The Larsen Islands are a small group of islands north-west of Moreton Point, the western extremity of Coronation Island, in the South Orkney Islands of Antarctica. They were discovered by Captains George Powell and Nathaniel Palmer on the occasion of their joint cruise in December 1821. The islands were named on Petter Sørlle's chart, based upon his survey of the South Orkney Islands in 1912–1913, in honour of Carl Anton Larsen.[1]
The islands were recharted in 1933 by Discovery Investigations (DI) personnel on the Discovery II, who used the name Larsen Islands for the group and named the largest island Larsen Island. This scheme was found to be confusing, so Larsen Island was renamed in 1954 by the UK Antarctic Place-names Committee (UK-APC) for the sloop James Monroe, which was commanded by Captain Palmer at the time of discovery and anchored in this vicinity in December 1821.[2]
