SCORESBY, WILLIAM

born Oct. 5, 1789, Cropton, near Whitby, Yorkshire, Eng. died March 21, 1857, Torquay, Devon English explorer, scientist, and clergyman who pioneered in the scientific study of the Arctic and contributed to the knowledge of terrestrial magnetism. At the age of 10 Scoresby made his first Arctic whaling voyage aboard his father's ship, the Resolution, which he later commanded in 1811. In 1813 he established that the temperature of polar waters is warmer at great depths than at the surface. His Account of the Arctic Regions with a History and Description of the Northern Whale-Fishery (1820) contained his own findings as well as those of earlier navigators. His voyage to Greenland in 1822, during which he surveyed 400 miles (650 kilometres) of the east coast, was his last venture into the Arctic. He then began divinity studies at Cambridge and later became a clergyman. His new career did not, however, end his scientific work. In 1848, while crossing the Atlantic, he made valuable observations on the height of waves. He also voyaged to Australia in 1856 to gather data on the Earth's magnetism.
