Mikkelsen Harbor
Mikkelsen Harbour () is a small bay indenting the south side of Trinity Island between Skottsberg Point and Borge Point, in the Palmer Archipelago, Antarctica. It provides excellent anchorage for ships, and was frequently used by sealing vessels in the first half of the nineteenth century and by Norwegian whaling vessels at the beginning of the twentieth century. History Mikkelsen Harbour was discovered by the Swedish Antarctic Expedition (SAE) of 1901–04. The origin of the name comes from Peder Michelsen, a whaling manager who was lost in the whaling grounds in December 1910. The harbour was charted by Captain Hans Borge. Apparently the name was in common usage by 1913, at the time of the geologic reconnaissance by Scottish geologist David Ferguson in the whale-catcher ''Hanka''.Whaling in the Falkland Island Dependencies 1904-1931 by Ian B.

Trinity Island
Trinity Island or Île de la Trinité or Isla Trinidad is an island long and wide in the northern part of the Palmer Archipelago, Antarctica. It lies east of Hoseason Island, south of Deception Island in the South Shetland Islands, and north-northwest of Cape Andreas on the Antarctic Peninsula. The island was named by Otto Nordenskiöld, leader of the 1901-1904 Swedish Antarctic Expedition (SAE) in commemoration of Edward Bransfield's "Trinity Land" of 1820. History Trinity Island, or the adjoining Davis Coast stretch of the Antarctic Peninsula, may have been the first part of Antarctica spotted by Nathaniel Palmer, on 16 November 1820. He was an American sealer, exploring southwards from Cape Horn in his little sloop searching for seal rookeries. The whole archipelago was named in his honour in 1897 by Adrien de Gerlache, leader of the Belgian Antarctic Expedition.

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica.
