Antarctic ice sheet
The Antarctic ice sheet, also called the Antarctic ice cap, is the ice mass covering almost all of Antarctica, holding about 58 meters of potential sea level rise.
Antarctic Intermediate Water
Antarctic Intermediate Water (AAIW) is a cold, low-salinity water mass of the Southern Ocean, marked by a salinity minimum at 700–1000 m that spreads northward into all three ocean basins.
Antarctic krill
Antarctic krill (Euphausia superba) is a swarming Southern Ocean crustacean, the largest biomass of any multicellular wild animal species at 300–500 million tonnes, keystone prey for whales, penguins and seals, and target of the CCAMLR-managed krill fishery.
