The journal Nature Geoscience published a paper by Tom Delworth and his colleagues examining how a natural atmospheric force--the North Atlantic Oscillation--may be changing ocean currents in the North Atlantic. Among other impacts, the stronger ocean currents increase the amount of heat flowing toward polar areas, which could speed up Arctic ice melt and affect how hurricanes form. We asked Delworth a few questions about his study:
NOAA Research and NOAA Fisheries have teamed up with academic and private sector partners to test innovative technologies that, if successful, will enable researchers to gather information on ocean conditions and marine species in remote areas of the ocean that are costly to reach and difficult to study.
The record heat baking Alaska is poised to smash a host of climate records in 2016, including the earliest snowmelt date at NOAA’s Barrow Observatory, the northernmost point in the nation.
(September 1) Today NOAA released a free, downloadable flat screen version of its popular Science On a Sphere® (SOS), SOS ExplorerTM. This new way to display the dynamics of Earth’s weather and climate, plate tectonics and more will help teachers bring these stunning science visualizations, usually found at museums and science centers, into the classroom, where students can learn by exploring.
Spring came early this year, breaking several records at the top of the world in Barrow, Alaska, according to a new report that combines observations from NOAA, the North Slope Borough and a scientist who has tracked an Arctic bird for the last four decades.
New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build and maintain their shells by 2030, with the Bering Sea reaching this level of acidity by 2044.
Testing new scientific technology is a risky business. In the case of two Saildrones released in the eastern Bering Sea over a month ago, the risk has led to big rewards. Equipped with a suite of scientific sensors, the unmanned surface vehicles are performing beyond researchers’ expectations during their first test run in cold waters. Each Saildrone has collected over 40 million measurements over the course of the planned 2.5 month test mission.
It is too soon to know if recent extreme cold weather such as the last two East Coast winters are linked to Arctic climate warming, according to new research published in the Journal of Climate by James Overland of NOAA, and other authors from North America, Asia and Europe.
