摘要: During recent years the accurate measurements from TOPEX/POSEIDON satellite have improved global ocean tide models considerably. However, these are still not enough on continental shelves for detailed oceanographic studies. The need increasing accuracy in shelf regions calls inclusion of more than just semidiurnal and diurnal constituents future models. This is because a considerable part tidal variability caused by shallow water constituents. One example M4 constituent, which exceeds 50 cm at several locations northwest European shelf. So far, has been considered resolving constituents, mainly owing to its coarse ground track resolution. Reliable empirical estimates major can be obtained combining along-track crossover observations. Estimates shelf, M4, M6, MS4, presented this study compared with gauges existing hydrodynamic
