Abstract

A motion controllable towed vehicle housing an acoustic Doppler current profiler, CO₂ analyzer and sensors for other physical and chemical measurements in the upper ocean mixed layer is being developed. The length of the towed vehicle is 3.84 m, breadth is 2.26 m, height 1.4 m and weight in air is 1000 kg, and the maximum submersible depth is designed as 200 m which is enough to research the ocean mixed layer. The data obtained are sent through a towing cable and analyzed by computer in real time on the mother ship
