Wyville Thomson Ridge

an underwater ridge between the Faeroe Islands and the northern coast of Great Britain. The Wyville Thomson Ridge is about 100 km long and is situated at a depth of 500 m. It separates the Faeroe-Shetland Channel of the Norwegian Sea, where depths exceed 1,000 m, from the Atlantic Ocean. Warm North Atlantic waters flow over the ridge, except for a thin bottom layer consisting of cold waters of the Arctic Ocean, which flow into the North Atlantic basin. The ridge was named in honor of the naturalist C. W. Thomson.
