Analysis of Seismic Refraction Data from November - December 1973 Field Trip - Constant Depth Leg.

Abstract

A seismic refraction experiment was conducted, as part of the November-December, 1973 field tests off Daytona Beach, florida. In the seismic experiment reported here, two pound charges were detonated one meter off the bottom and received on a vertical hydrophone array. The experiment was conducted along two legs; a constant depth leg and a leg along a sloping bottom. Along each leg, charges were detonated at ranges from about 1 km to 10 km. The recorded signals along the constant depth leg have been examined and four distinct refracted arrivals have been identified. The travel time versus distance curves for these different arrivals have been analyzed and layer thicknesses and propagation velocities for the different sedimentary layers have been obtained. The data presented here gives a description of the bottom properties that are important in modeling the sound propagation characteristics for this area. (Author)
