Abstract:

The sound transmission part of the Downslope Conversion Experiment DSCE was conducted during the first two weeks of July 1989 in the area off Northern California, between Pt. Buchon and Pt. Arguello. The track lines for the RV New Horizon were designed so that the ship would sail across the continental shelf and slope in at least four and may be five lines, while towing the sound source. The complete experiment involved pre-modeling of signal propagation, gathering of detailed information about the bathymetry and sub-bottom structure, measurement of environmental properties affecting the propagation medium, propagation of an acoustic signal at determined frequencies and locations, and measurement of propagated signals at receiving sites. The DSCEs goal was to make carefully controlled and well documented measurements of downslope signal propagation. This report represents the data collected during the DSCE and also some of the data collected by other sources before and during the experiments. The data include plots of sound speed profiles from CTD stations RV New Horizon RP Flip temperature profiles from AXBT P-3 flights HLF-3 sound source depth time series and wind time series. Also included are satellite infrared images on the Pacific Ocean area under study.
