Geophysical technique to study the subsurface of the earth using sound waves induced by explosives, vibrating devices, or percussive equipment. The reflections of the sound waves from the boundaries of different rocks are measured.
Investigation of the upper- and middle continental slope of the Mississippi Canyon, including the Gulf of Mexico, for the distribution of gas-hydrate deposits with links to a DEM image map, bathymetry data, and research technology.
Links to information on the formation and structure of Chesapeake Bay including online reports, recent field work, field work archives, cooperating agencies, bibliography, and links to articles about other terrestrial impact craters.
Compilation of P-wave data from the Indian subcontinent Deep Seismic Sounding (DSS) profiles that used refraction and reflection techniques to provide an estimate of crustal thickness across the subcontinent.
Integrated shipboard data collection, processing, and archival system for digital sidescan sonar and seismic data used in mapping the inner continental shelf.
Report with preliminary sea floor map displaying submarine rock exposures found along the northern part of Monterey Bay National Marine Sanctuary, extent based on side-scan sonar records, seismic-reflection records, and underwater video.
