PROBLEM TO BE SOLVED: To provide a constitution of an underwater observation device of a mooring system capable of easily and safely recovering the whole measuring device including a sinker from the water, and an easy and safe recovery method. SOLUTION: In the underwater measuring device of the mooring system, a top buoy, a measuring apparatus, an underwater separating device, and the sinker are interconnected through a roping tool. A vessel for storing a rope having a tensile strength corresponding to the sinker weight and fixing it drawably is fixed to a side surface of the underwater separating device. The upper end of the rope is connected to an upper roping tool of the underwater separating device, and the lower end of the rope is connected to a lower roping tool of a separating hook. The separating hook is opened by a signal from the shipboard to release the connection between the underwater separating device and the sinker, and hence the top buoy comes to the water surface. In the recovery method, the whole underwater measuring device is recovered using the coming top buoy as a clue. The rope is wound in a cylindrical vessel without lid or bottom, and its both end surfaces are preferably fixed via wires stretched in a cross shape. COPYRIGHT: (C)2005,JPO&NCIPI
