Steventon Island (Steventon Island)
Steventon Island (°N, °W) is a broad ice-covered island about 24 mi long off of Antarctica, lying west of Court Ridge in the Sulzberger Ice Shelf. It is 45 km (28 mi) long and 27 km (16.8 mi) wide, and covers an area of around 780 km2 (301 sq mi). It was mapped from surveys by the United States Geological Survey (USGS) and U.S. Navy air photos (1959–65), and named by the Advisory Committee on Antarctic Names (US-ACAN) for Richard F. Steventon, USN, Petty Officer in charge of Eights Station, 1963.

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.
