Wyville-Thomson back
The Wyville-Thomson Ridge is a sea ridge about 200 kilometers long from west-north-west to east-south-east between Scotland and the Faroe Islands . It is part of the Greenland-Scotland Ridge and separates the cold Norwegian deep sea basin from the warmer waters of the North Atlantic. To the east of the ridge, the water temperature at 1000 meters is −1 degrees Celsius, to the west it is 7 degrees.
It rises to a depth of about 620 meters between the 1000 to 1700 meters deep Faroe-Shetland Canal in the east and the Rockall trough up to 1,500 meters deep in the west. It is named after Charles Wyville Thomson , who was the first to research it.
A smaller part of the deep current flows over the ridge, allowing cold, dense water from the Arctic Ocean and the European North Sea to flow back into the Atlantic to compensate for the near-surface North Atlantic Current.
