAA R/V Shimada to provide expertise in physical oceanography and lead hydrographic data collection, nutrient sampling, analysis and...
On January 15, 2022, the Hunga Tonga-Hunga Ha’apai volcano erupted off the coast of Tonga in the South Pacific Ocean, generating a tsunami and triggering tsunami alerts around the world. Most tsunamis are commonly caused by earthquakes and only about...
A research team led by NOAA’s Cooperative Institute for Marine Ecosystem and Resource Studies at Oregon State University has developed an automated method that can accurately identify calls from a family of fishes.
The method takes advantage of data...
NOAA's 2021 Arctic Report Card, released today at the American Geophysical Union’s Fall Meeting, documents the numerous ways that climate change continues to fundamentally alter this once reliably-frozen region, as increasing heat and the loss of ice...
Saildrone 1045, one of the five drones PMEL and AOML deployed in the western Atlantic was steered into position to intercept Category 4 Hurricane Sam on September 30, 2021 to record critical data. The encounter required precise interpretation of...
The 31st annual State of the Climate report confirmed that several markers such as sea level, ocean heat content, and permafrost in 2020 once again broke records set just one year prior. 2020 was also among the three warmest years in records dating...
