Five oceanic divisions are usually recognized: Pacific, Atlantic, Indian, Arctic, and Southern/Antarctic; the last two listed are sometimes consolidated into the first three.
False color map of ocean depth in the Atlantic basin. The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S. [24]
The IHO limits of the Atlantic Ocean. This is a list of islands in the Atlantic Ocean, the largest of which is Greenland.Note that the definition of the ocean used by the International Hydrographic Organization (IHO) excludes the seas, gulfs, bays, etc., bordering the ocean itself. [1]

[5] It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the ...

To Magellan, it seemed much more calm (pacific) than the Atlantic. [83] The andesite line is the most significant regional distinction in the Pacific.
The Mediterranean Sea, between Africa and Europe The Atlantic Ocean around the plate boundaries (text is in Finnish). The African and European mainlands are non-contiguous, and the delineation between these continents is thus merely a question of which islands are to be associated with which continent.
The umbrella term Pacific Islands has taken on several meanings. [1] Sometimes it is used to refer only to the islands defined as lying within Oceania. [2] [3] [4] At other times, it is used to refer to the islands of the Pacific Ocean that were previously colonized by the British, French, Spaniards, Portuguese, Dutch, or Japanese, or by the United States.
