Semme Dijkstra holds a Ph.D. in Ocean Mapping from the University of New Brunswick. He is a certified (Cat A) hydrographer from the Netherlands who has several years of hydrographic experience with both the Dutch Navy and industry. From 1996 to 1999, he worked at the Alfred Wegner Institute in Germany where he was in charge of their multibeam-sonar processing. His thesis work involved artifact removal from multibeam-sonar data and development of an echo-sounder processing and sediment classification system. His research focuses on applications of single-beam sonars for seafloor characterization, small object detection and fisheries habitat mapping.
In 2008, Dr. Dijkstra was appointed a full-time instructor and he has taken a much larger role in teaching courses and in evaluating the overall CCOM curriculum.
