A High Resolution Differential Pressure Gage for Deep Sea Use.

Abstract

The need for a differential pressure gage arose during the development of a deeply towed vehicle for use in the study of the micro-topography of the ocean floor. This 'Deep Tow' is an instrument case designed to be towed from a surface ship at depths as great as 15,000 feet and with as much as 30,000 feet of towing cable. The ocean bottom is observed with a high resolution fathometer mounted on the case and it thus becomes necessary to monitor the vertical motion of the vehicle as the profile is being made.
