Best Answer

One reason was that the Southern Ocean had long been regarded as a separate ocean and the name change merely formalised it. Another reason was that the waters and currents of the Southern Ocean are distinct and differ greatly from the adjoining waters. There is still some controversy over the Southern Ocean, where the boundary should be and, if it should have been created at all.

As of the year 2000, the International Hydrographic Organisation decided that the waters surrounding Antarctica would be known officially as the Southern Ocean.

The Southern Ocean extends from the coast of Antarctica to the 60 degree South line of Latitude.

What is now the Southern Ocean was previously the southern most portions of the Atlantic, Pacific and Indian Oceans.

The Southern Ocean incorporates the Amundsen Sea, Bellingshausen Sea, part of the Drake Passage, Ross Sea, a small part of the Scotia Sea, Weddell Sea, and other tributary water bodies.
