Hydrates and Salt Tectonics

Gas hydrates and salt are ubiquitous in many marine sedimentary basins and are important to carbon cycling, slope stability, and as a potential energy source. We study their occurrences in sedimentary basins with marine seismic data, logs, and cores, and their potential role in submarine landslides. We work closely with Dr. Ann Cook and collaborators at UT Austin and Columbia’s Lamont-Doherty Earth Observatory.
