Jan Mayen is a Norwegian volcanic island in the Arctic Ocean, with no permanent population. It is 55 km (34 mi) long (southwest-northeast) and 373 km2 (144 sq mi) in area, partly covered by glaciers. It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a 2.5 km (1.6 mi) wide isthmus. 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. The isthmus is the location of the two largest lakes of the island, Sørlaguna, and Nordlaguna. A third lake is called Ullerenglaguna. Jan Mayen was formed by the Jan Mayen hotspot.
Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is 2,277 m (7,470 ft) high and is the world's northernmost subaerial active volcano. The volcano is topped by a mostly ice-filled crater about 1 km (0.6 mi) wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side.
Svalbard and Jan Mayen is a statistical designation defined by ISO 3166-1 for a collective grouping of two remote jurisdictions of Norway: Svalbard and Jan Mayen. While the two are combined for the purposes of the International Organization for Standardization (ISO) category, they are not administratively related. This has further resulted in the country code top-level domain .sj being issued for Svalbard and Jan Mayen, and ISO 3166-2:SJ. The United Nations Statistics Division also uses this code, but has named it Svalbard and Jan Mayen Islands.
Olav V Land is a peninsula in eastern Spitsbergen Island, Svalbard named after Olav V of Norway. It is covered by the Olav V Icefield, measuring about 4,150 square kilometres (1,600 sq mi).
Barentsjøkulen is a glacier on Barentsøya, Svalbard. The glacier covers an area of about 571 km2 (220 sq mi). It is named after the Barents Island, which again is named after Dutch explorer Willem Barentsz. Barents Island is on the Barents Sea.
Charlesbreen is a glacier in Oscar II Land at Spitsbergen, Svalbard. It is located between Gunnar Knudsenfjella and Vegardfjella, and debouches into St. Jonsfjorden from the south side. The length of the glacier is ten kilometers. The glacier is named after Charles Robertson.
Torellneset is a headland at the southwestern side of Nordaustlandet, Svalbard. The headland is named after geologist Otto Martin Torell. It is located south of the glacier Vegafonna and is the southwestern point of Gustav Adolf Land. Outside the headland is the island of Perthesøya.
Kjerulfbreen is a glacier in Oscar II Land at Spitsbergen, Svalbard. It has a length of about 7.5 kilometers, and is debouching into the Trygghamna bay at the northern side of Isfjorden. The glacier is named after Norwegian geologist Theodor Kjerulf.
Samarinbreen is a glacier in Sørkapp Land at Spitsbergen, Svalbard. It has a length of 14 mi (23 km), and is the northern branch of Mefonna. The glacier debouches into Samarinvågen, a southern bay of the fjord Hornsund. The glacier is named after Samarin, the name of a craftsman, fisherman and member of Arctic expeditions between 1899 and 1902.
Vasil'evbreen is a glacier in Sørkapp Land at Spitsbergen, Svalbard. It has an extension of about twenty kilometers, with several tributary glaciers. It is named after Russian astronomer Alexandr Semenovich Vasil'ev. The glacier has a wide front facing towards the eastern shore of Spitsbergen, including the bay of Isbukta. The southern part of Vasil'evbreen is called Randbreen, located north of Istoppane and Dumskolten, and south of Søre Randberget.
Zieglerøya is an remote island off the headland Andréetangen at the eastern side of Tjuvfjorden, at the southern side of Edgeøya, Svalbard. Total area of the island is approximately 2,8 km2. The island is possibly named after either German Arctic explorer Phil. Alex. Ziegler, or Swiss cartographer Jakob Melchior Ziegler. It is quite low lying, with an elevation of1 metre. It is also known as Ziegler Island.
Rijpbreen is a glacier in Gustav V Land at the northern side of Nordaustlandet, Svalbard. The glacier debouches into Bengtssenbukta, a western branch of Rijpfjorden. The glacier is named after Dutch explorer Jan Rijp.
Besselsbreen is a glacier on Barentsøya, Svalbard. It is the largest offshoot of Barentsjøkulen, reaching down to the sea in the northeast direction, west of the point Kapp Bessels. The glacier is named after German Arctic explorer Emil Bessels.
Freemanbreen is a glacier on Barentsøya, Svalbard. It is an offshoot of Barentsjøkulen, reaching down to the sea in the southern direction, into Freeman Strait. The glacier is named after British Alderman Ralph Freeman. The mountain of Buklerimen separates Freemanbreen from the glacier of Hübnerbreen.
Qvale Island is one of the Rønnbeck Islands in the Svalbard archipelago. It lies northeast of Cape Weyprecht on Spitsbergen. The island is a low basalt cliff and its highest point is only 16 meters (52 ft) above sea level. The closest neighboring islands are Carlsen Island about 350 meters (1,150 ft) to the east and Skipper Island about 2.4 kilometers (1.5 mi) to the west. The wildlife consists largely of polar bears.
Carlsen Island is one of the Rønnbeck Islands in the Svalbard archipelago. It lies southeast of Hinlopen Strait and northeast of Cape Weyprecht on Spitsbergen. The island is a low basalt cliff and its highest point is only 10 meters (33 ft) above sea level. The closest neighboring islands are Qvale Island about 350 meters (1,150 ft) to the west and Nedrevaag Island about 2.4 kilometers (1.5 mi) to the west. There are also some islets to the north and east. The wildlife consists largely of polar bears.
Nedrevaag Island is one of the Rønnbeck Islands in the Svalbard archipelago. It lies in Hinlopen Strait northeast of Cape Weyprecht on Spitsbergen. The island is a low basalt cliff and its highest point is only 17 meters (56 ft) above sea level. The closest neighboring islands are neighboring Simonsen Island about 500 meters (1,600 ft) to the northeast and Carlsen Island about 2.4 kilometers (1.5 mi) to the west. The wildlife consists largely of polar bears.
The geology of Jan Mayen is part of the larger Jan Mayen Ridge, an undersea volcanic ridge that forms the boundary of the Iceland Plateau to the northeast. North of the island, the sea floor slopes steeply, plunging a depth of greater than two kilometers in the vicinity of Jan Mayen Rift Zone. The region is highly tectonically active, at the junction of the European and American plates. This activity produces volcanism and earthquakes on the island itself. Beerenberg, a 2.27 kilometer tall volcano rises on the north end of the island, covered in more than 20 glaciers.
Kjerulf Glacier is a glacier in Jan Mayen. It begins at the Hakluyttoppen slope, in the outer crater edge of the Beerenberg. The Kjerulf Glacier and both its neighbors, the Weyprecht Glacier in the west and the Svend-Foyn Glacier in the east, are the most active glaciers in the island.
Bjørlykkebreen is a glacier in Albert I Land, Spitsbergen, Svalbard. It is a tributary of Lillehöökbreen, and is debouching into the Lilliehöökfjorden. The glacier is named after Norwegian geologist Knut Olai Bjørlykke following a proposal in 1912 by Adolf Hoel who had traversed the glacier in 1909 together with Olaf Holtedahl.
