Southern Ocean

Introduction to Southern Ocean

A decision by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude, which coincides with the Antarctic Treaty Limit. The Southern Ocean is now the fourth largest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).

Economy overview:

Fisheries in 2000-01 (1 July to 30 June) landed 112,934 metric tons, of which 87% was krill and 11% Patagonian toothfish. International agreements were adopted in late 1999 to reduce illegal, unreported, and unregulated fishing, which in the 2000-01 season landed, by one estimate, 8,376 metric tons of Patagonian and antarctic toothfish. In the 2000-01 antarctic summer 12,248 tourists, most of them seaborne, visited the Southern Ocean and Antarctica, compared to 14,762 the previous year.
