Geomorphology of Headless Submarine Canyons: Prediction of Slope Failure,Sediment Strength and Pore Pressure Gradient, and the Regular Spacing of Submarine Canyons

摘要

The long term goal of this project is to understand the interaction betweentectonic and hydrologic forcing and the resultant creation and modification of seafloor geomorphology. The initial objective of this project was to ground-truth the hypothesis that there is a causative relationship between geomorphology and fluid expulsion at the seafloor. Once that relationship was established, we sought to determine the hydrologic and geotechnical state of the venting and non-venting regions. The hydrologic and geotechnical data can be used together with the seafloor observations to model slope failure.
