35-616: The main Voronina Island is about 9 km long and 6 km wide and is covered with tundra vegetation and ice. The northern islet is narrow, about 5 km in length and little more than 500 metres in width. These islands are located in the northeastern regions of the Kara Sea , about 130 km west of Severnaya Zemlya 's shores and 72 km NNE of Kirova Island of the Kirov group. The sea surrounding these lonely two islands

70-729: Is 21 km (13 mi) from east to west. The main island is called Bolshoy . The sea surrounding the Arkticheskiy Institut Islands is covered with packed ice in the long winter and the climate is severe. There are numerous ice floes even in the summer. This island group belongs to the Krasnoyarsk Krai administrative division of the Russian Federation and is part of the Great Arctic State Nature Reserve ,

105-478: Is a compact archipelago of narrow islands covered with tundra vegetation. The islands are located in the Kara Sea , about 173 km (107 mi) north of the coast of Siberia , and just 45 km (28 mi) south of the nearest island group, the Izvesti Tsik Islands . The distance between the northern and the southern end of the archipelago is 49.5 km (30.8 mi) and its maximum width

140-743: Is also a breeding ground for polar bears and a wildlife refuge part of the Great Arctic State Nature Reserve , the largest nature reserve of the Russian Arctic. The Voronina Islands have been named after Soviet Navy Captain Vladimir Voronin . Since "Voronina" is a Russian genitive, the combination "Voronina Islands" is technically incorrect. Even so, the name "Voronina Island" (or "Islands") has become popular and its use has been widespread in this manner for many decades and in many modern maps and atlases. "Voronin Islands", which would be

175-742: Is also affected by the water inflow from the Barents Sea , which brings 0.6 Sv in August and 2.6 Sv in December. The advected water originates from the Atlantic , but it was cooled and mixed with freshwater in the Barents Sea before it reaches the Kara Sea. Simulations with the Hamburg shelf ocean model (HAMSOM) suggest that no typical water current pattern consists in the Kara Sea throughout

210-414: Is covered with pack ice in the winter and there are numerous ice floes even in the summer, which lasts barely two months. The climate is so severe that there are years where at Voronina Island's latitude the surrounding waters of the Kara Sea don't melt and remain frozen solid through the summer. This island group belongs to the Krasnoyarsk Krai administrative division of the Russian Federation . Voronina

245-538: Is derived from a Nenets word meaning ' hummocked ice '. The International Hydrographic Organization defines the limits of the Kara Sea as follows: There are many islands and island groups in the Kara Sea. Unlike the other marginal seas of the Arctic, where most islands lie along the coasts, in the Kara Sea many islands, like the Arkticheskiy Institut Islands , the Izvesti Tsik Islands ,

280-487: Is roughly 1,450 km (900 mi) long and 970 km (600 mi) wide with an area of around 880,000 km (339,770 sq mi) and a mean depth of 110 metres (360 ft). Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. The Kara Sea contains the East-Prinovozemelsky field (an extension of

315-590: The Gercules . Georgy Sedov intended to reach Franz Josef Land on ship, leave a depot over there, and sledge to the pole. Due to the heavy ice the vessel could only reach Novaya Zemlya the first summer and wintered in Franz Josef Land . In February 1914 Sedov headed to the North Pole with two sailors and three sledges, but he fell ill and died on Rudolf Island . Georgy Brusilov attempted to navigate

350-617: The Icebreaker Sedov carried groups of scientists to Severnaya Zemlya , the last major piece of unsurveyed territory in the Soviet Arctic; the archipelago was completely mapped under Georgy Ushakov between 1930 and 1932. Particularly worth noting are three cruises of the Icebreaker Sadko , which went farther north than most; in 1935 and 1936 the last unexplored areas in the northern Kara Sea were examined and

385-876: The Izvestiy TSIK Islands , the Arctic Institute Islands , the Svordrup Island , Uedineniya (Ensomheden) and a number of smaller islands. This section represents rather fully the natural and biological diversity of Arctic sea islands of the eastern part of the Kara Sea. Nearby, the Franz Josef Land and Severny Island in northern Novaya Zemlya are also registered as a sanctuary, the Russian Arctic National Park . Arkticheskiy Institut Islands The Arkticheskiy Institut Islands or Arctic Institute Islands ( Russian : Острова Арктического института )

