Antarctic intermediate water
From AMS Glossary
Antarctic Intermediate Water
A water mass identified by a salinity minimum found at depths between 700 and 1000 m in the Southern Hemisphere.
It is formed at various locations along the Antarctic Polar Front and through deep winter convection east of southern Chile and south of the Great Australian Bight. It enters all oceans with the Antarctic Circumpolar Current and spreads toward the equator between the central water and the deep water.
