The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
World map of the five-ocean model with approximate boundaries. This list of countries which border two or more oceans includes both sovereign states and dependencies, provided the same contiguous territory borders on more than one of the five named oceans, the Pacific, Atlantic, Indian, Southern, and Arctic.

The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic. The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere and is thereby essential to life on Earth.
The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60° north latitude, or the region from the North Pole south to the timberline. [1] The Antarctic is usually defined simply as south of 60° south latitude, or the
The Antarctic Convergence is a zone approximately 32 to 48 km (20 to 30 mi) wide, varying in latitude seasonally and in different longitudes, extending across the Atlantic, Pacific, and Indian oceans between the 48th and 61st parallels of south latitude. Although the northern boundary varies, for the purposes of the Convention on the ...
[10] [11] It includes the Pacific, Atlantic, Indian, Southern/Antarctic, and Arctic oceans. [19] As a general term, "the ocean" and "the sea" are often interchangeable. [20] Strictly speaking, a "sea" is a body of water (generally a division of the world ocean) partly or fully enclosed by land. [21]
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 the 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 final elaboration of this thesis is in a 1952 work of the Chilean admiral Rafael Santibáñez Escobar. [2] It was based on scientific studies that showed a correlation between the characteristics of the waters of the southeastern Pacific Ocean and those bounded by the Scotia Arc to the east and the Drake Passage to the west, an area known as the Scotia Sea and sometimes also as the Austral ...
