Ranvik Island (Ranvik Island)
Ranvik Island (-68.9°N, 77.83333°W) is a rocky island, 1.5 nautical miles (2.8 km) long, which is the largest island in the southern part of the Rauer Islands. It lies at the northern end of Ranvik Bay, about 3 nautical miles (6 km) northwest of Browns Glacier. Mapped by Norwegian cartographers, as being connected to the mainland, from air photos taken by the Lars Christensen Expedition (1936–37). They gave the name "Ranviktangen" (the Ranvik tongue) because of its association with Ranvik Bay. The Advisory Committee on Antarctic Names (US-ACAN) has approved John H. Roscoe's 1952 recommendation that the Norwegian name be amended to Ranvik Island. Roscoe's examination of this area in air photos taken by U.S. Navy Operation Highjump (1946–47) determined that the feature described is actually separated from the mainland.

Country - Antarctica
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.
