    Three-Dimensional Seismic Oceanography in the Gulf of Mexico

    Seismic oceanography is a new interdisciplinary science that uses legacy marine seismic data from the oil industry to image the ocean water column like eddies or oceanic internal waves. The imaging is achieved by acoustic signals emitted by air guns, reflected from the ocean, and collected by a hydrophone array towed by a ship. For a ship traveling in the ocean, the temperature-salinity structure of the water column can be imaged from the collected signals with a resolution much higher than traditional oceanography measurements.
    Previous seismic oceanography studies are largely based on two-dimensional seismic images. However, the ocean by nature requires three-dimensional (3D) imaging with high resolution. This talk will report our recent results on the imaging of the temporal and spatial variation of water column fluctuations in the Gulf of Mexico enabled by 3D seismic oceanography.
