Tidal Charts of eight major ocean tides (M 2 , S 2 , N 2 , K 2 , K 1 , O 1 , P 1 and Q 1 ) are presented for the global ocean, with special emphasis on the East Asian Marginal Seas. The tidal Charts are produced on a 5′ × 5′ grid from a conventional finite difference hydrodynamical model for the purpose of providing a more reliable set of predictive constants. Preliminary results have shown that the conventional approach can be used to reproduce the tidal distribution of the global ocean and marginal seas together reason-ably well. It is also believed that further improvement with data assimilation can pro-vide more accurate harmonic constants for detiding use, especially for correcting altimetric data for Asian marginal seas.
