The Dogger Bank is a topographic feature in the North Sea off the east coast of England. At 20 fathoms depth, it is 160 miles long, up to 60 miles wide, and stands at least 60 feet higher than the sea floor. Recent borings have yielded faunal assemblages and other data which, taken with seismic refraction values, indicate a Pleistocene age for the uncompacted sediments of which it is composed. It is most likely a moraine rather than the seaward extension of a ridge of Mesozoic rocks. Seismic data and faunal lists are included.
