Abstract

The underwater survey equipment is mounted on a special rectangular frame with retracting struts (8) at each corner. The edge members of the frame can be supplied with air to float off the bottom while a servo mechanism twists the frame to advance it in any selected direction. Each side is supplied with air independently so that one side of the frame can be made to remain on the seabed while the frame twists and moves laterally. The working survey tools are attached to a trolley which moves over the frame.
