Dr. Mountain’s research is at the intersection of geophysics and geology, using marine seismic reflection data to map stratal patterns correlated to core samples. His main interests are documenting the record of Cenozoic sea-level change, the transport of sediments across shelves and slopes, and the control of deep-sea sedimentation by abyssal currents. Understanding these processes illuminates the impact of global climate change on the Earth system at a wide range of scales in both time and space.
