Young, D R

This patent describes an apparatus for sea bottom deployment from a marine vessel for detecting the shear-wave velocity component of a seismic wave propagated form a marine seismic source following reflection of the seismic wave from a geologic boundary. The marine vessel including a cable for deploying the apparatus and for electrically conducting the detected shear-wave velocity component signals to the vessel. It comprises: at least one seismic velocity receiver for receiving acoustic velocity shear wave reflections and converting the reflections to electrical signals; a housing enclosing the velocity receiver external to and separated from the cable; ballast means located for causing the housing to rest on the sea bottom and thereby acoustically couple the velocity receiver to the sea bottom; seregated, not helically aligned surface means for the housing for stabilizing the lateral position of the housing; weighted, elastically connected means for acoustically decoupling the housing from the cable; and electrical connector means.
