Nimrod Islands
The Nimrod Islands were a group of islands first reported in 1828 by Captain Eilbeck of the ship Nimrod while sailing from Port Jackson around Cape Horn. Their reported location was east of Emerald Island and west of Dougherty Island, at approximately . They are now considered phantom islands. The explorer John Biscoe in the brig Tula searched for the Nimrod Group without success in 1831 during the Southern Ocean Expedition. John King Davis, sailing aboard a different Nimrod, searched the location in June 1909 following Shackleton's famous Nimrod Expedition to Antarctica, and the Norwegian vessel Norvegia outfitted by Lars Christensen searched again in 1930; both expeditions reported empty seas. Captain J.P. Ault of the magnetic survey vessel Carnegie attempted to approach the location in December 1915 but was deterred by weather. See also
