International Hydrographic Organization
The International Hydrographic Organization (IHO) is the international authority that sets forth nomenclature and definition of bodies of water. The IHO's Limits of Oceans and Seas was first published in 1928, with its current working document the third edition published in 1953. 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.The term "sea" has also been used in quantum physics. Dirac sea is an interpretation of the negative energy states that comprises the vacuum.
