Robertson Islands (Robertson, islas)
The Robertson Islands or Robertsons Islands are a group of islands extending 6 km southward of the south-eastern extremity of Coronation Island in the South Orkney Islands of Antarctica. They were discovered and roughly charted by Captains George Powell and Nathaniel Palmer in December 1821 and named by James Weddell in 1823.
The northern islands of the group (those north of Atriceps Island), including Matthews, Coffer, Steepholm and Skilling Islands with their associated islets and skerries, have been identified as an Important Bird Area (IBA) by BirdLife International because they support substantial breeding colonies, totalling about 35,000 pairs, of chinstrap penguins. Snow petrels also breed in the area of the Divide – the narrow channel separating Matthews from Coronation Island at the northern limit of the IBA.

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.
