ABSTRACT:
A geophone assembly for use in a marine seismic cable to detect converted shear waves reflected from the strata in response to a compressional wave generated in the body of water associated with the strata. The geophone assembly comprises a cylindrical mount that has a central aperture and a geophone positioned in the central aperture. The mount has a plurality of additional apertures that are sized and positioned to accommodate the plurality of stress members in the cable, and the mount is sized and made of a material so that the weight of the mount is sufficient to cause at least the portion of the cable jacket that is adjacent the mount to contact the seafloor.
