Terminology

* Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name. See

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. *

– 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.
