Biological responses to change in Antarctic sea ice habitats

  2023-12-31 (or before) in Frontiers

Sea 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...

Beneath 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 […]
