<P> Based on the original 1928 IHO delineation of the Southern Ocean (and the 1937 delineation if the Great Australian Bight is considered integral), Australian ports and harbors between Cape Leeuwin and Cape Otway on the Australian mainland and along the west coast of Tasmania would also be identified as ports and harbors existing in the Southern Ocean . These would include the larger ports and harbors of Albany, Thevenard, Port Lincoln, Whyalla, Port Augusta, Port Adelaide, Portland, Warrnambool, and Macquarie Harbour . </P> <P> Yacht races have been held in the Southern Ocean, such as the Volvo Ocean Race, Velux 5 Oceans Race, Vendée Globe, Jules Verne Trophy and Global Challenge . </P>

When did the antarctic ocean become the southern ocean
