List of seas


This is a list of seas – large divisions of the World Ocean, including areas of water, variously gulfs, bights, bays, and straits.

Terminology

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:
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.

Marginal seas

Sources differ over which seas are considered marginal seas as well as which ocean a given sea is considered a marginal part of. There is no single ultimate authority on the matter.

[Atlantic Ocean]

In addition to the marginal seas listed in the three sub-sections below, the Arctic Ocean itself is sometimes also considered a marginal sea of the Atlantic.
