Abstract:

Extensive, high-quality, low-frequency acoustic scattering data were collected on the Acoustic Reverberation Special Research Program ARSRP reconnaissance Cruise on the western flank of the Mid-Atlantic Ridge in the summer of 1991. To support the analysis of these acoustic data a geological and geophysical GG survey was conducted in the summer of 1992. Among the data taken in this latter cruise were swath bathymetry, single channel seismics, and sidescan sonar. These data are not only critical to the analysis of the acoustic data, but also in planning a fine-scale GG survey and a fine-scale acoustic reverberation experiment in the region in the summer of 1993. Several sites identified by the previous acoustics and GG cruises are planned for the detailed work in this summers cruises. Among these sites are the ARSRP-designed Sites A and C. Site A is a priority site for the future fine-scale work and C is a site alternate to other priority sites. Presented here are displays of relevant GG data for these two sites with some interpretation and analysis. Bottom scattering, Reverberation.
