Thompson Island (South Atlantic)

Thompson Island is a phantom island in the South Atlantic. According to the Global Volcanism Program of the Smithsonian Institution, it was supposed to be about 70 km NNE of Bouvet Island, a small Norwegian dependency located between South Africa and Antarctica. Thompson Island was first reported and named by whaler captain George Norris in 1825. It was last reported seen in 1893; however, when the German survey ship Valdivia finally fixed the position of Bouvet in 1898, they looked for Thompson, but did not find it. If Thompson ever existed, it is probable that it disappeared in a volcanic eruption sometime in the 1890s.
