The Mohns Ridge is an ultraslow-spreading segment of the Mid-Atlantic Ridge located to the north of Jan Mayen in the Arctic Ocean.[1] It is bounded to the south by the Jan Mayen fracture zone, and transitions to Knipovich Ridge in the north-east.
Geology
The ridge started forming 53 My ago, as the Greenland Plate and Eurasian Plate started separating. Four separate axial volcanic ridges have been discovered along Mohns Ridge.[2]
Notable features
Several active and non-active hydrothermal vent fields have been located along Mohns Ridge. In 2008, a black smoker vent field named Loki's Castle was discovered along one of the axial volcanic ridges in the area.[3]
The Schulz Bank seamount is located on the northern part of the ridge, as Mohns Ridge transitions into the Knipovich Ridge.[4]
