location of the southern ocean on a map
Southern Ocean The Southern Ocean, also known as the Antarctic Ocean[1] or the Austral Ocean,[2][note 4] comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica.[6] As such, it is regarded as the fourth-largest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean.[7] This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters.
Western Hemisphere Below is a list of the countries which are in both the Western and Eastern Hemispheres along the 180th meridian, in order from north to south:
Borders of the oceans The Southern Ocean did not appear in the 1953 third edition because "...the northern limits ... are difficult to lay down owing to their seasonal change ... Hydrographic Offices who issue separate publications dealing with this area are therefore left to decide their own northern limits. (Great Britain uses the Latitude of 55Â° South)". Instead, in the IHO 1953 publication, the Atlantic, Indian and Pacific Oceans were extended southward, the Indian and Pacific Oceans (which had not previously touched pre 1953, as per the first and second editions) now abutted at the meridian of South East Cape, and the southern limits of the Great Australian Bight and the Tasman Sea were moved northwards.[16]
