Submarine Landslides and Slope Stability

Conditions within subsea sediments determine when, where, and how slope failure occurs. Seismic data is an excellent tool for investigating both sediment and pore fluid characteristics. Using data from the ENAM community experiment we are developing a robust picture of the conditions in and around the Cape Fear and Currituck landslides.

By applying modern processing techniques to legacy data, I have been examining the CO2 storage potential of Mesozoic rift basins offshore the US east coast. Detailed prestack waveform inversion sheds insight into basin compositions, and thus the character of the rock infill and volumetric storage potential.

My research goals aim to map diapycnal diffusivity of meso- and sub-mesoscale ocean structures. Using spectral methods applied to carefully processed seismic data I quantify turbulence around internal waves, rough bathymetry, and eddies. Field sites include the Caribbean, South China Sea, and Adriatic.

Using prestack waveform inversion, my research goal is to detail the distribution of methane hydrates and free gas. Then by leveraging detailed velocity information, move toward making quantitative estimates of hydrate concentration, particularly in coarse grained sands. My study areas have been at Blake Ridge and various sites in the Gulf of Mexico.

Working with borehole geophysicists, I am developing and applying methods to estimate rock properties such as pore fluid pressure, porosity, and hydrate concentrations from inverted seismic data. The aim of this research is primarily to address natural hazards along continental margins.
