Zoning of waters in the Australian-New Zealand sector of the South Ocean by the example of distribution of pelagic ostracods from subclass Myodocopa

Abstract

Distribution of mass antarctic, subantarctic, antarctic-subantarctic and tropical-subtropical interzonal pelagic ostracods is considered depending on structure and dynamics of waters in the Australian-New Zealand sector of the South Ocean on the base of authors’ and cited data. The species are separated latitudelly and vertically, that probably diminishes competition between them. Biogeographic boundaries of the subantarctic and antarctic zones determined by the ostracods distribution patterns are close to the South Polar and Subpolar Fronts.
