Abstract

Concerning the studies of ship's motions in a seaway, a wave measuring instrument has been designed by the author for the studies of ship's motions among ocean waves taking the wave to represent the input forces to the dynamical system of the motions. In this instrument, for ocean waves in deep water zone, a radio telemetering system is devised for use in recording and measuring ocean waves using a bamboo stick wave pole. In respect of the measurement of wave heights on an actual sea surface, measuring and recording the vertical distance from a certain point to the sea surface continuously, wave heights and periods and other wave properties should result from analysis of this record in statistical meaning. As to the method of this scheme of measurement, a freely floating buoy has been used, such as the Froude wave pole or WHOI wave pole. The measuring and telemetering apparatuses are attached to this pole. In this paper, general discriptions of a wave pole and of a measuring and telemetering system of ocean waves in deep water zone are presented.
