Mesoscale thermal structure of the polar front zone in Drake Passage during the austral summer of 1976
Vita. The boundary between the Subantarctic and Antarctic surface waters within the Southern Ocean is known as the Polar Front. This front lies within a complex transition region referred to as the Polar Front Zone (PFZ). The Polar Front and PFZ have been the subject of much interest and debate almo...
