Abstract
Seismic waves are detected for a given seismic prospect with an accelerometer and a hydrophone and the outputs of said accelerometer and hydrophone are combined directly to create a signal for seismic analysis. The accelerometer and hydrophone may be combined physically in a single composite unit for recording the seismic waves or an accelerometer and hydrophone may record the seismic survey independently for subsequent combining of the signals from the accelerometer and hydrophone.
