Research Interests:
Interim Director of HIGP;  Marine geology and geophysics, Remote sensing of the seafloor, Mid-Ocean Ridges, Arctic Basin

Currently my scientific research is focusing on two projects, mapping the Arctic Basin using a swath bathymetry and sidescan system mounted on the hull of a US Navy nuclear-powered submarine, and using photographic and acoustic data from a variety of platforms to map the East Pacific Rise at very high resolution.

The East Pacific Rise (EPR) project has two principal objectives: (i) to map lava morphology and flow distribution to understand the recent (~30ka) volcanic history of EPR axis and crestal plateau in the region of the 1991 eruption and (ii) to examine the balance between tectonic and magmatic processes on the EPR crestal plateau through the investigation of fracture and fault distribution along and across the axial flank.

The objectives for the Arctic project are much broader largely because the Arctic, with its permanent pack ice cover, has only been sparsely mapped. Goals for this project range from searching for evidence that the Arctic Ocean was once covered by a thick sheet of ice to documenting tectonism and volcanism on the Earth's slowest spreading mid-ocean ridge (Gakkel Ridge) to investigating the correlation between seafloor topography and physical and biogeochemical water properties.
