OSTI ID:6471226
This patent describes a method of marine seismic exploration of the earth strata beneath a body of water. It comprises: generating in the body of water downwardly travelling compressional waves and sensing at the interface between the body of water and earth strata upwardly travelling reflected shear waves that have been converted at the earth strata from the downwardly travelling compressional waves.
