Background | The Pacific Ocean is the largest of the world's five oceans (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 decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth ocean, the Southern Ocean, removed the portion of the Pacific Ocean south of 60 degrees south. | This archipelago - surrounded by rich fishing grounds and potentially by gas and oil deposits - is claimed in its entirety by China, Taiwan, and Vietnam, while portions are claimed by Malaysia and the Philippines. All five parties occupy certain islands or reefs. |
Climate | planetary air pressure systems and resultant wind patterns exhibit remarkable uniformity in the south and east; trade winds and westerly winds are well-developed patterns, modified by seasonal fluctuations; tropical cyclones (hurricanes) may form south of Mexico from June to October and affect Mexico and Central America; continental influences cause climatic uniformity to be much less pronounced in the eastern and western regions at the same latitude in the North Pacific Ocean; the western Pacific is monsoonal - a rainy season occurs during the summer months, when moisture-laden winds blow from the ocean over the land, and a dry season during the winter months, when dry winds blow from the Asian landmass back to the ocean; tropical cyclones (typhoons) may strike southeast and east Asia from May to December | tropical |

Disputes - international | some maritime disputes (see littoral states) | all of the Spratly Islands are claimed by China, Taiwan, and Vietnam; parts of them are claimed by Malaysia and the Philippines; in 1984, Brunei established an exclusive fishing zone that encompasses Louisa Reef in the southern Spratly Islands, but has not publicly claimed the island; in 2000, China joined ASEAN discussions towards creating a South China Sea "code of conduct" - a non-legally binding confidence building measure |
Economy - overview | The Pacific Ocean is a major contributor to the world economy and particularly to those nations its waters directly touch. It provides low-cost sea transportation between East and West, extensive fishing grounds, offshore oil and gas fields, minerals, and sand and gravel for the construction industry. In 1996, over 60% of the world's fish catch came from the Pacific Ocean. Exploitation of offshore oil and gas reserves is playing an ever-increasing role in the energy supplies of the US, Australia, NZ, China, and Peru. The high cost of recovering offshore oil and gas, combined with the wide swings in world prices for oil since 1985, has led to fluctuations in new drillings. | Economic activity is limited to commercial fishing. The proximity to nearby oil- and gas-producing sedimentary basins suggests the potential for oil and gas deposits, but the region is largely unexplored, and there are no reliable estimates of potential reserves; commercial exploitation has yet to be developed. |

Maritime claims | - | NA |
Military - note | - | Spratly Islands consist of more than 100 small islands or reefs, of which about 45 are claimed and occupied by China, Malaysia, the Philippines, Taiwan, and Vietnam |
Natural hazards | surrounded by a zone of violent volcanic and earthquake activity sometimes referred to as the "Pacific Ring of Fire"; subject to tropical cyclones (typhoons) in southeast and east Asia from May to December (most frequent from July to October); tropical cyclones (hurricanes) may form south of Mexico and strike Central America and Mexico from June to October (most common in August and September); cyclical El Nino/La Nina phenomenon occurs in the equatorial Pacific, influencing weather in the Western Hemisphere and the western Pacific; ships subject to superstructure icing in extreme north from October to May; persistent fog in the northern Pacific can be a maritime hazard from June to December | typhoons; serious maritime hazard because of numerous reefs and shoals |
Natural resources | oil and gas fields, polymetallic nodules, sand and gravel aggregates, placer deposits, fish | fish, guano, undetermined oil and natural gas potential |
Population | - | no indigenous inhabitants
note: there are scattered garrisons occupied by personnel of several claimant states (July 2002 est.) |

Terrain | surface currents in the northern Pacific are dominated by a clockwise, warm-water gyre (broad circular system of currents) and in the southern Pacific by a counterclockwise, cool-water gyre; in the northern Pacific, sea ice forms in the Bering Sea and Sea of Okhotsk in winter; in the southern Pacific, sea ice from Antarctica reaches its northernmost extent in October; the ocean floor in the eastern Pacific is dominated by the East Pacific Rise, while the western Pacific is dissected by deep trenches, including the Mariana Trench, which is the world's deepest | flat |
