Concept
Jan Mayen (jɑn ˈmɑ̀ɪən) is a Norwegian volcanic island in the Arctic Ocean with no permanent population. It is long (southwest-northeast) and in area, partly covered by glaciers (an area of around the Beerenberg volcano). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a wide isthmus. It lies northeast of Iceland (495 km [305 mi] NE of Kolbeinsey), east of central Greenland, and northwest of Vesterålen, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna (South Lagoon) and Nordlaguna (North Lagoon). A third lake is called Ullerenglaguna (Ullereng Lagoon). Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a microcontinent. Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as Svalbard and Jan Mayen, with the two-letter country code "SJ". Jan Mayen is home to Beerenberg, which is the northernmost active volcano in the world. Jan Mayen Island has one exploitable natural resource, gravel, from a site located 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 long. The coast has no ports or harbours, only offshore anchorages. There are important fishing resources, and the existence of Jan Mayen establishes a large exclusive economic zone around it. Norway has asserted a exclusive economic zone (EEZ) around the island since 1980 encompassing more than a quarter of a million square kilometers of EEZ. The Norwegian Coast Guard is responsible for conducting fishery and other maritime surveillance and enforcement in these waters. Norway has found large deposits of minerals along the Mid-Atlantic Ridge between Jan Mayen and southern Svalbard/Bear Island, including copper, zinc, cobalt, gold and silver.
