Ice scour

Ice scour

Ice scour is a geological term for long, narrow ditches in a seabed, created by the collision of fast ice and pack ice. Synonyms include gouging, ice ploughing, ice score, and Ice Gouge. This phenomenon is common along the northern coast of alaska and in the Bering Sea along its costal waters.

It may also refer to ice sheets in the intertidal, which upon movement of the ice, creates physical abrasion and possible dislodgment of marine organisms.
