Signy Island (Signy, isla)
Signy Island is a small subantarctic island in the South Orkney Islands of Antarctica. It was named by the Norwegian whaler Petter Sørlle (1884–1933) after his wife, Signy Therese.

The island is about 6.5 km long and 5 km wide and rises to 288 m above sea level. Much of it is permanently covered with ice. The average temperature range is 0 °C to about -10 °C in winter (i.e. in July). The extremes extend to 12 and -44 °C. It is separated from Coronation Island to the north by Normanna Strait, and from Moe Island to the southwest by Fyr Channel.

On Signy Island, the British Antarctic Survey (BAS) maintains the Signy Research Station, a scientific station for research in biology. The base was opened on 18 March 1947, on the site of an earlier whaling station that had existed there in the 1920s. The station was staffed year-round until 1996; since that year it has been occupied only from November to April. It houses 10 people.

A number of locations on the island have been charted and individually named by various Antarctic expeditions. The first survey was conducted in 1912 by Norwegian whaling captain Petter Sørlle. It was subsequently visited and charted by Discovery Investigations (DI) personnel in 1927 and 1933. Finally, in 1947, the Falkland Islands Dependencies Survey (FIDS) charted the island. The charts produced by these surveys account for many of the names of the island's features. Others were provided later by the UK Antarctic Place-Names Committee (UK-APC).

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.
