... imagery at long range, and Chirp subbottom sonar to provide high resolution profiles in both the near bottom and deeper subbottom. The tow vehicle contains a suite of full-ocean depth instrumentation for measuring various oceanographic parameters and for monitoring vehicle status. Top side systems include...

... ABSTRACT This paper describes several new developments in the evolution of side scan sonar sea bed mapping systems. A new advanced microprocessor-controlled tuning improves record quality. New deep tow vehicles allow for relatively high speed medium depth towing or low speed full ocean depth...

...) acquired near-surface data to 100 meters below the mudline. Deeper geologic structure was provided by 300-joule minisparker and 8-12 kjoule sparker with multifold recording and processing. Improved methods of deeply towed vehicle navigation and winch/cable handling were needed for the survey...
