Radford Island (Radford Island)
Radford Island (-76.9°N, -146.6°W) is an ice-covered island surmounted by several peaks, lying 6 nautical miles (11 km) west of Saunders Mountain in the east part of Sulzberger Ice Shelf. Discovered by the Byrd Antarctic Expedition on the Eastern Flight of 5 December 1929. This feature was mapped as a part of the mainland by the United States Antarctic Service (USAS) (1939–1941) and named "Radford Mountains." It was determined to be an island by the U.S. Geological Survey from air photos taken by the U.S. Navy, 1962–1965. Named by Byrd for V. Admiral Arthur W. Radford, U.S. Navy, Deputy Chief of Naval Operations (Air) during the exploration by U.S. Navy Operation Highjump (1946–1947) and later Admiral and Chairman of the Joint Chiefs of Staff.

Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14200000 km2. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km.
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 m. Antarctica holds the record for the lowest measured temperature on Earth, −89.2 C. The coastal regions can reach temperatures over 10 C in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss.
