Bear Island (, ) is the southernmost island of the Norwegian Svalbard archipelago. The island is located at the limits of the Norwegian and Barents seas, approximately halfway between Spitsbergen and the North Cape. Bear Island was discovered by Dutch explorers Willem Barentsz and Jacob van Heemskerck on 10 June 1596. It was named after a polar bear that was seen swimming nearby. The island was considered terra nullius until the Spitsbergen Treaty of 1920 placed it under Norwegian sovereignty.

Despite its remote location and barren nature, the island has seen commercial activities in past centuries, such as coal mining, fishing and whaling. However, no settlements have lasted more than a few years, and Bear Island is now uninhabited except for personnel working at the island's meteorological station Bjørnøya radio. Along with the adjacent waters, it was declared a nature reserve in 2002.

History

Seafarers of the Viking era may have known Bear Island, but the documented history begins in 1596, when Willem Barentsz sighted the island on his third expedition. He named this island "Vogel Eylandt", "Bird Island" in English. Steven Bennet conducted further exploration in 1603 and 1604 and noted the then rich population of walrus. Starting in the early 17th century, the island was used mainly as a base for the hunting of walrus and other species of seals. Also, the eggs of seabirds were harvested from the large bird colonies until 1971.

The Muscovy Company claimed Bear Island for the English Crown in 1609, but it abandoned the site when walrus-hunting declined. A Russian settlement existed in the 18th century and its remains were later used as a basis for territorial claims by Imperial Russia in 1899 and again by the Soviet Union in 1947.

Bear Island has never been extensively settled. The remnants of a whaling station from the early 20th century can be seen at Kvalrossbukta ("walrus bay") in the southeast. From 1916 through 1925, coal was mined at a small settlement named Tunheim on the northeastern coast, but then the mining was given up as unprofitable. Due to the cold climate, the remains of the settlement, including a half-destroyed jetty and a steam locomotive, are relatively well-preserved.

The strategic value of Bear Island was recognised in the late 19th century, when Imperial Russia and Imperial Germany demonstrated their interests in the Barents Sea. The German journalist and adventurer Theodor Lerner visited the island in 1898 and 1899 and claimed rights of ownership. In 1899, the German fishery association Deutscher Seefischerei-Verein (DSV) started investigations of whaling and fishery in the Barents Sea. The DSV was secretly in contact with the German naval command and considered the possibility of an occupation of Bear Island. In reaction to these advances, the Russian Navy sent out the protected cruiser to investigate, and the Russians hoisted their flag over Bear Island on 21 July 1899. Although Lerner protested the action, no violence occurred and the matter was settled diplomatically with no definitive claims of sovereignty over Bear Island by any nation.

The whole island was privately owned by the coal mining company of Bjørnøen AS from 1918 to 1932, when the Norwegian state took over the shares. Bjørnøen AS now exists as a state-owned company, and it is jointly managed with Kings Bay AS, the company that runs the operations of Ny-Ålesund on Spitsbergen. A Norwegian radio station (Bjørnøya Radio, callsign: LJB ) was established in Herwighamna on the northern coast in 1919. It was later extended to include a meteorological station.

In 1932 and 1933, the island was a site of the first Polish polar expedition, related to the second International Polar Year. Three researchers—Czesław Centkiewicz (who later recounted the expedition in his book Wyspa Mgieł i Wichrów), Władysław Łysakowski and stayed there for an entire winter conducting meteorological and geophysical observations.

Since the shipping routes from the Atlantic Ocean to the ports of the arctic White Sea pass through the Barents Sea, the waters near Bear Island were of some strategic importance during World War II as well as during the Cold War. Although Svalbard was not occupied by Germany, the Kriegsmarine built several weather stations there as part of Operation Haudegen. An automated radio station was deployed on Bjørnøya in 1941. German forces attacked several arctic convoys with military supplies bound for the Soviet Union in the waters surrounding Bear Island. They inflicted heavy losses upon Convoy PQ 17 of June/July 1942, but they were ineffective in the Battle of the Barents Sea on New Year's Eve 1942. The waters southeast of Bear Island were the scene of more naval battles in 1943.

In November 1944, the Soviet Union proposed to annul the Spitsbergen Treaty with the intention of gaining sovereignty over Bear Island. Negotiations with Trygve Lie of the Norwegian government-in-exile did not lead to an agreement by the end of World War II, and the Soviet proposals were never carried out. The Soviet Union (and later, Russia) maintained some presence on Spitsbergen, however.

