Ross Dependency

The Ross Dependency is a region of Antarctica defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south. It is claimed by New Zealand. Since the Antarctic Treaty came into force in 1961, Article IV of which states "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". Most countries do not recognise territorial claims in Antarctica. The Dependency takes its name from Sir James Clark Ross, who discovered the Ross Sea, and includes part of Victoria Land, and most of the Ross Ice Shelf. Ross Island, Balleny Islands and the small Scott Island also form part of the Dependency, as does the ice-covered Roosevelt Island.
