Paper Summary
The impact of moving rough sea surfaces on seismic data can only be assessed through proper modelling. Existing seismic data modelling tools assume either flat or frozen sea surfaces. We present a tool for modelling seismic data from a time-varying rough sea surfaces. This is achieved by coupling the up-going subsurface reflection data with the time-varying sea surface reflectivity on a plane interface below the sea surface using integral technique. The algorithm was verified with known analytical solutions for both frozen and moving sea surfaces. Our data examples show that time varying sea surfaces affect reflection signals significantly in comparison to the static counterpart.
