Scholte wave arrivals at two diverse test sites were analyzed with the spectral ratio method to obtain estimates of average shear Q of deep sea bottom sediments. The Scholte waves were generated by bottom‐located explosive charges and recorded on o

SUMMARY A long-line seismic refraction experiment extending to a range of 500 km was conducted in the West Philippine Sea. The refraction data corrected for crustal delays are used to estimate the velocity structure in the upper lithosphere. The seis

Near surface seafloor properties are needed for recreational, commercial, and military applications. Construction projects on the ocean seafloors often require extensive knowledge about strength, deformability, hydraulic, thermal, acoustic, and seism

A technique for inverting marine seismic interface wave data for shear wave attenuation parameters of ocean sediments is presented. Because of the difficulty in estimating spectral ratios of seismograms in the case when multiple modes are present, a

We report results from the analysis of data from an array of Ocean-Bottom Seismographs (OBSs) employed in an array of 150 meter aperture at a depth of 3800 meters off the California coast. The array recorded noise samples four times per day for a mon

The first return of a sidescan sonar chirp contains information about the bottom and immediate subbottom character and roughness. Measured real data from a chirp sidescan sonar are basebanded, producing complex signals. These signals are deconvolved

Low‐frequency broadband (LFBB) sonars have the advantage of penetration into the sea‐floor, thus allowing ensonification of buried targets, but the disadvantage of inferior spatial resolution. Hence, this technology heavily relies on reducing fal
