Anvers Island, also known as Antwerp Island or Isla Amberes, is the largest island in the Palmer Archipelago. It was discovered in 1832 by John Biscoe and named in 1898 by Adrien de Gerlache, who ran the Belgian Antarctic Expedition. The Palmer Station on Anvers Island is one of three research stations in Antarctica operated by the United States Antarctic Program. The station is named for Nathaniel B. Palmer, believed to have been the first American to have seen Antarctica.
