Kongsberg Silver Mines
The silver mines of Kongsberg, in Buskerud county in Norway, constitute the largest mining field in Norway, with over 80 different mines. It was the largest pre-industrial working place in Norway, with over 4,000 workers at its peak in the 1770s and supplied over 10% of the gross national product of the Danish–Norwegian union during its 335-year-long history: over 450,000 man-years were expended in the production.
Svalbard
Since the resettlement of Svalbard in the early 20th century, coal mining has been the dominant commercial activity. Store Norske Spitsbergen Kulkompani, a subsidiary of the Norwegian Ministry of Trade and Industry, operates Svea Nord in Sveagruva and Mine 7 in Longyearbyen. The former produced 3.4 million tonnes in 2008, while the latter uses 35% of its output to Longyearbyen Power Station. Since 2007, there has not been any significant mining by the Russian state-owned Arktikugol in Barentsburg. There have previously been performed test drilling for petroleum on land, but these did not give satisfactory results for permanent operation. The Norwegian authorities do not allow offshore petroleum activities for environmental reasons, and the land formerly test-drilled on has been protected as natural reserves or national parks. In 2011, a 20-year plan to develop offshore oil and gas resources around Svalbard was announced.
Svalbard has historically been a base for both whaling and fishing. Norway claimed a exclusive economic zone (EEZ) around Svalbard in 1977, with of internal waters and of EEZ. Norway retains a restrictive fisheries policy in the zone, and the claims are disputed by Russia. Tourism is focused on the environment and is centered on Longyearbyen. Activities include hiking, kayaking, walks through glacier caves and snowmobile and dog-sled safari. Cruise ships generate a significant portion of the traffic, including both stops by offshore vessels and expeditionary cruises starting and ending in Svalbard. Traffic is strongly concentrated between March and August; overnights have quintupled from 1991 to 2008, when there were 93,000 guest-nights.
