This is a list of seas of the World Ocean, including marginal seas, areas of water, various gulfs, bights, bays, and straits.

Terminology

* 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 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 ...

for details. * Sea has several definitions: ** A marginal sea is a division of an ocean, partially enclosed by islands, archipelagos, or

peninsula A peninsula (; ) is a landform that extends from a mainland and is surrounded by water on most, but not all of its borders. A peninsula is also sometimes defined as a piece of land bordered by water on three of its sides. Peninsulas exist on all ...

s, adjacent to or widely open to the open ocean at the surface, and/or bounded by submarine ridges on the sea floor. ** A division of an ocean, delineated by landforms, currents (e.g.,

Sargasso Sea The Sargasso Sea () is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. Unlike all other regions called seas, it has no land boundaries. It is distinguished from other parts of the Atlantic Ocean by its charac ...

), or specific latitude or longitude boundaries. This includes but is not limited to marginal seas, and this is the definition used for inclusion in this list. ** The World Ocean. For example, the Law of the Sea states that all of the World Ocean is "sea", and this is also common usage for "the sea". ** Any large body of water with "Sea" in the name, including lakes. * River – a narrow strip of water that flows over land from a higher elevation to a lower one * Tributary – a small river that flows into a larger one * Estuary – the piece of a river that flows into the sea or ocean *

Strait A strait is an oceanic landform connecting two seas or two other large areas of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly, it is a narrow ocean channe ...

– a narrow area of water connecting two wider areas of water, also sometimes known as a passage *

Channel Channel, channels, channeling, etc., may refer to: Geography * Channel (geography), in physical geography, a landform consisting of the outline (banks) of the path of a narrow body of water. Australia * Channel Country, region of outback Austral ...

– usually wider than a strait * Passage – connects waters between islands, also sometimes known as a strait * Canal – a man-made channel * Fjard – a large open water between groups of islands There are several terms used for bulges of ocean that result from indentations of land, which overlap in definition, and which are not consistently differentiated: *

Bay A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay. A large bay is usually called a Gulf (geography), gulf, sea, sound (geography), sound, or bight (geogra ...

– generic term; though most features with "Bay" in the name are small, some are very large * Gulf – a very large bay, often a top-level division of an ocean or sea * Fjord – a long bay with steep sides, typically formed by a glacier * Bight – a bay that is typically shallower than a sound * Sound – a large, wide bay which is typically deeper than a bight, or a strait * Cove – a small, typically sheltered bay with a relatively narrow entrance *

Inlet An inlet is a (usually long and narrow) indentation of a shoreline, such as a small arm, bay, sound, fjord, lagoon or marsh, that leads to an enclosed larger body of water such as a lake, estuary, gulf or marginal sea. Overview In marine geogra ...

– a narrow and long bay similar to a land peninsula, but adjoining the sea * Polynya – least used of these terms, a patch of water surrounded by ice Many features could be considered to be more than one of these, and all of these terms are used in place names inconsistently; especially bays, gulfs, and bights, which can be very large or very small. This list includes large areas of water no matter the term used in the name.
