Kolbeinsey (or, Kolbeinn's Isle, Seagull Rock, Mevenklint, Mevenklip, and Meeuw Steen)[1] is a small islet 105 kilometres (65 mi) off the northern coast of Iceland, 74 kilometres (46 mi) north-northwest of the island of Grímsey. The island is the northernmost point of Iceland and lies north of the Arctic Circle. A basalt landform, devoid of vegetation, it is subject to rapid wave erosion and, based upon rates of erosion data from 1994, is expected to disappear in the near future, with an estimate around the year 2020.[2] However, as of August 2020, a small part still remains visible during low tide.[3]
The original size of the island is unknown. When it was first measured in 1616, its size was 700 metres (2,300 ft) from north to south and 100 metres (330 ft) east to west. By 1903, it had already diminished to half that size. In August 1985, the size was given as 39 metres (128 ft) across.[2] At the beginning of 2001, Kolbeinsey had reduced to an area of a mere 90 square metres (970 sq ft), which would correspond to the size of a circle of about 10.7 metres (35 ft) in diameter. The island has a maximum elevation of 8 metres (26 ft).
A helicopter landing site was constructed on the island in 1989[2] but efforts to strengthen the island have subsided in part because of agreements with Denmark over limits.[citation needed] It is named after Kolbein Sigmundsson from Kolbeinsdal in Skagafjörður who is said to have broken his ship there and died with his men.[citation needed]
Geology
A submarine eruption was reported in 1999 near the Kolbeinsey Ridge northwest of Grímsey. Kolbeinsey is the only subaerial expression of this portion of the Mid-Atlantic Ridge. It formed during the late-Pleistocene or Holocene. Dredged glass shards indicate submarine eruptive activity during the late-Pleistocene until at least 11,800 radiocarbon years ago.[4]
