A waterworld of volcanoes



At Loki’s Castle in the Arctic Ocean, researchers from the University of Bergen (UiB) have discovered a so far unknown world of volcanic activity underwater. They hope that this can become Norway’s new national park.

In 2008, UiB researchers discovered Loki’s Castle, a field of five active hydrothermal vents on the Mid-Atlantic Ridge between Norway and Greenland. The field contains rich metal deposits and a unique wildlife.

New discoveries

This summer a team led by the director of UiB’s Centre for Geobiology, Professor Rolf Birger Pedersen, discovered five new hydrothermal vents in Loki’s Castle. The vents were discovered at depths ranging from 100 to 2,500 metres. In this area, which is crucial to Norwegian geology, a new volcanic seabed is formed at a rate of two centimetres a year.
