Visualizing underwater environments using multifrequency sonar

This article introduces seabed visualization by describing three case studies that use a high-speed, multifrequency, continuous scan sonar called the Seabed Visualization System. The case studies involve: modeling a harbour wall in Holland, permitting a virtual inspection of the harbour environment; visualizing a sunken military vessel, the SS Richard Montgomery; and visualizing underwater pipelines in Easington, England.
