Martin Islands (Martín, islas)
The Martin Islands are a group of islands and rocks 5 nmi in extent lying 5 nautical miles east of the northern part of Renaud Island, and 1 nmi west of Vieugue Island in Grandidier Channel, Antarctica. A group of islands to the north of "Pitt Island" was roughly charted and named "Martin Islands" for Captain Martin of the Argentine Navy, by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot. Aerial surveys have shown that what appeared to be one large island, Pitt, is actually a group of small islands. As they lie in one group with no logical division between them, the earlier name of Pitt was amended to Pitt Islands and extended to cover all the islands north of Renaud Island. The name Martin Islands was transferred to the group now described in order to preserve Charcot's name in the area.

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.
