Current Research Defining the structure and morphology of the Gakkel mid-ocean ridge (MOR) ; SCAMP sidescan and bathymetry data from the SCICEX1998 & 1999 Arctic cruises. * In collaboration with M. Edwards, B. Coakley, J. Cochran & D. Chayes Web based distribution of scientific data and online database design for multi-disciplinary datasets collected along the world mid-ocean ridge system. * In collaboration with M. Edwards & D. Fornari Investigation of volcanic and tectonic processes along the fast spreading East Pacific Rise (EPR) 9° 44' - 55' N through high-resolution near-bottom imagery. * In collaboration with M. Edwards & D. Fornari
