Gamma Island (Observatorio, isla)
Gamma Island is an island, 1.6 km long, which marks the southwestern extremity of the Melchior Islands in the Palmer Archipelago. This island was first roughly charted and named "Ile Gouts" by the French Antarctic Expedition, 1903–05, under Jean-Baptiste Charcot, but that name has not survived in usage. The current name, derived from gamma, the third letter of the Greek alphabet, was probably given by Discovery Investigations personnel who roughly surveyed the island in 1927. The island was also surveyed by Argentine expeditions in 1942, 1943 and 1948. The Argentines call it Isla Observatorio and erected the Melchior Base there in 1947.

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.
