Editing Jan Mayen (section)

===Cold War===
After the war, the meteorological station was located at Atlantic City, but moved in 1949 to a new location. Radio Jan Mayen also served as an important radio station for ship traffic in the [[Arctic Ocean]]. In 1959 [[NATO]] started building the [[LORAN-C]] network in sites on the Atlantic Ocean; one of the transmitters was to be on Jan Mayen. By 1961 the new military installations, including a new airfield, were operational.

For some time scientists doubted that the [[Beerenberg volcano]] would become active, but in 1970 it erupted for about three weeks, adding another {{convert|3|km2|abbr=on}} of land area to the island. It also erupted in 1973 and 1985. During an eruption, the sea temperature around the island may increase from just above freezing to about {{convert|30|C|F|abbr=on}}.

Iceland and Norway had a brief territorial dispute over the island from 1979-1980, with the dispute being resolved with Iceland recognising Norwegian sovereignty over the island.<ref>{{cite web|url= http://gudnith.is/efni/jan_mayen_dispute_24_jan_2013|title= The Jan Mayen dispute between Iceland and Norway, 1979-1981|website=Guðni Th.

Historic stations and huts on the island are Hoyberg, Vera, Olsbu, [[Puppebu]] (cabin), Gamlemetten or Gamlestasjonen (the old weather station), Jan Mayen Radio, Helenehytta, Margarethhytta, and Ulla (a cabin at the foot of the Beerenberg).
