Estimation of seawater movement based on reflectors from a seismic profile

Seismic oceanography is a new cross-discipline of reflection seismology and physical oceanography.The biggest difference between seismic oceanography and traditional reflection seismology is its re-search object of time-varied seawater.How to estimate the temporal variations of reflectors in water structure and make some corrections in seismic data are basic problems in seismic oceanography research.Here a method of estimation for seawater movement is provided based on the reflectors.The application results of this method to the simulated and field seismic data turn out to be accept-able.As compared with the previous research,this method has the advantages of low-dependence on migration velocity and dip of reflectors,and it is very suitable for correction in a spectral analysis using seismic data,which is very useful in the research of ocean energy budget.
