Nordenskiöld Archipelago

The Nordenskiöld Archipelago or Nordenskjold Archipelago (Template:Langx) is a large and complex cluster of about 90 islands in the eastern region of the Kara Sea. Its eastern limit lies west of the Taymyr Peninsula. The archipelago is part of the Taymyrsky Dolgano-Nenetsky District of the Krasnoyarsk Krai administrative division of Russia.

These are mainly formed by igneous rocks and are covered with tundra vegetation. Except for two polar stations, one which was permanent in Russky Island between 1935 and 1999 and a temporary one in Tyrtov Island (Tyrtova) (1940–1975), there is no permanent human presence in any island of the archipelago.

Geography and environment

The Nordenskiöld Archipelago stretches for almost from west to east and about from north to south in the Kara Sea, off the Siberian shores, where there are large coastal islands around Taymyr Island. The average elevation of the islands is relatively low. The highest point of the archipelago (107 m) is located in Chabak, one of the islands of the Vilkitsky subgroup. Some of the islands have wetlands.

The climate in the Nordenskiöld Archipelago is Arctic and severe. The sea surrounding the multitude of island groups is covered with fast ice in the winter and it is obstructed by pack ice even in the summer, which lasts only about two months in a normal year.

Birds

The islands regularly support significant populations of brent geese and ivory gulls. The archipelago has been recognised as an Important Bird Area (IBA) by BirdLife International.

History

This archipelago was first reported in 1740 by Nikifor Chekin, who accompanied Semion Chelyuskin in the Great Northern Expedition. Many years later it was named after arctic explorer Adolf Erik Nordenskiöld by Norwegian polar explorer Fridtjof Nansen in his maps of the northern coasts and seas of Siberia.

In 1893, when Fridtjof Nansen's Fram was near the Nordenskjold Archipelago, it got stuck in dead water. This is a strange phenomenon that typically occurs in fjords, as glaciers melt and a form a shallow layer of freshwater ice over salty water. This is how Nansen described the phenomenon:

Towards the end of August 1893, when the Fram was off the Taymyr Peninsula, near the Nordenskiöld Archipelago, "dead water" was encountered. This is a peculiar phenomenon, which occurs where a surface layer of fresh water rests upon the salt water of the sea. It manifests itself in the form of larger or smaller ripples or waves stretching across the wake, the one behind the other, arising sometimes as far forward as almost midships. When caught in dead water, Fram appeared to be held back, as if by some mysterious force, and she did not always answer the helm. In calm weather, with a light cargo, Fram was capable of 6 to 7 knots. When in dead water she was unable to make 1.5 knots. We made loops in our course turned sometimes right around, tried all sorts of antics to get clear of it, but to very little purpose.

In 1900 the islands of the Nordenskiöld Archipelago were explored and mapped with accuracy by Captain Fyodor Andreyevich Matisen during the Russian polar expedition of 1900–1902. This venture was led by Baron Eduard Von Toll on behalf of the Imperial Russian Academy of Sciences aboard ship Zarya. Toll sent Matisen to make a survey of the archipelago in the early spring while the Zarya was wintering close to Taymyr Island. Most islands of the Nordenskiöld Archipelago were charted and named during this effort. Matisen crisscrossed the whole vast frozen area on dogsled twice. He divided the archipelago into four of the five main groups mentioned above and named more than forty islands.

Like Nansen, Eduard Toll observed that it was difficult to navigate through the archipelago on account of the ice.

After the Russian Revolution, the archipelago was explored in the 1930s by a Soviet expedition on the icebreaker Sedov.

In 1937 the Arctic Institute of the USSR organized an expedition on ship Toros. The purpose of this expedition was to explore the Nordenskiöld Archipelago and to thoroughly investigate the Northern Sea Route in the Kara Sea. The Toros overwintered in Ledyanaya Bay on Bonevi Island west of Taymyr Island and sailed back to Archangelsk during the summer thaw after having explored many Kara Sea islands.

On 25 August 1942, during Operation Wunderland, Kriegsmarine cruiser Admiral Scheer fell upon the Russian icebreaker Sibiryakov (under the command of Captain Kacharev) off the northwest coast of Russky Island at the northern end of the Nordenskiöld Archipelago. The Sibiryakov resisted but was sunk by the German warship. Then Admiral Scheer headed southwest in order to attack the Soviet military installations at Dikson.

Since May 1993 the Nordenskiöld Archipelago is part of the Great Arctic State Nature Reserve, the largest nature reserve of Russia. The Arctic station at Russky Island was closed in 1999.
