Emerald Island (phantom)

It was first sighted by the British sealing ship Emerald, captained by William Elliot, in December 1821,[1] and the name of the supposed island is derived from the name of this ship.

[1][2] No trace of the island was found by the 1840 United States Exploring Expedition.

[3][4] Although a captain visiting Port Chalmers reported seeing it sometime before 1890,[2] a search by the Nimrod in 1909 turned up nothing.

[5] Nevertheless, it appeared on a map as late as 1987 in a desk calendar book (with atlas) published by American Express.

[citation needed] The abyssal plain on the ocean floor beneath the supposed location of this phantom island is named Emerald Basin.
