Positions

Overview

  • 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. His original exposure to swath sonar 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. Since 1991, he was part of, and for the last nine years the chair of, the Ocean Mapping Group at the University of New Brunswick in Canada. He is also a professor in the department of Earth Sciences and is a member of the Center for Coastal and Ocean Mapping.
