The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
The deepest region of the ocean is at the Mariana Trench, located in the Pacific Ocean near the Northern Mariana Islands. The maximum depth has been estimated to be 10,971 meters (35,994 ft). The British naval vessel Challenger II surveyed the trench in 1951 and named the deepest part of the trench the " Challenger Deep ".

Though generally described as several separate oceans, the world's oceanic waters constitute one global, interconnected body of salt water sometimes referred to as the World Ocean or Global Ocean. This concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography. The major ocean...
The Arctic Ocean covers much of the Arctic and washes upon Northern America and Eurasia. It is sometimes considered a sea or estuaryof the Atlantic Ocean. The International Hydrographic Organization (IHO) defines the limits of the Arctic Ocean (excluding the seas it contains) as follows:: Art. 17 Note that these definitions exclude any marginal wat...

The Southern Ocean contains the waters that surround Antarcticaand sometimes is considered an extension of Pacific, Atlantic and Indian Oceans. In 1928, the first edition of the International Hydrographic Organization's (IHO) Limits of Oceans and Seas publication included the Southern Ocean around Antarctica. The Southern Ocean was delineated by la...
Scientific researchers have proposed the existence of a natural boundary between the Atlantic and Pacific oceans, existing the theory of natural delimitation between the Pacific and South Atlantic oceans by the Shackleton Fracture Zone and the theory of natural delimitation between the Pacific and South Atlantic oceans by the Scotia Arcthe former b...
The Pacific Ocean evolved in the Mesozoic from the Panthalassic Ocean, which had formed when Rodinia rifted apart around 750 Ma. The first ocean floor which is part of the current Pacific Plate began 160 Ma to the west of the central Pacific and subsequently developed into the largest oceanic plate on Earth.
Depending on the context, the term Pacific Islands may refer to one of several different concepts: (1) those countries and islands with common Austronesian origins, (2) the islands once (or currently) colonized, (3) the geographical region of Oceania, or (4) any island located in the Pacific Ocean.
