Tidal constituents from 690 tide stations in Japan and 4365 tide stations in the world are included. The Catalogue covers Name of station, location, observation period, number of constituent and distribution charts.
This catalogue contains data distribution charts, cruise ID, location, observation period, area name, number of tidal current constituent, observation depth, area code by cruise ID and by area code.
This catalogue includes data distribution chart by season, cruise ID, observation date and time, location.
This catalogues provides data sources by country, distribution chart in 10 degree squares, distribution chart in 30 minute squares by annually, monthly.
This catalogue is for J-BIRD(JODC Bathymetry Integrated Random Data Set) which contains depth, contour, low tide line, coastal line.
Those data was retrieved from MGD77 data file and digitized from charts.