In 2002 a nature reserve was established that covers all of the island, except around the meteorological station. The reserve also includes the adjacent waters of a radius from the coast. In 2008, the decision was made to extend the reserve to a radius of from the coast covering on land and of sea area. Today, the island's only inhabitants are the nine staff members of the Norwegian meteorological station and radio station at Herwighamna. This station carries out meteorological observations and provides logistic and telecommunication services, including a radio watch on the HF channels 2182/2168 and the VHF channels 16/12. Weather forecasts are transmitted from the station twice daily, announced on HF 2182/VHF 16 at 10:05 am/pm UTC.

The Norwegian Polar Institute conducts annual expeditions to Bear Island, mostly concerned with ornithological research. Several other research projects, mostly pertaining to geography and climatology, are carried out less regularly. There are very few opportunities for individual travel to Bjørnøya.

Amateur radio operators occasionally conduct DXpeditions on the island during the summer months.

The first recorded case of the COVID-19 pandemic in Svalbard occurred on Bear Island on 6 October 2021. A Russian fisherman had been confirmed to have contracted the disease and was transported via helicopter to Longyearbyen to be treated at its hospital, where he made a full recovery. There have been 0 confirmed deaths from COVID-19 in Svalbard as of 2023.

Geography

Bear Island lies about south of mainland Spitsbergen and north-northwest of Ingøy in mainland Norway. It is located at the limits of the Norwegian and Barents Seas on Spitsbergen Bank, which extends southward from Spitsbergen and Edgeøya, forming a part of the continental shelf.

The island's outline is an approximate triangle pointing south with a greatest north–south extension of and a greatest east-west extension of . Its surface area is . The southern part of Bjørnøya is mountainous, the highest top being Miseryfjellet on the southeast coast at about above sea level.

Other notable mountains are Antarcticfjellet in the southeast, and Fuglefjellet, Hambergfjellet and Alfredfjellet in the southwest. The northern part of the island forms a rocky, lowland plain that covers some two thirds of the surface area.

Apart from a few sandy beaches, the coast is mostly steep, with high cliffs and notable signs of erosion such as caverns and isolated rock pillars. A number of anchorages and landing points exist, as well as a small harbor at Herwighamna on the north coast.

Hydrography Norwegian government agencies have conducted hydrographic surveys of Svalbard waters throughout the 20th century. The responsibility fell to the in 1928, its successor, the Norwegian Polar Institute from 1948, and the Norwegian Hydrographic Service from 1984. Land surveying and mapping are the responsibilities of the Polar Institute.

Water depths near the island and to the north and east do not much exceed , but become much greater to the south, and especially some to the west, where the continental shelf slopes into the deep water of the Norwegian Sea and Greenland Sea.

The lowland is strewn with shallow freshwater lakes that cover about in all. Several streams flow into the ocean, often via waterfalls along the steeper parts of the coast.

Climate

Bear Island, located well south of the main islands in the Svalbard Archipelago, has the mildest climate in Svalbard. A branch of the North Atlantic current carries warm water to the west of Svalbard, passing Bear Island on its way. This influences climate, making it much warmer than other polar regions at similar latitude. Bear Island's climate is maritime and polar (Köppen ET) with relatively high temperatures during the winter, and a large amount of precipitation. The large winter precipitation is very unusual in a high polar region, a result of Atlantic Lows sometimes going this far northeast due to open sea southwest of Bear Island. The record high was recorded June 1953. The record low is from March 1927. The annual mean temperature was in the period 1991–2020, thus threatening to melt permafrost on the island; by comparison, the annual mean temperature was in the period 1961–1990.

While winters are very long, the maritime moderation and the delay of salt water ice formation makes Bear Island have far fewer cold winters than a lot of mid-latitude climates on the larger continental landmasses. In summer, the maritime influence causes seasonal lag. This means that August is slightly milder than July, which is extremely uncommon at high latitudes. The seasonal lag is extreme in the winter with the coldest month being March, and April being colder than November.

The weather can be quite stable during summer months, although foggy conditions are common, occurring during 20% of all days in July. Fog develops when the warm air of the Atlantic Ocean, from farther south, passes over cold water. The average monthly precipitation is lowest in May, and highest in September and October.

Because Bear Island lies at a boundary between cold water of polar origin and warmer Atlantic water, water temperatures within a few dozen nautical miles of the island are quite variable, sometimes reaching in summer. During the winter fast ice develops on the coast, but it is rare on the open sea around Bear Island. The Barents Sea carries pack ice to Bjørnøya every winter, but a significant amount of ice is not common before February.

The polar night lasts from about November 8 through February 3, and the period of midnight sun from about May 2 through August 11. With just 595 hours of bright sunshine per year, Bear Island has the lowest average yearly sunshine in Europe.

Flora and fauna

Victor Summerhayes and Charles Elton visited Bear Island during the 1921 Oxford University Spitsbergen expedition and the location formed the basis of their pioneering ecological study which produced one of the first food web diagrams. There is a little plant growth, consisting mostly of moss and some scurvy grass, but no trees.
