HC Deb 05 March 1971 vol 812 cc551-2W
Mr. Laurance Reed

asked the Secretary of State for Trade and Industry whether, in view of the growing number of accidents, the deepening draught of larger tankers, abnormal tide surges and shifting sandbanks on the sea bottom he will now initiate a comprehensive precision survey of the English Channel and the southern part of the North Sea.

Mr. Ridley

Survey work by the hydrographer has been going on and is continuing but international co-operation will be necessary for much of the area involved.
