What country owns Jan Mayen island?

Jan Mayen is a Norwegian volcanic island in the Arctic Ocean, with no permanent population. It lies 600 km (370 mi) northeast of Iceland, 500 km (310 mi) east of central Greenland and 1,000 km (620 mi) west of the North Cape, Norway.

The island is mountainous, the highest summit being the Beerenberg volcano in the north. Jan Mayen Island has one exploitable natural resource, gravel, from the site at Trongskaret.

Other than this, economic activity is limited to providing services for employees of Norway's radio communications and meteorological stations located on the island. Jan Mayen has one unpaved airstrip, Jan Mayensfield, which is about 1,585 m (5,200 ft) long. The 124.1 km (77.1 mi) coast has no ports or harbours, only offshore anchorages.

The only inhabitants on the island are personnel working for the Norwegian Armed Forces and the Norwegian Meteorological Institute. Eighteen people spend the winter on the island, but the population may roughly double (35) during the summer, when heavy maintenance is performed. Personnel serve either six months or one year, and are exchanged twice a year in April and October.
