Moskenstraumen

Moskstraumen or Moskenstraumen, also known as the Lofoten maelstrom, is a system of tidaleddies and whirlpools, one of the strongest in the world, that forms at the Lofotenarchipelago in Nordland county, Norway between the Norwegian Sea and the Vestfjorden. It is located between the Lofoten Point (Norwegian: Lofotodden) on the island of Moskenesøya (in Moskenes Municipality) and the island of Mosken (in Værøy Municipality). Moskstraumen is unusual in that it occurs in the open sea, whereas most other tidal flows are observed in confined straits or rivers. It originates from a combination of several factors, the dominant being the strong semi-diurnal tides and peculiar shape of the seabed, with a shallow ridge between the Moskenesøya and Værøya islands which amplifies and whirls the tidal currents.
