Abstract

It is need to obtain the hydrologic data including ocean current,wave, temperature and so on in South China Sea. A new profiling instrument which doesn't suffer from nature forces or incidents caused by passing ships is under development to recover data from this area. It incorporates a small, instrumented vertically profiling float attached via an electromechanical cable to a winch integral with the main subsurface flotation. On a pre-set schedule, the instrument float carrying sensors is winched up to the surface and defined by an on-board miniature sonar if there is no ship passing by. It can be immediately winched down to a certain depth if the sonar sensor finds something is coming. Because of logistics, the area can only be visited once for a long time and a minimum of 10 times per day. So the system has been designed to conserve a substantial portion of the potential energy and subsequently use this energy to pull the instrument down.
