William W. Sager, Department of Oceanography, Texas A&M University Multichannel Seismic Analysis of Gas Hydrates and Related Geological Structures in the Northwestern Gulf of Mexico William W. Sager, Department of Oceanography, Texas A&M University The geology of the sedimentary wedge on the Northwestern Gulf of Mexico continental margins is a complex interplay of sedimentation, deformation by moving salt, mass wasting of sediments. These factors control the location of gas and gas hydrate deposits. Our project seeks to map the salt, faults, slumps and other geologic features and to learn how these factors affect gas hydrate accumulation and the location of fluid expulsion features. (left) Section of map of depth to top of salt. Warm colors are shallower; (below) Example multi-channel seismic reflection profile (cross section of sediments) Gassy sediments Mass wasting deposits Top of salt reflection Salt diapir
