Southern Ocean Water
Schematic depth-latitude diagram showing the major circulation and water masses of the Southern Ocean. The following water masses are highlighted: (1) Antarctic Bottom Water flowing along the abyssal ocean, (2) Circumpolar Deep Water upwelling into the Antarctic Divergence Zone, (3) Antarctic Intermediate Water in the temperature range 4-6°C, and (4) Subantarctic Mode Water in the upper ocean north of the Subantarctic Front (SAF).
Antarctic Ocean
The Antarctic Ocean, sometimes called the Southern Ocean, is the watery belt surrounding Antarctica. It includes the great polar embayments of the Weddell Sea and Ross Sea, and the deep circumpolar belt of ocean between 50 and 60°S and the southern fringes of the warmer oceans to the north. Its northern boundary is often taken as 30°S (see illustration). The Antarctic is a cold ocean, covered by sea ice during the winter from Antarctica's coast northward to approximately 60°S.

NASA study links El Nino and southern ocean changes
NASA researchers have found strong relationships between El Nino episodes and changes in climate and sea ice cover around Antarctica. Identifying these relationships is important because it provides new insights into the changing characteristics of the Antarctic region and their role in Earth's climate system.
