Research Interests

My research focus is ocean current circulation along the continental margin, the region from the shore out to and beyond the continental shelves and slopes. Using both traditional tools and the new technologies of satellites and autonomous sampling vehicles I have studied the ocean circulation in the Gulf of Maine, the Brazil Current at tropical latitudes and the shelf and slope circulation between Pt. Sur and Bodega California. In addition I have conducted two studies in the Gulf of the Farallones and studied the California Undercurrent, a current that flows poleward, carrying subtropical water north into the North Pacific. More recently, I worked with the California Coastal Conservancy to establish a network of surface current monitoring instruments that measure coastal ocean circulation along the whole California coast and provide maps and data on the web in near real time. For more information about the monitoring projects I’ve been involved in, please visit:
