Geography of Svalbard

Svalbard is an icy desert that is frigid and dry. The primary cause of its cold temperatures is because of its northern location, which affects how much solar energy it receives. Due to the curvature of the Earth, solar energy must heat a bigger area at the poles than it would at the equator. The sun is at a lower angle in the northern latitudes. This lack of radiation keeps the temperatures low, enables the formation of glaciers and permanent snow, and doubles the extent of sea ice from summer to winter.

Physical Features

Svalbard is an archipelago in the Arctic Ocean that belongs to Norway and is situated far north of the Arctic Circle. The islands are located around 580 miles (930 km) north of Troms, Norway, between the longitudes of 10° and 35° E and the latitudes of 74° and 81° N. Spitsbergen (formerly West Spitsbergen), North East Land, Edge Island, Barents Island, Prins Karls Foreland, Kvit Island (Gilles Land), Kong Karls Land (Wiche Islands), Bjrn (Bear) Island, and Hopen are the nine major islands that make up the archipelago. Svalbard has a total size of 24,209 square miles (62,700 square kilometres).

The largest island, Spitsbergen, measures 15,075 square miles (39,044 square kilometres). It is made up of nine main islands, with glaciers and snowfields covering 60% of the total surface. Newtontoppen and Perriertoppen are two mountain summits on the islands that reach heights of 1717 meters. Fjords, some of which are longer than 100 km, are profoundly carved into the north and west coasts. All major geological periods are represented in Svalbard, and fossils are simple to locate.

The greatest glaciers are in the north-east and encompass over 60% of the country. The majority of glaciers eventually reach the sea, where they create towering ice cliffs that can reach 50 meters in height. These ice fronts are calving in the summer, resulting in icebergs of varied sizes. Svalbard also features unusual polygonal stone patterns made by the frost, as well as unusually flat, ice-free valleys that are covered in lichen, flowers, and other vegetation.

Climate

Svalbard's particular physical landscape and natural processes are a result of its cold climate. The dominant landscape elements are rock, ice, and sea. There is no tall vegetation, and only lichen grows above 1100 meters. Svalbard has minor valley glaciers as well as enormous outlet glaciers that drain ice-caps, and 60% of the land is covered in ice. The landscape is eroded by glaciers and the rivers that flow from them, which subsequently carry and deposit the eroded sediments.

The mechanical processes of frost shatter, freeze-thaw, abrasion, and plucking are the key factors in weathering and erosion. Fjords, glacial valleys, arêtes, and nunataks (formed by erosion), outwash plains, alluvial fans, moraines, and braided streams (formed by deposition), are examples of glacial landforms. Additionally, Svalbard includes periglacial characteristics typical of cold climates, such as pingos, which are tiny hills.

Nearly everywhere above 100 meters of elevation, the ground is constantly frozen and impenetrable. Permafrost is what it is, and its thickness ranges from 10 to 45 meters. In the summer, only the very top layer thaws, allowing some plant development. It makes building and heating structures difficult, which is why certain structures and pipes are on short stilts.

The island group's extensive glaciation and northern latitude have left no area suitable for agriculture. Although the archipelago lacks any native trees, it does include bushes like crowberry and cloudberry. The majority of the year, Spitsbergen's west coast can be sailed thanks to favourable winds that prevent ice build-up. Arctic weather prevails in the Svalbard archipelago, but the warm North Atlantic Current that runs along its western and northern coasts moderates it.

This means that the untamed, rocky mountainous islands will experience cool summers and cold winters. The west coast is often free of ice for roughly half the year, while the high land in the interiors of the islands is typically covered in ice all year long. Along the west and north coasts, there are a lot of fjords.

Resources

There are numerous mineral resources in Svalbard, and Spitsbergen's west side has seen substantial coal mining. The entrance to Bellsund, a transit location for coal exports, is frequently blocked by ice floes, and periodically portions of the north-eastern coast are impassable to maritime traffic.

Flora

The populations of whales, seals, and walruses are still far lower than they were even 200 years ago (the typical age of a Greenland whale). Locally, polar bear populations are rebounding after the significant culls that occurred in the 1960s and 1970s as a result of the accessibility of snow scooters, but the polar bear remains endangered globally as a result of unsustainable levels of human slaughter and marine water pollution.

Several bird populations in Svalbard are being watched after, including those of the puffin, Arctic skua, kittiwake, and fulmar. The Norwegian government's North East Svalbard Nature Reserve is a prime example of category 1b (Wilderness Area). In the northeast of the Svalbard archipelago, the reserve encompasses the islands of Spitzbergen, Nordaustlaudet, Edgey, Barentsy, and Prins Karls Forland as well as the adjacent territorial seas, covering a total of 1.9 million hectares.

Svalbard Global Seed Vault

The largest island in the Norwegian archipelago of Svalbard, Spitsbergen, is home to the Svalbard Global Seed Vault, a secure facility designed to protect the seeds of the world's food crops in the case of a global emergency. The location was chosen because of the permafrost and extreme cold, which would assist protect the seeds in the event that the cooling systems in the vault failed. Construction started in June 2006, and on February 26, 2008, the vault's first shipment of seeds was ceremonially delivered.

The Global Seed Vault, developed by Norway in collaboration with the Global Crop Diversity Trust, has received support from more than 100 nations. It was intended as a comprehensive storage facility that could safeguard genetic resources that could be used to breed new varieties that are adapted to a changing climate or a novel plant disease and protect the genetic diversity of humanity's food crops from the threat of a global catastrophe, such as nuclear war.

Conclusion

The Arctic Ocean archipelago of Svalbard is a frigid desert with rocky terrain, glaciers, and unusual geological formations. Its arctic latitude, harsh temperature, and widespread ice have shaped its physical features and put a cap on agricultural activity. In addition to being a haven for a variety of wildlife, including polar bears, whales, seals, and many bird species, the area is rich in mineral resources, particularly coal.

The North Atlantic Current, which affects Svalbard's climate, causes chilly summers and cold winters, with ice covering much of the country all year long. The archipelago is distinguished by its breath-taking fjords, significant ice formations, and a lush natural setting.
