Dunbar Islands (Dunbar, islas)
The Dunbar Islands are a small group of islands lying off Varna Peninsula southwest of Williams Point, the northeast extremity of Livingston Island in the South Shetland Islands, Antarctica comprising the islands of Aspis, Balsha, Melyane, Pogledets and Zavala, and several minor islets and rocks. The area was visited by early 19th century sealers.
The islands are named after Captain Thomas Dunbar, Master of the American sealing schooner Free Gift which visited the South Shetland Islands in 1820–21.
The midpoint of the group is located at -62.46944°N, -60.17778°W (British mapping in 1968, Spanish in 1991, and Bulgarian in 2005 and 2009).

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.
