Thirty-eight TNT ant 18 HBX-3 charges weighing one, eight, and fifty pounds were fired at depths betweeen 500 and 14,000 ft; pressure-time data were measured directly above at 185-ft depth. The shock wave peak pressure was independent of depth and decayed with reduced range as in the shallow water case. Durations were a function of depth alone. Empirical equations were derived which show that all other pressure-pulse characteristics can be expressed as functions of depth as well as range. Values obtained for HBX-3 here gave the same ratios to TNT values as previously found in shallow water.