420-620: The Kirov Islands , Uedineniya or Lonely Island, Wiese Island , and Voronina Island are located in the open sea of its central regions. The largest group in the Kara Sea is by far the Nordenskiöld Archipelago , with five large subgroups and over ninety islands. Other important islands in the Kara Sea are Bely Island , Dikson Island , Taymyr Island , the Kamennyye Islands and Oleni Island . Despite

455-735: The Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia . The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island , Franz Josef Land , to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya . The Kara Sea

490-514: The Northeast Passage , was trapped in the Kara Sea, and drifted northward for more than two years reaching latitude 83° 17' N. Thirteen men, headed by Valerian Albanov , left the vessel and started across the ice to Franz Josef Land , but only Albanov and one sailor ( Alexander Konrad ) survived after a gruesome three-month ordeal. The survivors brought the ship log of St. Anna , the map of her drift, and daily meteorological records, but

525-578: The Soviet fleet under fair weather conditions. In October 2010, the Russian government awarded a license to Russian oil company Rosneft for developing the East-Prinovozemelsky oil and gas structure in the Kara Sea. There is concern about radioactive contamination from nuclear waste the former Soviet Union dumped in the sea and the effect this will have on the marine environment. According to an official "White Paper" report compiled and released by

560-627: The Vtoroy under Captain A. Skuratov. After entering the little-explored Kara Sea, they sailed to the mouth of the Ob River . Malygin took careful observations of these hitherto almost unknown areas of the Russian Arctic coastline. With this knowledge he was able to draw the first somewhat accurate map of the Arctic shores between the Pechora River and the Ob River . In 1878, Finnish explorer Adolf Erik Nordenskiöld on ship Vega sailed across

595-612: The West Siberian Oil Basin ), containing significant undeveloped petroleum and natural gas . In 2014, US government sanctions resulted in Exxon having until 26 September to discontinue its operations in the Kara Sea. It is named after the Kara river (flowing into Baydaratskaya Bay ), which is now relatively insignificant but which played an important role in the Russian conquest of northern Siberia. The Kara river name

630-476: The genitive case to illustrate the islands' relationship to the institute, while the English name uses the nominative case and the relationship is inferred using word order . Transliterations like "Ostrova Arkticheskovo Instituta" as well as translations like "Arctic Institute Islands" may be used as an alternative, especially by Russian speakers writing for an English speaking audience. Sidorova Island

665-802: The K-27 nuclear submarine with its two reactors loaded with nuclear fuel. The Great Arctic State Nature Reserve —the largest nature reserve of Russia—was founded on 11 May 1993, by Resolution No. 431 of the Government of the Russian Federation (RF). The Kara Sea Islands section (4,000 km ) of the Great Arctic Nature Reserve includes: the Sergei Kirov Archipelago , the Voronina Island ,

700-528: The Kara Sea from Gothenburg , along the coast of Siberia, and despite the ice packs, got to 180° longitude by early September. Frozen in for the winter in the Chukchi Sea , Nordenskiöld waited and bartered with the local Chukchi people . The following July, the Vega was freed from the ice, and continued to Yokohama , Japan. He became the first to force the Northeast Passage . The largest group of islands in

735-516: The Kara Sea, the Nordenskiöld Archipelago , has been named in his honour. The year 1912 was a tragic one for Russian explorers in the Kara Sea. In that fateful year unbroken consolidated ice blocked the way for the Northern Sea Route and three expeditions that had to cross the Kara Sea became trapped and failed: Sedov 's on vessel St. Foka , Brusilov 's on the St. Anna , and Rusanov 's on

770-624: The Novaya Zemlya Trough at depths of up to 380 meters. Liquid low-level wastes were released in the open Barents and Kara Seas. A subsequent appraisal by the International Atomic Energy Agency showed that releases are low and localized from the 16 naval reactors (reported by the IAEA as having come from seven submarines and the icebreaker Lenin ) which were dumped at five sites in the Kara Sea. Most of

805-533: The Russian government in March 1993, the Soviet Union dumped six nuclear submarine reactors and ten nuclear reactors into the Kara Sea between 1965 and 1988. Solid high- and low-level wastes unloaded from Northern Fleet nuclear submarines during reactor refuelings were dumped in the Kara Sea, mainly in the shallow fjords of Novaya Zemlya, where the depths of the dumping sites range from 12 to 135 meters, and in

840-523: The destiny of those who stayed on board remains unknown. In the same year the expedition of Vladimir Rusanov was lost in the Kara Sea. The prolonged absence of those three expeditions stirred public attention, and a few small rescue expeditions were launched, including Jan Nagórski 's five air flights over the sea and ice from the NW coast of Novaya Zemlya . After the Russian Revolution in 1917,

