Islands

The area closely surrounding the Antarctic Peninsula is particularly rich in islands including the South Orkney Islands and the South Shetland Islands. In Bransfield Strait lies Deception Island, the horseshoe-shaped summit of a mostly submerged volcano where two eruptions in the 19th century destroyed scientific stations. The Balleny Islands are located outside the Ross Sea. Roosevelt Island lies in the Ross Sea Ice Shelf and Berkner Island is located in the Filchner-Ronne Ice Shelf.
