The report details the procedures developed for the explosion program and gives the reliability of the calibration program. The explosive used was 120,000 lb of high-energy composition B packed in 50-lb cubical cans, which was shot in ten 5.2-ton, six 1-ton and one 1.5-ton packages. These charges were exploded in a network designed to provide optimum recording on the ocean-bottom instruments and minimum damage to marine life. The shots were restricted to the following conditions daylight hours, 2 mi or more from any approaching vessel, a minimum of 13000 fm of water depth, andor more than 100 km from land. The operational procedure gave good data results. The ships rigging contributed greatly to the programs success. An A-frame and crane combination is recommended for future operations.
