History

Although Severnaya Zemlya lies not far off the northern coast of Siberia, cartographers did not formally record it until the 20th century. Earlier explorers deemed that there was a land mass in the general area - note for example the report by Matvei Gedenschtrom and Yakov Sannikov made in 1810 at the time of their exploration of the New Siberian Islands. Later in the 19th century, Adolf Erik Nordenskiöld during the ''Vega'' expedition sailed very close to this land in 1878 but did not notice it. In 1882, the Danish Arctic explorer and naval officer Andreas Peter Hovgaard, leader of the Arctic survey ''Dijmphna'' expedition, set himself the goal of discovering land north of Cape Chelyuskin and exploring the unknown northeastern limits of the

. However, Hovgaard was prevented from accomplishing his objectives after having become trapped in thick ice, and his expedition was unable to reach even the shores of the Taymyr Peninsula. Even at the end of the 19th century, both Nansen's ''Fram'' expedition of 1895 and Eduard Toll's Russian polar expedition of 1900–02 on the ship ''Zarya'' failed to note any traces of land to the north of the strait between the Kara Sea and the Laptev Sea that they navigated.

The archipelago first appeared on the map with the 1913–1915 Arctic Ocean Hydrographic Expedition of the icebreakers ''Taimyr'' and ''Vaigach''. The chief organiser and first captain of the ''Vaygach'' was officer Aleksandr Vasiliyevich Kolchak of the Imperial Russian Navy. The expedition, privately financed, was launched in 1910 and led by Boris Vilkitsky on behalf of the Russian Hydrographic Service.

used by Russia at the time), members of Vilkitsky's expedition landed on what is now known as Cape Berg on present-day October Revolution Island. They raised the Russian flag on the shore and named the new territory Tayvay Land (, ''Zemlya Tayvay''), after the first syllable of each of their icebreakers' names. During the days that followed, Vilkitsky's expedition charted parts of the Laptev Sea coast of what they believed to be a single island. Barely six months later, in early 1914, by order of the Secretary of the Imperial Navy, the new discovery was renamed ''Emperor Nicholas II Land'' (, ''Zemlya Imperatora Nikolaya II''), after the ruling Emperor Nicholas II of Russia.

Later exploration and present era

In 1926, the Presidium of the Central Executive Committee of the USSR renamed the still not fully-explored land ''Severnaya Zemlya''. In May 1928, Umberto Nobile and his crew in the Airship ''Italia'' attempted to overfly the islands, but adverse weather conditions forced them to turn southward when only an hour or two from viewing the archipelago's coastline. In the spring of 1931, Georgy Ushakov, accompanied by the geologist Nikolay Urvantsev, the veteran surveyor Sergei Zhuravlev, and the radio-operator Vasily Khodov, thoroughly surveyed Severnaya Zemlya during a two-year expedition to the archipelago. Ushakov and his team established a small base at Golomyanny – the western end of Sredniy Island, off October Revolution Island's western coast. From there they made multiple surveying-trips into the interior and to the coastlines of the larger islands. The first detailed map drawn by the expedition's cartographers showed Severnaya Zemlya divided into four main islands. Geographic features of the territory were named after

Glaciers

Glaciers in the archipelago have a characteristic dome shape with a continuously decreasing surface towards their edges. Ice cliffs are found only at the base. The places where the glaciers reach the sea contribute to the formation of icebergs. The most active glacier fronts are the eastern side of the Academy of Sciences Glacier at Krenkel Bay as well as its southern side. Another quite active glacier is the Rusanov Glacier on the island of October Revolution with its terminus at Matusevich Fjord. October Revolution, with seven

The Podemnaya River and the Bolshaya River drain to the northwest between the Vavilov and Albanov glaciers, and the Bedovaya and Obryvistaya Rivers drain to the north between Albanov and Rusanov. The largest lake of the island and the entire archipelago, Fiordovoye, is located on the southwestern edge of the Karpinsky glacier. To the east and south of the island are the large Matusevich Fjord and the smaller Marat Fjord. They, together with the lake, encircle the Karpinsky ice cap. Cape October is located in the northern part of the island facing the Red Army Strait. ''Ostrov Vysokiy'' is an islet located in a small bay on October Revolution Island's southwest shores.

Komsomolets

Komsomolets Island () is the northernmost island of the Severnaya Zemlya group in the Russian

, and the third largest island in the group. It is the 82nd largest island on earth. The northernmost point of the island is called the Arctic Cape. This is the launching point for many Arctic expeditions. The area of this island has been estimated at . It rises to a height of . Some 65% of the island is covered with glaciers.

