Abstract
WORK on the geology of the floor of the southern North Sea, under a Department of Scientific and Industrial Research grant to the University of Hull, is now in its second year. It has been carried out with a chartered 110-ft. Diesel trawler, using a 10-cwt. gravity corer for sampling, and a continuous reflexion profiler for recording structures in the rocks below the sea bed and the thickness of superficial deposits. The profiler consists of a 1,000 W-sec Edgerton boomer and a directional hydrophone and amplifier of the type developed by the National Institute of Oceanography1. It gives a penetration of about 900 ft. below the sea-floor in favourable circumstances.
