Abstract : This report describes the development of an Underwater Laser Surveying System usable by two divers for plot layout, bottom contour mapping and other underwater surveying missions. The portable cold-cathode argon laser is the central element to the system. The supporting test program demonstrated the feasibility of the system for plot layouts to 6 inch accuracy and contour elevation to 1.2 inch accuracy over ranges of up to 100 feet. Operating procedures and maintenance instructions for the system are also included. (Author)
