Survey on the method of creating a tidal current harmonic constants data set.

Abstract

Sea current information is used in a variety of fields, including navigation safety, marine economic activities, marine environment conservation, and marine leisure. The Japan Coast Guards Hydrographic and Oceanographic Department has been conducting ocean current observations, tidal current observations, coastal current surveys, and so on to collect information on ocean currents, and has been publicizing the results in order to contribute to the public. In this paper, a technique for simulating tidal current, one type of the ocean current information, is reported. In order to make it a data for preparation in the research of 2018, we investigated the method of creating a tidal harmonic constants data set, and report the results.
