Trial of creating of tidal current grid data for the Akashi Strait

Abstract

The Japan Coast Guard Hydrographic and Oceanographic Department has provided data on tidal current, which is one of the ocean currents, as area information （tidal current grid data）. In recent years, technologies related to the ocean have advanced, and new information such as detailed water depth data has been acquired. In addition, the mainstream method of providing tidal current grid data is digital, which has a high variety of information usages from printed matter. The Hydrographic and Oceanographic Department is conducting research to create new tidal current grid data corresponding to these. Between 2019 and 2020, the Akashi Strait was examined as part of first trial at creating tidal current grid data.
