Buss is a ghost island that appears on maps of the North Atlantic. It was declared open during the third expedition of Martin Frobisher in September 1578 by sailors from the Emmanuel, portrayed on maps between Ireland and the island of Friesland (also subsequently turned out to be a ghost island), at about 57 degrees north latitude. The island was named after the discovery ship ( busse ). It is believed that Frobisher mistakenly mistook Greenland for Friesland, and Baffin Land for Greenland, and Emmanuel, returning home, made a mistake due to optical illusion in poor visibility conditions, being near Greenland at about 62 degrees north latitude.
In 1671, Thomas Shepard stated that he had explored the island and mapped it. When they began to swim more in the North Atlantic, the existence of the island became less defined, and its estimated size greatly decreased. In 1745 it was suggested that the island “drowned”, as its alleged location was deserted. An island or "place of a sunken island" could be found even on maps of the 19th century. Its existence was finally refuted by the English traveler John Ross during his first Arctic expedition of 1818 on the Isabella, when he did not find any land there, even at a depth of 180 fathoms (330 m).
