O'Brien Island is a small rock island with a maximum height of 540 m in the archipelago of the South Shetland Islands . It is located 3 km southwest of Aspland Island in the eastern archipelago called Islas Piloto Pardo by Chile .
The British navigator Edward Bransfield roughly mapped them on his Antarctic voyage between February and March 1820. Together with the islands later named Aspland Island and Eadie Island , they appeared on his map as O'Brien's Islands . Fabian Gottlieb von Bellingshausen named the group during his Antarctic voyage (1819-1821) in 1821 as Ostrowa Tri Brata ( German Three Brothers Islands ). The British sealer captain George Powell († 1823) named the island described here on his map from 1822 as O'Brien's Island . The name used today goes back to participants in the British Discovery Investigations , who mapped the island in February 1937.
