The Preobrashenije Island ( Russian остров Преображения , "Island of the Transfiguration") is a Russian island in the Chatanga Gulf of the Laptev Sea . Politically it belongs to the Anabarski ulus of the Sakha Republic .
geography
The island is located about 13 kilometers north of Bolshoi Begichev and 27 kilometers east of Cape Sibirsky on the Taimyr Peninsula . It has the shape of a sickle about eight kilometers long and is up to 1.8 kilometers wide. Their maximum height is 77 meters. The coast to the east and northeast has steep cliffs , to the west the terrain slopes more gently to a pebbly beach that lines Neupokoyeva Bay. A spit has formed, especially on the southern tip of the island . There are no running waters on the island, but there is a small freshwater lake in the south.
Flora and fauna
The island is covered by treeless tundra . In addition to mosses , lichens and grasses, there are dwarf shrubs .
The chain of polynyas that stretches off the coast of the Laptev Sea provides animals with a good food base even in winter. Walruses can be found on the shallow beach of Preobraschenije Island . On the cliffs in the northwest of the island there are colonies of seabirds with around 10,000 breeding pairs. BirdLife International therefore designates the island as an Important Bird Area (Ru3085). Even polar bears visit the island.
history
The Preobraschenije island was in 1736 by the headed by Lieutenant Vasily Prontschischtschew standing Lena - Chatanga group of the northern section of the Great Northern Expedition discovered 1733-1743. The head of the northern group, Lieutenant Chariton Laptev , named them after the church holiday in 1739 . When Adolf Erik Nordenskiöld first completely crossed the Northeast Passage with the Vega in 1878 , the island was explored by the expedition participants and an inventory of the flora was made. After that, it was probably not re-entered until 1908, when the Russian polar explorer Nikifor Begitschew (1874–1927) visited it for commercial reasons. After the North Sea Route Headquarters was established in 1932, Preobrashenije Island became an important landmark for all ships sailing the Northeast Passage. The hydrographic expedition led by Sergei Lappo (1895–1972) measured and mapped the island in 1933 and temporarily named it "Wstretschny". In 1937/38 a Soviet ship convoy led by the icebreaker Lenin was trapped by the ice in Chatanga Gulf. The zoologist GL Rutilewski visited the Preobraschenije Island with a dog sled . The polar station set up on the island after the Second World War was closed again in 1991 for cost reasons.
