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]
In response to the need for a new route to Asia, by the 1480s, Christopher and his brother Bartholomew had developed a plan to travel to the Indies (then construed roughly as all of southern and eastern Asia) by sailing directly west across what was believed to be the singular "Ocean Sea," the Atlantic Ocean.
The principal divisions (in descending order of area) are the: Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean. Smaller regions of the oceans are called seas, gulfs, bays, straits, and other terms. Geologically, an ocean is an area of oceanic crust covered by water.
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] Thus, for instance, not all of the islands of the United Kingdom are actually in or bordering on the Atlantic. For reference, islands in gulfs and seas are included in a separate ...

Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name (see: Borders of the oceans for details). Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...
The Sargasso Sea (/ s ɑːr ˈ ɡ æ s oʊ /) is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. [1] Unlike all other regions called seas, it has no land boundaries. [2] [3] It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water. [1]

Atlantic history is a specialty field in history that studies the Atlantic World in the early modern period.
