Roca Islands (Roca, islotes)
Roca Islands (-65.18333°N, -64.45°W) is a group of small islands between Cruls Islands and Anagram Islands on the south side of French Passage in the Wilhelm Archipelago. Discovered by the French Antarctic Expedition, 1903–05, and named by Charcot for Julio A. Roca, President of Argentina, 1880–86 and 1898–1904. The name was incorrectly applied to the Anagram Islands by the British Graham Land Expedition (BGLE), 1934–37, but was reidentified with this group after further mapping by the British Naval Hydrographic Survey Unit in 1958.

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.
