Sediment Sound Speed Measurements 'IN SITU' from Bathyscaph Trieste.

Abstract

Use of the bathyscaph TRIESTE has permitted the first deep-water in situ measurements of the speed of sound in sea-floor sediments (other than seismic). Measurements were made at 3 stations off San Diego during August-October 1962, in water depths from 338 to 1235 meters, using specially designed probes which measured sound travel time over a 1 meter path 18 inches below the water-sediment interface at frequencies of 25 kc/sec.; probe accuracy was about + or - 0.5 m/sec. Three additional stations were made with the probes in sand bottoms by scuba diving in shallow water.
