Antarctic sea ice loss batters ocean’s freshwater engine
The Antarctic Intermediate Water (AAIW) – a vast layer of fresh water spanning much of the Southern Hemisphere’s ocean – has rapidly reversed its long-term trends in salinity and density, according to new research. The AAIW helps store carbon, supply oxygen and drive global ocean currents.
Scientists discover Arctic sea ice loss could be far worse than predicted
Arctic winter sea ice could disappear much faster than scientists previously expected, according to new research using climate clues from 6,000 years ago. By comparing ancient ocean sediments with modern climate models, researchers found that future winter ice coverage may be roughly one million square kilometers smaller than earlier predictions suggested.

An unprecedented gap in Antarctic sea ice.
A research station has begun drifting with Arctic sea ice. Here’s why scientists put it there.
By Lee Karp-BossProfessor, School of Marine Sciences, University of Maine A new research station has begun drifting with sea ice in the high Arctic, marking the start of an ambitious international effort to study one of the fastest-changing and least-understood regions on Earth. On Sept. 9, Tara Polar Station reached…
Engineers solve puzzle of Arctic sea ice movement
UC Riverside researchers discover a way to explain the previously confusing movement of Arctic sea ice, offering a way to potentially predict where the ice will travel as the ocean gets warmer.
