A previous article (Polar Record, Vol 16, No 104, p 7243 5) outlined the current results, principally from polar areas, of the Deep Sea Drilling Project (DSDP) obtained during the cruises of the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES) research vessel Glomar Challenger. An indication was given of the considerable contribution made by DSDP coring to fundamental geoscientific research. At that time only three legs had been completed in high latitudes: leg 12 in the North Atlantic Ocean, leg 18 in the North Pactific Ocean, and leg 19 in the Bering Sea. No drilling had been undertaken in Antarctic waters but the plans for such work were outlined in the article.
