Pacific Ocean (Oceans)


Introduction :: Pacific Ocean

Background: This entry usually highlights major historic events and current issues and may include a statement about one or two key future trends. Background field listing
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.

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
Terrain: This entry contains a brief description of the topography. Terrain field listing

Environment - current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry: Acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain).

Economy :: Pacific Ocean

Economy - overview: This entry briefly describes the type of economy, including the degree of market orientation, the level of economic development, the most important natural resources, and the unique areas of specialization. It also characterizes major economic events and policy changes in the most recent 12 months and may include a statement about one or two key future macroeconomic trends. Economy - overview field listing
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.
Marine fisheries: This entry describes the major fisheries in the world's oceans in terms of the area covered, their ranking in terms of the global catch, the main producing countries, and the principal species caught. Information provided by the Fisheries and Aquaculture Department of the UN Food and Agriculture Organization (FAO). Marine fisheries field listing

the International Maritime Bureau reports the territorial waters of littoral states and offshore waters in the South China Sea as high risk for piracy and armed robbery against ships; an emerging threat area lies in the Celebes and Sulu Seas between the Philippines and Malaysia where three crew were kidnapped or taken hostage in 2018; numerous commercial vessels have been attacked and hijacked both at anchor and while underway; hijacked vessels are often disguised and cargoes stolen; crew and passengers are often held for ransom, murdered, or cast adrift; the Maritime Administration (MARAD) of the US Department of Transportation has issued a Maritime Advisory (2019-011-Sulu and Celebes Seas-Piracy/Armed Robbery/Terrorism) which states in part "In 2018, there were at least 12 reported boardings, attempted boardings, attacks, hijackings, and kidnappings in the Sulu and Celebes Seas. Recent kidnapping incidents in this area were reportedly linked to the Abu Sayyaf Group (ASG), a violent Islamic separatist group operating in the southern Philippines..." and advises ships to adhere to counter-piracy practices to minimize risk
