<P> In 1928, the first edition of the International Hydrographic Organization's (IHO) Limits of Oceans and Seas publication included the Southern Ocean around Antarctica . The Southern Ocean was delineated by land - based limits - the continent of Antarctica to the south, and the continents of South America, Africa, and Australia plus Broughton Island, New Zealand in the north . The detailed land - limits used were Cape Horn in South America, Cape Agulhas in Africa, the southern coast of Australia from Cape Leeuwin, Western Australia, to South East Cape, Tasmania, via the western edge of the water body of Bass Strait, and then Broughton Island before returning to Cape Horn . </P> <P> The northern limits of the Southern Ocean were moved southwards in the IHO's 1937 second edition of the Limits of Oceans and Seas . The Southern Ocean then extended from Antarctica northwards to latitude 40 ° south between Cape Agulhas in Africa (long . 20 ° east) and Cape Leeuwin in Western Australia (long . 115 ° east), and extended to latitude 55 ° south between Auckland Island of New Zealand (long . 165 ° or 166 ° east) and Cape Horn in South America (long . 67 ° west). </P> <P> 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 55 ° 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 . </P> <P> The IHO readdressed the question of the Southern Ocean in a survey in 2000 . Of its 68 member nations, 28 responded, and all responding members except Argentina agreed to redefine the ocean, reflecting the importance placed by oceanographers on ocean currents . The proposal for the name Southern Ocean won 18 votes, beating the alternative Antarctic Ocean . Half of the votes supported a definition of the ocean's northern limit at 60 ° S (with no land interruptions at this latitude), with the other 14 votes cast for other definitions, mostly 50 ° S, but a few for as far north as 35 ° S . </P>

Where do the indian and pacific oceans meet
