Region of the Gulf of Bothnia separating the Bothnian Bay from the Bothnian Sea
Kvarken (Swedish: Kvarken, Norra Kvarken (as opposed to South Kvarken); Finnish: Merenkurkku, lit. 'throat of the sea') is the narrow region of the Gulf of Bothnia separating the Bothnian Bay (the inner part of the gulf) from the Bothnian Sea. The distance from the Swedish mainland to the Finnish mainland is around 80 km (50 mi), while the distance between the outermost islands is only 25 km (16 mi). The water depth in the Kvarken region is only around 25 metres (82 ft). The region also has an unusual rate of land rising at almost 10 mm (0.39 inches) a year.
