Sea Surface Reflection Coefficient Estimation

Sea surface reflection coefficient estimates are obtained from imaged sea surfaces by applying an imaging technique that is based on decomposed wavefields acquired by dual-sensor towed streamers. The accuracy of this technique in the case of imaging has been demonstrated employing controlled data scattered by realistic time-varying rough sea surfaces (e.g., Pierson-Moskowiz sea surface). The scattered data was computed based on the Kirchhoff-Helmholtz integral. Here, the feasibility of recovering sea surface reflection coefficient estimates from deterministic and realistic sea surfaces is demonstrated. First, using existing studies, the sea surface reflectivity is benchmarked. Subsequently, sea surface imaging was employed to demonstrate the feasibility of recovering the sea surface reflectivity from marine seismic data.
