Peter I Island is an uninhabited volcanic island located in the Bellingshausen Sea, part of the Southern Ocean off the coast of Antarctica. It is the northernmost island of the South Shetland Islands archipelago and the only island in the group that is not claimed by any nation. The island is roughly circular, measuring 8 km in diameter, and is composed of an extinct volcano that rises to an elevation of 1,640 m above sea level.
The island was discovered in 1821 by Fabian Gottlieb von Bellingshausen, a Russian explorer, and named after Tsar Peter I of Russia. The island was claimed by Norway in 1929, but the claim was disputed by the Soviet Union. In 1939, the Soviet Union annexed the island and established a research station, which was abandoned in 1959.
In 1994, the island was declared a nature reserve by the Norwegian Polar Institute, and in 2002 it was designated a protected area under the Antarctic Treaty System. The island is home to a variety of wildlife, including seabirds, seals, and penguins.
The island is a popular destination for scientific research and has been visited by numerous scientific expeditions over the years. In 2018, a team of researchers from the Norwegian Polar Institute made the first-ever landing on Peter I Island, where they collected soil and rock samples for further study.
In addition to its scientific importance, the island is also of historical significance. During World War II, it was the site of a secret Soviet-German meeting in 1941, which resulted in the signing of the Lend-Lease Agreement. This agreement enabled the Soviet Union to receive military supplies from the United States in exchange for raw materials.
