Abstract:

The capabilities of two side looking sonar systems were evaluated in waters ranging from 250 to 350 feet. Detected targets were visually examined using underwater television and the ASHERAH submersible. Two ancient shipwrecks were discovered as a result. A stereophotogrammetric mapping system was designed, and tested on the ASHERAH. It was demonstrated that it is possible to map extended areas of the oceans floor using overlap stereophotography without the need for surveyed ground control data. Various photographic techniques submersible handling and logistics problems and underwater viewing systems including viewport optics are also discussed. Author