Pioneer Island

Pioneer Island, Ostrov Pioner in Russian. It is the westernmost of the large islands of the Severnaya Zemlya group and is separated from Komsomolets Island by the Yuny Strait. Pioneer island measures in area. This island houses the Pioneer Glacier. Thelodonti fossils from the Upper Silurian have been found in the island. Off Pioneer Island's southwestern end lies Krupskoy Island. This is a fairly large island, over in length and about in width. The sound that separates it from Pioneer is only in width. This island should not be confused with Pioneer Island in Canada ().

Schmidt Island

Schmidt Island, measuring , is located at the far northwestern end of the archipelago. This island is quite detached from the whole Severnaya Zemlya group. It is also its northernmost island and before modern climate warming it was fully in the region of permanent sea ice. This island is almost entirely covered by the Schmidt Ice Cap. Owing to its exposed position, the climate in the Schmidt Island's area is much colder than in the rest of the archipelago. Schmidt Island was named after the Soviet scientist Otto Schmidt.

Minor islands and island groups

Close to the main archipelago of Severnaya Zemlya there are a number of smaller islands and archipelagos. There are also many small coastal islands and islets in different locations, such as Krupskoy to the west of Pioneer and Naydenysh () near Cape Anuchin in October Revolution Island. Among the other minor islands the following deserve mention:

Sedov Archipelago

The Sedov Archipelago, formerly known as Sergey Kamenev Islands, is located just west of October Revolution Island on the Kara Sea side. The main islands of this archipelago are ''Sredny'' (the longest island), ''Domashnyy'', ''Strela'', and ''Figurnyy''. Close to the shore of October Revolution Island lies ''Obmannyy Island'' and further offshore southwards lies ''Dlinnyy Island''. These other coastal islands are sometimes included as part of the Sedov Group. ''Golomyanniy Meteorological Station'', located on the western tip of Sredniy Island at , was the wintering site and base of the 1931–32 expedition and has been taking continuous measurements since 1954. An official request has been forwarded to rename Domashnyy Island as ''Svyatoy Anastasii'' (), St. Anastasia Island.

Krasnoflotskiye Islands

Located just south of October Revolution Island in the Kara Sea. The Krasnoflotskiye Islands () extend from north to south in an almost straight line . The main islands are ''Sverdlova'' – very close to Cape Sverdlov on the coast, ''Bolshoy'' – not much larger than the others despite its name, ''Sredniy'' and ''Greben'' far offshore. All islands are devoid of vegetation. Two small islets named ''Opasnye'', which are also part of this group, lie to the southwest of Greben Island. The Krasnoflotskiye Islands were first sighted and mapped in August 1932 by the expedition of the All-Union Arctic Institute on the icebreaker ''Rusanov''. There is an Arctic Station in the Krasnoflotskiye Islands (AS-042), which has been operating since 1953.

Maly Taymyr and Starokadomsky

This is a small group including two main islands located in the Laptev Sea, off the far southeastern end of Bolshevik Island. Maly Taymyr, the largest island, has a land surface of and is at . Maly Taymyr was discovered by Boris Vilkitsky during the Arctic Ocean Hydrographic Expedition in 1913 and was named "Tsarevich Alexei Island" (), after the son of Zar Nicholas II of Russia. Following the 1917

the island was renamed "Maly Taymyr". In 2005 an official request was forwarded to the local government in Krasnoyarsk Krai in order to reinstate its former name to the island as ''Alexei Island''. '' Starokadomsky Island'' is close by to Maly Taymyr, located off its northwestern side and separated from it by a narrow sound. This island was named after Dr. Leonid Starokadomsky, one of the leaders of the 1913 Arctic Ocean Hydrographic Expedition.

Lishniy Island

Lishniy Island () is a coastal island located on the eastern side of the mouth of Akhmatov Fjord, southeast of Cape Unslicht, off Bolshevik Island's northern end at . The island has an irregular shape and is long with a maximum width of . A deep round lake with a diameter of is located in the western part of the island and is connected to the sea by a small channel. Almost all the island is rocky, except for the northwestern part. The highest point of Lishniy Island is South of Lishniy lies ''Yuzhnyy'', a smaller island, and two islets. Lishniy off Severnaya Zemlya should not be confused with Lishny Island off Toll Bay, south of the Firnley Islands.
