The Antarctic Zone (AZ), in oceanography, is the region in the Southern Ocean between the Polar Front to the north and the Southern Antarctic Circumpolar Current Front to the south. The AZ is one of four distinct surface water mass regimes in the Southern Ocean, the others being the Continental Zone (CZ) to the south and the Polar Frontal Zone (PFZ) and Subantarctic Zone (SAZ) to the north.
In more general usage the Antarctic Zone is often taken to be the section of the earth's surface lying between the Antarctic Circle and the South Pole.
