Loki's Castle (hydrothermal Field)

Loki's Castle (hydrothermal Field)

Loki's Castle is a field of five active hydrothermal vents in the mid-Atlantic ocean, located at 73 degrees north on the Mid-Atlantic Ridge between Greenland and Norway at a depth of 2,352 metres (7,717 ft). They were discovered in mid-July 2008 and are the most northerly black smokers which have been located. They are of geological interest as they are in a more stable area of the Earth's crust, where tectonic forces are less and consequently fields of hydrothermal vents are relatively less common.
