Biological responses to change in Antarctic sea ice habitats
2023-12-31 (or before) in FrontiersSea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent and duration in coming decades. The sea-ice cover is instrumental in mediating ocean-atmosphere exchanges and provides an important substrate for organisms from microbes to predators. Antarctic krill, Euphausia superba, are reliant on sea ice during key phases of its life cycle, particularly during the larval stages, as feeding grounds and refuge from their predators, while other small grazers, including copepods and amphipods, either live in the brine channel system or find food and shelter at the ice-water interface and in raf...

The Antarctic ice sheet is melting and, yeah, it’s probably our fault.
2019-08-14 in RealClimateGlaciers in West Antarctica have thinned and accelerated in the last few decades. A new paper provides some of the first evidence that this is due to human activities. by Eric Steig It’s been some time since I wrote anything for RealClimate. In the interim there’s been a lot of important new work in the area of my primary research interest – Antarctica. Much of it is aimed at addressing the central ...

Oceans Are Melting Glaciers from Below Much Faster than Predicted, Study Finds - Inside Climate News
2019-07-25 in Inside Climate NewsBeneath the ocean’s surface, glaciers may be melting 10 to 100 times faster than previously believed, new research shows. Until now, scientists had a limited understanding of what happens under the water at the point where land-based glaciers meet the sea. Using a combination of radar, sonar and time-lapse photography, a team of researchers has […]
