Sheehan Islands
Sheehan Islands is a group of small islands lying at the southeast side of Islay in the William Scoresby Archipelago. Discovered on February 18, 1931, by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Mawson. He named one of the group Sheehan Nunatak after Sir Harry Sheehan, Asst. Secretary to the Treasury, who was Secretary of the Australian Antarctic Committee of BANZARE. BANZARE erroneously charted Sheehan Nunatak as lying behind the coastline. The insularity of the group was determined by Discovery Investigations personnel on the RSS William Scoresby on February 27, 1936. The islands were more fully mapped by Norwegian cartographers from aerial photographs taken by the Lars Christensen Expedition in January and February 1937.
