Lambda Island is a small piece of land surrounded by water, located near Delta Island in the Melchior Islands. These islands are part of the Palmer Archipelago, which is in Antarctica. Lambda Island is the biggest island in the northwest part of this group.
The island was first mapped by the French Antarctic Expedition, 1903–05. This expedition was led by Jean-Baptiste Charcot. They named it "Île Sourrieu," but this name is no longer used. The name "Lambda Island" comes from lambda, which is the 11th letter of the Greek alphabet. People from a group called Discovery Investigations gave it this name in 1927. Later, Argentine teams surveyed the island in 1942, 1943, and 1948.
A Special Lighthouse in Antarctica
A lighthouse called ‘Primero de Mayo’ was built on Lambda Island in 1942. Argentina built this lighthouse. It was the very first Argentine lighthouse ever built in Antarctica.
This lighthouse is very important. It has been named a Historic Site or Monument (HSM 29). This happened after Argentina suggested it to the Antarctic Treaty Consultative Meeting. This means it is protected and recognized for its historical value.
