Seafloor Geomorphology, Gas & Fluid, and Slope Failure on the Southern Cascadia Continental Margin

1998

Orange, Daniel L.

Our long term goal is to understand the role of fluid flow and gas migration in the creation and modification of shelf and slope geomorphology. In addition, we are examining the interaction of tectonics, sedimentation and erosion in creating and modifying the morphology, stratal architecture and preservation potential of continental margins. We are examining how hydrogeology, natural gas, and tectonics interact and influence submarine geomorphology by combining seafloor data and subsurface imaging. Our goal is to determine the causes of anomalous seafloor bathymetry and reflectivity, and to relate reflectivity to gas migration, subsurface structure, and consolidation state.
