The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, bounded by Asia and Australia in the west, and the Americas in the east.
At 165.2 million square kilometres (64.1 million square miles) in area, this largest division of the World Ocean – and, in turn, the hydrosphere – covers about 46% of the Earth's water surface and about one-third of its total surface area, making it larger than all of the Earth's land area combined. The equator subdivides it into the North Pacific Ocean and South Pacific Ocean, with two exceptions: the Galápagos and Gilbert Islands, while straddling the equator, are deemed wholly within the South Pacific. The Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres (35,797 ft).
The eastern Pacific Ocean was first sighted by Europeans early in the 16th century. Spanish explorer Vasco Núñez de Balboa crossed the Isthmus of Panama in 1513 and named it Mar del Sur (South Sea). The ocean's current name was given by Portuguese explorer Ferdinand Magellan during the Spanish expedition of world circumnavigation in 1521, who encountered favourable winds as he reached the ocean and called it Mar Pacifico in Portuguese, meaning "peaceful sea".
Asia-Pacific or Asia Pacific (abbreviated as Asia-Pac, Asia Pac, AsPac, Aspac, Apac, APAC, APNIC, APJ, JAPA or JAPAC) is the part of the world in or near the Western Pacific Ocean. The region varies in size depending on context, but it typically includes at least much of East Asia, Southeast Asia, and Oceania.
The term may also include Russia (on the North Pacific) and countries in North and South America which are on the coast of the Eastern Pacific Ocean; the Asia-Pacific Economic Cooperation, for example, includes Canada, Chile, Russia, Mexico, Peru, and the United States.
Alternatively, the term sometimes comprises all of Asia and Australasia as well as small/medium/large Pacific island nations - for example when dividing the world into large regions for commercial purposes (e.g. into Americas, EMEA and Asia Pacific).
Even though imprecise, the term has become popular since the late 1980s in commerce, finance and politics[citation needed] though the economies within the region are heterogeneous, they are mostly emerging markets experiencing rapid growth. (Compare the concept/acronym APEJ or APeJ - Asia-Pacific excluding Japan.)
