Abstract : A towed buoy is deployed to a known depth below the surface from a submarine and this depth is maintained by a control system that includes movable fins on the buoy. The movement of the buoy body and the buoy fins are monitored and used to evaluate sea state parameters, such as wave height for example. The tow cable is coupled to the buoy by means that permits measurement of the angle between the cable and the longitudinal axis of the buoy. Cable tension is also monitored to evaluate other surface parameters such as ocean current.
