The feasibility of obtaining detailed bottom statistics is investigated. It is concluded that the most cost effective method is to use a vehicle towed within 300 feet of the bottom which obtains a profile by means of high frequency sonar and determines its depth by means of a precision depth gage. The track of the vehicle is determined by doppler acoustics. Such a vehicle at present appears feasible although detailed test data on the precision of the depth sensor has not yet been obtained due to difficulties in establishing references pressures to the precision desired. The system as presently configured would be used on a typical oceanographic ship such as the AGOR USNS SANDS. (Author)
