RESEARCH INTERESTS

Seafloor Mapping Use phase difference, multibeam, and high-frequency sidescan sonars to map seafloor acoustic backscatter and bathymetry. Design real time and postprocessing software to quantify and visualize phase difference sonar data. Build and operate new low-, intermediate-, and high-frequency towed bathymetric sidescan sonars. Procure, evaluate, and operate deep and shallow water multibeam sonars aboard the UH research vessel Kilo Moana (AGOR-26). Create large-volume on-line data archives that synthesize existing and new seafloor data in rapidly accessible databases. Fusion of seafloor acoustic data with subaerial and shallow submarine remotely-sensed imagery, topography and bathymetry.

Marine Geology and Geophysics Structure and tectonics of midocean ridges, with an emphasis on the Juan de Fuca, Reykjanes, Kolbeinsey, and Arctic spreading centers. Collection, processing and interpretation of sonar imagery and swath bathymetry to resolve ocean crustal structure, volcanic processes, sediment characterization and distribution, and plate tectonics processes. Submarine volcanic processes at hotspots, midocean ridges and rifted margins. Neotectonic processes along convergent and strike-slip plate margins.
