Lambda Island is anisland lying immediately north-west ofDelta Island in theMelchior Islands, of thePalmer Archipelago inAntarctica. The island, the largest in the north-western part of the island group, was first roughly charted and named "Île Sourrieu" by theFrench Antarctic Expedition, 1903–05 underJean-Baptiste Charcot, but that name has not survived in usage. The current name, derived fromlambda, the 11th letter of theGreek alphabet, was given byDiscovery Investigations personnel who roughly charted the island in 1927. The island was surveyed by Argentine expeditions in 1942, 1943 and 1948.[1]
Alighthouse 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 aHistoric Site or Monument (HSM 29), following a proposal by Argentina to theAntarctic Treaty Consultative Meeting.[2]
