Dorsey Island

Dorsey Island (70°22′S 71°33′W / 70.367°S 71.55°W / -70.367; -71.55) is a mainly ice-covered island, 12 nautical miles (22 km) long, lying in Wilkins Sound off the west coast of Alexander Island. Discovered and roughly mapped from aircraft by members of East Base of the United States Antarctic Service (USAS), 1939–41, and named after Herbert G. Dorsey, Jr., of the U.S. Weather Bureau, meteorologist at East Base who devised a method of predicting with exceptional accuracy the periods in which weather would be suitable for flying. Remapped from air photos taken by Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. The position of the island and its outline were corrected from U.S. Landsat imagery of 1973-75 and 1979.
