Background:
The Pacific Ocean is the largest of the world's five ocean basins (followed by the Atlantic Ocean, Indian Ocean, Southern Ocean, and Arctic Ocean). Strategically important access waterways include the La Perouse, Tsugaru, Tsushima, Taiwan, Singapore, and Torres Straits. The International Hydrographic Organization decision in 2000 to delimit a fifth world ocean basin, the Southern Ocean, removed the portion of the Pacific Ocean south of 60 degrees south. For convenience and because of its immense size, the Pacific Ocean is often divided at the Equator and designated as the North Pacific Ocean and the South Pacific Ocean.
