The surprise crater was discovered on Earth's unexplored ocean floor.
Sean is interested in tectonic-climate interactions, the role of catastrophism in the geologic record and marine and planetary geophysical imaging at nested resolutions. His current projects include tectonic and glacial interactions in Alaska, geohazards and margin evolution of subduction and transform faulting in Alaska, Sumatra, New Zealand, and Japan, and the geologic processes, environmental effects, and habitability of the Cretaceous-Paleogene Chicxulub meteor impact.
Marine and planetary geophysical imaging at nested resolutions and ground truth through drilling, coring, logging, and sampling.
Tectonic processes, tectonic-climate interactions, and geohazards of convergent margins and transitional tectonic environments.
Role of catastrophism in the geologic record including impact cratering, hurricanes, and tectonic events.
Planetary habitability, impact generated ecosystems, biotic crises.
