The taking of submarine oriented cores for use in oil exploration has progressed steadily since 1947, and there are now six vessels engaged in this work on the Pacific Coast. Early coring methods employed divers to assist with the handling of the equipment, but since 1948 a great many oriented cores have been taken without the help of divers in an area extending from Eureka to the Mexican border. Some of the equipment used in this work is briefly described, and some of the operations are shown in colored slides.
