Isaksen Island

Isaksen Island (Isaksenøya) is a small island in Hinlopen Strait. It is part of the Rønnbeck Islands in the Svalbard archipelago. It lies east of Cape Weyprecht on Spitsbergen.

The island is a low basalt cliff and its highest point does not exceed 5 m above sea level. The closest neighboring islands are Torkildsen Island about 1 km to the southeast and Mack Island about 700 m to the south. The wildlife consists largely of polar bears.

The island was discovered in 1867 by the Swedish-Norwegian polar explorer Nils Fredrik Rønnbeck. The island is named after the Norwegian skipper and ice-pilot Isak Nils Isaksen (1842–1920), who participated in several scientific expeditions in the Arctic.
