:"This article is about the body of water. For other uses, see
SEAand seas. For the ancient Jewish unit of volume, see Seah (unit). For the Smirnoffadvertising campaign, see Sea (Smirnoff advert)"The term sea refers to certain large bodies of water, but there is inconsistency as to its precise definition and application. Most commonly, a sea may refer to a large expanse of saline water connected with an ocean, but it is also used sometimes of a large saline lakethat lacks a natural outlet, e.g. the Aral Sea. Colloquially, the term is used as a synonym for ocean. Additionally, large lakes, such as the Great Lakes, are occasionally referred to as inland seas.
International Hydrographic Organization
International Hydrographic Organization(IHO) is the international authority that sets forth nomenclatureand definition of bodies of water. [cite web | author= | title=IHO Background Information | url=http://www.iho.shom.fr/gen_info/background.htm | publisher=International Hydrographic Organization | date=25 August 2004 | accessdate=2008-05-17] The IHO's "Limits of Oceans and Seas" was first published in 1928, with its current working document the third edition published in 1953. [cite paper | author=International Hydrographic Conference of 1952 | title=Limits of Oceans and Seas: Special publication S-23 | version=Third edition | format=.PDF | publisher=International Hydrographic Organization | url=http://www.iho.shom.fr/publicat/free/files/S23_1953.pdf | date=1953 | accessdate=2008-05-17] A fourth draft edition was proposed in 1986 but has yet to be ratified due to outstanding issues such as the Sea of Japan naming dispute.