875-858: The dumped reactors had suffered an accident. The Soviet submarine K-27 was scuttled in Stepovogo Bay with its two reactors filled with spent nuclear fuel. At a seminar in February 2012 it was revealed that the reactors on board the submarine could re-achieve criticality and explode (a buildup of heat leading to a steam explosion vs. nuclear). The catalogue of waste dumped at sea by the Soviets, according to documents seen by Bellona, includes some 17,000 containers of radioactive waste , 19 ships containing radioactive waste, 14 nuclear reactors, including five that still contain spent nuclear fuel; 735 other pieces of radioactively contaminated heavy machinery, and

910-491: The entrance to the Kara Sea. Not until 1580 did another English expedition, under Arthur Pet and Charles Jackman , attempt its passage. They too failed to penetrate it, and England lost interest in searching for the Northeast Passage . In 1736–1737 Russian Admiral Stepan Malygin undertook a voyage from Dolgy Island in the Barents Sea . The two ships in this early expedition were the Perviy , under Malygin's command and

945-500: The grammatically correct way of naming these islands in English, is very rarely used. 78°14′N 93°41′E  /  78.233°N 93.683°E  / 78.233; 93.683 This Krasnoyarsk Krai location article is a stub . You can help Misplaced Pages by expanding it . Kara Sea The Kara Sea is a marginal sea , separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya , and from

980-443: The high latitude, all islands are unglaciated except for Ushakov Island at the extreme northern limit of the Kara Sea. Water circulation patterns in the Kara Sea are complex. The Kara Sea tends to be sea ice covered between September and May, and between May and August heavily influenced by freshwater run-off (roughly 1200 km yr ) from the Russian rivers (e.g., Ob , Yenisei , Pyasina , Pur , and Taz ). The Kara Sea

1015-547: The ice cover of Lake Qinghai on the Tibetan Plateau . The Kara Sea was formerly known as Oceanus Scythicus or Mare Glaciale and it appears with these names in 16th century maps. Since it is closed by ice most of the year it remained largely unexplored until the late nineteenth century. In 1556 Stephen Borough sailed in the Searchthrift to try to reach the Ob River , but he was stopped by ice and fog at

1050-589: The largest nature reserve of Russia. The Arkticheskiy Institut Islands were named in honor of the Arctic Institute of the USSR, which was then known as "All-Union Arctic Institute". The combination "Arkticheskiy Institut Islands" uses the Russian words for "arctic" and "institute" in a way which would be grammatically incorrect in Russian because of the Russian grammatical case system . The Russian name uses

1085-595: The models, while another study from that year suggests that the decline in BKS ice reduces snow cover in the North Eurasia but increases it in central Europe. There are also potential links to summer precipitation: a connection has been proposed between the reduced BKS ice extent in November–December and greater June rainfall over South China . One paper even identified a connection between Kara Sea ice extent and

1120-529: The scale and scope of exploration of the Kara Sea increased greatly as part of the work of developing the Northern Sea Route. Polar stations, of which five already existed in 1917, increased in number, providing meteorologic, ice reconnaissance, and radio facilities. By 1932 there were 24 stations, by 1948 about 80, and by the 1970s more than 100. The use of icebreakers and, later, aircraft as platforms for scientific work were developed. In 1929 and 1930

1155-491: The small and elusive Ushakov Island was discovered. In the summer of 1942, German Kriegsmarine warships and submarines entered the Kara Sea to destroy as many Russian vessels as possible. This naval campaign was named " Operation Wunderland ". Its success was limited by the presence of ice floes, as well as bad weather and fog. These effectively protected the Soviet ships, preventing the damage that could have been inflicted on

1190-579: The state of sea ice and weather conditions elsewhere than in any other area. The first study proposing a connection between floating ice decline in the Barents Sea and the neighbouring Kara Sea and more intense winters in Europe was published in 2010, and there has been extensive research into this subject since then. For instance, a 2019 paper holds BKS ice decline responsible for 44% of the 1995–2014 central Eurasian cooling trend, far more than indicated by

1225-477: The year. Depending on the freshwater run-off, the dominant wind patterns, and the sea ice formation, the water currents change. Barents Sea is the fastest-warming part of the Arctic, and some assessments now treat Barents sea ice as a separate tipping point from the rest of the Arctic sea ice, suggesting that it could permanently disappear once the global warming exceeds 1.5 degrees. This rapid warming also makes it easier to detect any potential connections between
