Since the launch of TOPEX/POSEIDON and other succeeding satellites, the study of ocean tides has been advanced significantly. Many global tide models have been developed that produced tide information for user applications. Most of the models and outcomes are freely available for download over the internet and have been extensively validated against altimetric, and coastal and pelagic tide gauge data. The global tide models perform well, and are very similar to one another (within few cm) in the deep ocean, but can be very different in coastal and shallow shelf regions (Shum et al. 1997, Lyard et al. 2006). A large number of tidal atlases were developed from the tidal hydrodynamic equations and data assimilation that can be used as boundary condition for coastal models (Examples: NAO, Japan, ADCIRC USA, FES2004, France. etc..). Further work is needed to produce more accurate tide information in coastal waters to meet the requirement of the users. Korea Hydrographic and Oceanographic Administration(KHOA) is interested in securing more accurate tide information for the coastal waters of Korea for various marine operational services. It is a common desire of all the coastal countries around the world, which is a challenging task that can be achieved effectively through global and regional cooperation. To synthesize tidal information accurately for shallow water where the need and application of tide information is most urgent, the followings steps and cooperation are necessary: Accurate global tide model and generation of global tide information to be used as boundary condition for regional model. Suitable tide model and proper method of data assimilation that can produce tide information for the coastal waters by making most of tide observation data. Coastal Tide model must be accurately and easily nested or interfaced to the global tide model to take advantage of boundary conditions. High quality water level observation data both from satellite remote sensing and in situ. water level observation for the regional seas needed in data assimilations. Accurate bathymetry data Accurate tidal information in coastal waters is the basis of operational oceanographic systems to provide useful marine information to the local users. This is a common need of all the coastal countries, yet most coastal countries do not have sufficient capacity or resources to carry out such a challenging task independently. Coastal tidal modeling can be more efficiently carried out through global and regional cooperation under the leadership of GOOS. Such a cooperative project on coastal tidal modeling is most suitable as a GOOS pilot project as it is a global task that requires technical support from advanced countries and participation of coastal countries with tide observations and bathymetry data. The outcome can be shared by the all coastal countries as basic information for coastal services. Since most of the previous global tide models and the outcomes are open to the public, international cooperation would be feasible. Such pilot project can be initiated with different stages: globally as a global GOOS and regionally as regional GOOS. Such contribution of advanced countries would be most helpful for developing countries and would be a good example of promotion of GOOS. The feasibility of this project to initiate as a GOOS Pilot Project can be discussed at GSSC Meeting. 2 8 z*vBH!OJQJ-:;8CJ65PJ^JaJ]\OJQJ2 z*vB!VV & FV & FV & FVVVVV $a$ & FA$ $a$ & FA$ $a$ & FA$ $a$ & FA$:.
