    3D Seismic Oceanography: The New Frontier in Ocean Water-Column Exploration

    Seismic oceanography is a newly-introduced technique that links exploration seismology and physical oceanography. It consists of the application of the multi-channel seismic reflection method, commonly used in the oil and gas industry to image the subsurface geological structure, to the investigation of the fine structure of the ocean interior. Seismic reflection sections provide high quality images of the oceans fine structures with higher vertical and horizontal resolution and complement conventional physical oceanography measurements and logs. These images consist of seismic reflections that occur and are recorded whenever a seismic wave traveling in a heterogeneous media encounters interfaces between different water layers and is reflected back to the surface and recorded by special receivers. This talk will report the implement of a three dimensional (3-D) seismic study to better image the ocean interior. A very large seismic data set collected from the Mississippi canyon in the Gulf of Mexico is used to produce the 3-D seismic images of the ocean interior. The initial images obtained using massive hardware/software efforts exhibit promising results for further studies.
