BackgroundAn island reportedly last seen in 1893 about 70 km NNE of Bouvet Island was gone in 1898, possibly as a result of an undetected volcanic eruption (Baker, 1967).
The location for the island given by Norris in 1825 appears unlikely. Bathymetry at the reported location of the island shows a depth of more than 2400 m (Smith and Sandwell, 1997), and the exact location of the possible former island and the confirmation of the existence of a submarine volcano remains uncertain. Thompson Island was not mentioned in a LeMasurier and Thomson (1990) compilation of volcanoes of the Antarctic Plate and the southern oceans, for which Baker was an associate editor.
