Type	Phantom island

The Maria-Theresa Reef is a supposed reef in the South Pacific (south of French Tuamotu islands and east of New Zealand); it appears to be a phantom reef. It is also known as Tabor Island or Tabor Reef on French maps.

It was reported on 16 November 1843 by a Captain Asaph P. Taber (not "Tabor") of the Maria-Theresa, a New Bedford, Massachusetts, whaler, to be situated at 37°00′S 151°00′W / 37.000°S 151.000°W / -37.000; -151.000, later adjusted to 37°00′S 151°13′W / 37.000°S 151.217°W / -37.000; -151.217. It was unsuccessfully searched for in 1957. In 1983, the position of the reef was recalculated at 36°50′S 136°39′W / 36.833°S 136.650°W / -36.833; -136.650, more than 1,000 km further east, and searched for, but not found. Its existence is doubtful.
