Abstract:

The Oregon State University OSU Tidal Inversion Software OTIS is being automated, tested and used to generate tidal solutions in the East-Asian Seas EAS region. This effort was undertaken to improve the tidal solutions within a relocatable version of the Navy Coastal Ocean Model NCOM. Tests were conducted within the EAS and with a smaller domain within the EAS, the Yellow Sea, to look at the effects on OTIS of a number of inputs including 1 increasing grid resolution, 2 using more accurate bathymetry, 3 assimilating International Hydrographic Office IHO tide station data as well as tidal data derived from the TOPEX altimeter data, 4 increasing the number of representers used for data assimilation, and 5 increasing the number of tidal constituents being solved for. The tidal solutions generated with OTIS were validated against IHO tide station data in the different areas.
