Antarctic Ocean (Southern Ocean) Term used to describe the oceanic waters surrounding Antarctica. It extends northwards to about 40°S latitude, the limit of the northward drift of ice from the Antarctic region, where there is a marked change in water temperature and salinity. The Antarctic Ocean is typified by low water temperatures (−1.8°C to 10°C).
