摘要： PROBLEM TO BE SOLVED: To very easily, precisely and stably obtain marine phenomenon information in real time based on a GPS positioning data.
SOLUTION: A motion displacement caused by an oscillation of a spar buoy upper part is measured time-serially as a three-dimensional position data, by a GPS type motion measuring sensor 2 mounted on the upper part of the buoy, and a pitching amplitude ϕ and a motion period Tw of the spar buoy caused by a wave are found based on the three-dimensional position data obtained time-serially. An approximate value of a wave height Hw is found based on the pitching amplitude ϕ and a numeral value of the motion period Tw of the spar buoy obtained therein, and a wave height of a marine wave is estimated based on a numerical value thereof. This measuring method of the present invention uses an interpolation calculation method by table look-up of a motion characteristic table prepared preliminarily, as a method of finding the approximate value. The marine phenomenon information is obtained very easily, precisely and stably in the real time based on the GPS positioning data, in the present invention. The motion measuring sensor 2 used conventionally for the existing spar buoy is posteriorly attached easily, and a great merit is provided in an aspect of a cost.
