Through Peninsula, Russia and Europe

While humans had already settled in the north of the peninsula in the 7th–5th millennium BC, the rest of its territory remained uninhabited until the 3rd millennium BC, when various peoples started to arrive from the south. By the 1st millennium CE only the Sámi people remained. This changed in the 12th century, when Russian Pomors discovered the peninsula's rich resources of game and fish. Soon after, the Pomors were followed by the tribute collectors from the Novgorod Republic, and the peninsula gradually became a part of the Novgorodian lands. However, the Novgorodians established no permanent settlements until the 15th century, and Russian migration continued in the following centuries.

The Soviet period (1917–1991) saw a rapid population increase, although most of the new arrivals remained confined to urbanized territories along the sea coast and the railroads. The Sámi people were subjected to forced collectivization, including forced relocation to Lovozero and other centralized settlements, and overall the peninsula became heavily industrialized and militarized, largely due to its strategic position (as the pre-eminent Soviet ice-free Atlantic coast) and to the discovery of the vast apatite deposits in the 1920s. As a result, the peninsula suffered major ecological damage. After the 1991 dissolution of the Soviet Union, the economy went into decline. Its population fell from 1,150,000 in 1989 to 795,000 in 2010. The peninsula recovered somewhat in the early 21st century, and is the most industrially developed and urbanized region in northern Russia.

Despite the peninsula's northerly location, its proximity to the North Atlantic Current (an extension of the Gulf Stream) leads to unusually high temperatures in winter, but also results in high winds due to the temperature variations between land and the Barents Sea. Summers are rather chilly, with the average July temperature of only 11 °C (52 °F). The peninsula is covered by taiga in the south and by tundra in the north, where permafrost limits the growth of trees, resulting in landscape dominated by shrubs and grasses. The peninsula supports a small variety of mammals, and its rivers are an important habitat for the Atlantic salmon. The Kandalaksha Nature Reserve, established to protect the population of common eider, is located in the Kandalaksha Gulf. The peninsula is also the site of the Kola Superdeep Borehole, the deepest hole drilled into the Earth.

Geography

Location and overview

The peninsula is located in the far northwest of Russia, almost completely inside the Arctic Circle, and is bordered by the Barents Sea in the north and the White Sea in the east and southeast. Geologically, the peninsula occupies the northeastern edge of the Baltic Shield. The western border of the peninsula stretches along the meridian from the Kola Bay through the valley of the Kola River, Lake Imandra, and the Niva River to the Kandalaksha Gulf, although some sources push it all the way west to Russia's border with Finland.

Under a more restrictive definition, the peninsula covers an area of about 100,000 square kilometers (39,000 sq mi). The northern coast is steep and high, while the southern coast is flat. The western part of the peninsula is covered by two mountain ranges: the Khibiny Mountains and the Lovozero Massif; the former contains the highest point of the peninsula—Yudychvumchorr. Mount Chasnachorr, the height of which is 1,191 meters (3,907 ft), had been formerly considered the highest point of the Khibiny. The Keyvy drainage divide lies in the central part. The mountainous reliefs of the Murman and Kandalaksha Coasts stretch from southeast to northwest, mirroring the peninsula's main orographic features.

Administratively, the territory of the peninsula consists of Lovozersky and Tersky Districts, parts of Kandalakshsky and Kolsky Districts, as well as the territories subordinated to the cities and towns of Murmansk, Ostrovnoy, Severomorsk, Kirovsk, and parts of the territories subordinated to Apatity, Olenegorsk, and Polyarnye Zori.

Natural resources

Because the last ice age removed the top sediment layer of the soil, the surface of Kola Peninsula is extremely rich in various ores and minerals, including apatites and nephelines; copper, nickel, and iron ores; mica; kyanites; ceramic materials, as well as rare-earth elements and non-ferrous ores. Deposits of construction materials such as granite, quartzite, and limestone are also abundant. Diatomaceous earth deposits are common near lakes and are used to produce insulation.

Climate

Proximity of the peninsula to the Gulf Stream leads to unusually high temperatures in winter for the region, resulting in significant temperature variations between land and the Barents Sea and in fluctuating temperatures during high winds. Cyclones are typical during the cold seasons, while the warm seasons are characterized by anticyclones. Monsoon winds are common in most areas, with south and southwesterly winds prevailing in winter months and with somewhat more pronounced easterly winds in summer. Strong storm winds blow for 80–120 days a year. The waters of the Murman Coast remain warm enough to remain ice-free even in winter.

