Research Interests
Deep Ocean: Mid-ocean microplate tectonics, small and large offset propagating rifts, and hydrothermal venting and other mid-ocean ridge processes.
Shallow Ocean: High-resolution multibeam studies of: 1) benthic habitats of coral reefs and fish; 2) paleoshorelines & sea level rise; 3) scour & burial of mines, artificial reefs, & pipelines; 3) shallow water hydrothermal venting, and 4) paleoshorelines.
Over the past six years, these research interests have been addressed with oceanographic seafloor mapping expeditions to the Gulf of Mexico, Atlantic, Pacific, and Indian Oceans. Analyses of multibeam, magnetics, gravity, side-scan sonar are made in conjunction with insight from a seafloor spreading analog wax model. Current projects include: Plate tectonic reconstruction of the Pacific-Nazca plates, Off-axis volcanism along the Easter Seamount Chain, Deep submersible investigations of exposed oceanic crust, Benthic habitat studies of Pulley Ridge, Florida Middle Ground, and Panama City Beach. Students involved in these projects partake in data collection, data analysis and publishing results (e.g., four of the five publications listed below are first-authored by the student involved with the project).
