"Southern Ocean" as alternative to the Aethiopian Ocean, 18th century "Southern Ocean" is an obsolete name for the Pacific Ocean or South Pacific, coined by the Spanish explorer Vasco Núñez de Balboa, the first European to discover the Pacific, who approached it from the north in Panama. [24] The "South Seas" is a less archaic synonym.
The project aims to identify and pool all Bathymetry data in the Southern Ocean and use that data to produce gridded bathymetric maps of the seafloor. The extent of the project is bound by 50°S, stretching from the southern tip of South America to the coastal waters of Antarctica.
Maps exhibiting the world's oceanic waters. A continuous body of water encircling Earth, the World/Global Ocean is divided into a number of principal areas. Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...

National Geographic announced it was recognizing the body of water encircling the Antarctic as the Earth's fifth ocean: the Southern Ocean.
The Weddell Sea is part of the Southern Ocean and contains the Weddell Gyre. Its land boundaries are defined by the bay formed from the coasts of Coats Land and the Antarctic Peninsula. The easternmost point is Cape Norvegia at Princess Martha Coast, Queen Maud Land. To the east of Cape Norvegia is the King Haakon VII Sea.
Trenches were not clearly defined until the late 1940s and 1950s. The bathymetry of the ocean was poorly known prior to the Challenger expedition of 1872–1876, [12] which took 492 soundings of the deep ocean. [13] At station #225, the expedition discovered Challenger Deep, [14] now known to be the southern end of the Mariana Trench.
