An experiment was conducted in the Sargasso Sea to measure the effect of refraction on underwater explosion shock waves. Sound velocity profiles were measured during the experiment. Eight-lb and 900-lb charges were detonated at precisely controlled depths. The explosion pulses at the close-in thermocline- related caustic and at the first convergence zone were measured by a vertical array of gages and recorded. The measured shock wave peak pressures, impulses, and energies are compared with what might be expected under isovelocity conditions. Some of the shock wave pulses and frequency spectra are presented. A considerable enhancement of pressures and energies was observed.
