Svalbard is an archipelago in the Arctic Ocean roughly centered on 78° north latitude and 20° east longitude. The archipelago is the northernmost part of the Kingdom of Norway. The three main islands in the group consist of Spitsbergen (the largest island), Nordaustlandet and Edgeøya. There are also a number of smaller islands, such as Barents Island (Barentsøya) (), Kvitøya (), Prins Karls Forland (English: Prince Charles Foreland) (), Kongsøya (), Bear Island (), Svenskøya (), Wilhelm Island () and other smaller islands or skerries (). Climate There is no arable land in the island group due to heavy glaciation and the northern latitude. There are no trees native to the archipelago, but there are shrubs such as crowberry and cloudberry. The west coast of Spitsbergen remains navigable most of the year, due to favorable winds which keep the area ice-free. Norway claims a fishery protection zone, but this is not recognized by neighboring Russia. The climate of the Svalbard archipelago is arctic, tempered by warm North Atlantic Current along the west and northern coasts. This means cool summers and cold winters along the wild, rugged mountainous islands. The high land of the island interiors is generally ice covered year round, with the west coast clear of ice about one half of the year. There are many fjords along west and north coasts Resources Svalbard has many mineral resources, and coal was mined extensively on the west side of Spitsbergen. Ice floes often block up the entrance to Bellsund (a transit point for coal exports) on the west coast and occasionally make parts of the northeastern coast inaccessible to maritime traffic Environmental issues Although many prior adverse practises are now banned, the issues surrounding past exploitation of animal resources in the Svalbard area remain a problem. With whale, seal and walrus populations are still far below than they were even two centuries ago (the average age of a Greenland whale). The population of polar bears are locally recovering from the major culls of the 1960s and 1970s that came about due to the availability of snow scooters; however, the polar bear remains threatened at a global level, due to unsustainable levels of killing by humans and marine water pollution. There are a wide variety of birds in Svalbard including puffin, Arctic skua, kittiwake and fulmar, many of which populations are being monitored. Physical geography Lands The main islands of Svalbard
