John Hughes Clarke
Prof. John Hughes-Clarke joined the departments of Earth Sciences and Mechanical Engineering in the Fall of 2015. His primary fascination is with marine sediment transport, particularly in deep water. To investigate these processes, he has specialized in the use of acoustic swath sonar systems. His original exposure to swath systems was in 1984 looking at the record of the 1929 turbidity current. Since that time he has increasingly focused on the information content available from those systems (bathymetry, seabed and water column scattering). Since 1991, he was part of, and for the last fifteen years the chair of, the Ocean Mapping Group at the University of New Brunswick in Canada. At UNH his predominant role is as part of the Center for Coastal and Ocean Mapping where he teaches, supervises and conducts research in ocean mapping.
