Underwater shock waves generated by explosive removal of a hydrocarbon production platform from the Gulf of Mexico were monitored. Twenty- six Composition B charges were detonated inside bottom penetrating support members at depths beneath the sea bottom ranging from 8 to 26 feet. Charge weights ranged from 25 to 50 pounds. Twelve tourmaline gauges were placed at three water depths at each four ranges from each detonation. This data report summarizes the observed characteristics of the underwater shock waves transmitted into the surrounding water. Similitude equations are developed from which tentative predictions may be made for similar explosive removal operations under other conditions. No conclusions are drawn about the effects of shock waves on marine life forms that may be in the neighborhood of such explosions.