Precipitation levels on the peninsula are rather high: 1,000 millimeters (39 in) in the mountains, 600–700 millimeters (24–28 in) on the Murman Coast, and 500–600 millimeters (20–24 in) in other areas. The wettest months are August through October, while March and April are the driest.

The average temperature in January is about −10 °C (14 °F), with lower temperatures typical in the central parts of the peninsula. The average temperature in July is about +11 °C (52 °F). Record lows reach −50 °C (−58 °F) in the central parts and −35 to −40 °C (−31 to −40 °F) on the coasts. Record highs exceed +30 °C (86 °F) almost on all the territory of the peninsula. First frosts occur as early as August and may last through May and even June.

Most areas of the Kola Peninsula are subarctic climate (Köppen climate classification: Dfc). The nearby islands usually belong to tundra (Köppen climate classification: ET).

Flora and fauna

The peninsula is covered by taiga in the south and tundra in the north. In the tundra, cold and windy conditions and permafrost limit the growth of the trees, resulting in a landscape dominated by grasses, wildflowers, and shrubs such as dwarf birch and cloudberry. In northern coastal areas, stony and shrub lichens are common. The taiga in the southern areas is composed mostly of pine trees and spruces.

Reindeer herds visit the grasslands in summer. Other animals include red and Arctic foxes, wolverines, moose, otters, and lynx in the southern areas. American minks, which were released near the Olenitsa River in 1935–1936, are now common throughout the peninsula and are commercially hunted. Beavers, which became endangered by 1880, were re-introduced in 1934–1957. All in all, thirty-two species of mammals and up to two hundred bird species inhabit the peninsula.

Beluga whales are the only cetacean being common around the peninsula. Other dolphins, including Atlantic white-sided dolphins, white-beaked dolphins, and harbor porpoises, as well as large whales, such as bowhead, humpback, blue, and finback, also visit the area.

The coasts of the Kandalaksha Gulf and the Barents Sea are important breeding grounds for bearded seals and ringed seals. The Barents Sea is one of the only places the rare Gray seals can be found. Greenland seals, or harp seals, also can be seen from time to time.

Twenty-nine species of fresh water fish are recognized on the territory of peninsula, including trout, stickleback, northern pike, and European perch. The rivers are an important habitat for the Atlantic salmon, which return from Greenland and the Faroe Islands to spawn in fresh water. As a result of this, a recreational fishery has been developed, with a number of remote lodges and camps available to host sport-fishermen. The Kandalaksha Nature Reserve, established in 1932 to protect the population of common eider, is organized in thirteen clusters located in the Kandalaksha Gulf of the Kola Peninsula and along the coasts of the Barents Sea.

Hydrology

The Kola Peninsula has many small but fast-moving rivers with rapids. The most important of them are the Ponoy, the Varzuga, the Umba, the Teriberka, the Voronya, and the Yokanga. Most rivers originate from lakes and swamps and collect their waters from melting snow. The rivers become icebound during the winter, although the areas with strong rapids freeze later or not at all.

Major lakes include Imandra, Umbozero, and Lovozero. There are no lakes with an area smaller than 0.01 square kilometers (0.0039 sq mi). Recreational fishery is developed in the region.

Ecology

The Kola Peninsula as a whole suffered major ecological damage, mostly as a result of pollution from the military (particularly naval) production, industrial mining of apatite, and military nuclear waste. About 137 active and 140 decommissioned or idle naval nuclear reactors, produced by the Soviet military, remain on the peninsula. For thirty years, nuclear waste had been dumped into the sea by the Northern Fleet and Murmansk Shipping Company. There is also evidence of contamination from the 1986 Chernobyl disaster, with contaminants being found in the flesh of reindeer and other animals, and from the 1972 and 1984 controlled nuclear explosions 21 kilometers (13 mi) northwest of Kirovsk. Additionally, several nuclear weapons test ranges and radioactive waste storage facilities exist on the peninsula.

The main industrial pollution source is Norilsk Nickel in Monchegorsk—the large smelters responsible for over 80% of the sulfur dioxide emissions and for nearly all nickel and copper emissions. Since 1998, SO2 emissions in the area have dropped by almost 60%, from 88.3 thousand tonnes to 37.3 thousand tonnes in 2016, according to Norilsk Nickel. Based on its new 'Sulphur programme 2.0', Norilsk Nickel has set itself staged targets in cutting down sulphur dioxide emissions, which can have negative health and environmental effects. The ultimate aim is a 95% reduction (compared to 2015) in SO2 by 2030 for its Polar Division on the Taimyr peninsula, which includes its Nadezhda smelter and Copper plant, partly through a SO2 capture solution. Other polluters of note include the thermal power stations in Apatity and Murmansk.
