Vesteris Seamount: An enigma in the Greenland Basin
Vesteris Seamount is a solitary submarine volcano located at 73-degrees-30' N, 9-degrees-10' W in the Greenland Basin. Steeply rising from a base depth of 3100 m to a minimum depth of approximately 130 m and striking 030-degrees/210-degrees, the feature lies approximately 300 km east of th...
