A 2-D tide model of the Gulf of Maine failed to produce accuracies necessary for the de-tiding of Geosat satellite data. A subsequent sensitivity analysis indicated that the model was extremely sensitive to depth. This unusual sensitivity to depth is due to the unique character of tidal resonance in the area. The Gulf of Maine bathymetry must be accurate to within 1-2 meters to achieve tide model accuracies of less than 5 cm. in amplitude.
