<Li> <P> Los Molinos on the coast of Southern Chile </P> </Li> <P> Los Molinos on the coast of Southern Chile </P> <P> The volume of the Pacific Ocean, representing about 50.1 percent of the world's oceanic water, has been estimated at some 714 million cubic kilometers (171 million cubic miles). Surface water temperatures in the Pacific can vary from − 1.4 ° C (29.5 ° F), the freezing point of sea water, in the poleward areas to about 30 ° C (86 ° F) near the equator . Salinity also varies latitudinally, reaching a maximum of 37 parts per thousand in the southeastern area . The water near the equator, which can have a salinity as low as 34 parts per thousand, is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year . The lowest counts of less than 32 parts per thousand are found in the far north as less evaporation of seawater takes place in these frigid areas . The motion of Pacific waters is generally clockwise in the Northern Hemisphere (the North Pacific gyre) and counter-clockwise in the Southern Hemisphere . The North Equatorial Current, driven westward along latitude 15 ° N by the trade winds, turns north near the Philippines to become the warm Japan or Kuroshio Current . </P> <P> Turning eastward at about 45 ° N, the Kuroshio forks and some water moves northward as the Aleutian Current, while the rest turns southward to rejoin the North Equatorial Current . The Aleutian Current branches as it approaches North America and forms the base of a counter-clockwise circulation in the Bering Sea . Its southern arm becomes the chilled slow, south - flowing California Current . The South Equatorial Current, flowing west along the equator, swings southward east of New Guinea, turns east at about 50 ° S, and joins the main westerly circulation of the South Pacific, which includes the Earth - circling Antarctic Circumpolar Current . As it approaches the Chilean coast, the South Equatorial Current divides; one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current . </P>
