Buried tunnel valleys off the Northumberland coast, Western North Sea

Abstract

A series of deep, steep-sided, probably linear erosion hollows is described from the East Bank area on the northwestern side of the Dogger Bank, off the Northumberland coast of England. These hollows are infilled with bedded sediments and the whole sequence overlain by thick surface sediments with large linear banks. It is concluded, after a comparison with similar features from the western North Sea, that the East Bank hollows are buried tunnel valleys, which were excavated by sub-glacial streams near the edge of the Weichsel ice sheet, which deposited the Dogger Bank terminal moraine.
