Lambda Island (Primero de Mayo, isla)
Lambda Island is an island lying immediately north-west of Delta Island in the Melchior Islands, of the Palmer Archipelago in Antarctica. The island, the largest in the north-western part of the island group, was first roughly charted and named "Île Sourrieu" by the French Antarctic Expedition, 1903–05 under Jean-Baptiste Charcot, but that name has not survived in usage. The current name, derived from lambda, the 11th letter of the Greek alphabet, was given by Discovery Investigations personnel who roughly charted the island in 1927. The island was surveyed by Argentine expeditions in 1942, 1943 and 1948.
A lighthouse named ‘Primero de Mayo’ was erected on the island by Argentina in 1942. It was the first Argentine lighthouse in the Antarctic and has been designated a Historic Site or Monument (HSM 29), following a proposal by Argentina to the Antarctic Treaty Consultative Meeting.

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.
