Antarctic Circumpolar Water (AACW) is a type of water in the seas surrounding Antarctica with temperatures ranging from zero to 0.8 degrees C, salinities from 34.6 to 34.7 ppt, and a depth range from a few hundred meters (m) to about 1000-2000 m [3000 m (Tchernia)] The AACW is formed from a mixture of overlying North Atlantic Deep Water (NADW) and underlying (at 1000-2000 m) Antarctic Bottom Water (AABW). It has a temperature maximum at around 500-600 m and a salinity maximum between 700-1300 m in depth. This was originally called Warm Deep Water (WDW) by Deacon, but renamed AACW by Sverdrup.
