A set of recent published global ocean tide models and two local ocean tide models are compared in the Nordic Seas with a set of tide gauge observations and with each other. For the M2 harmonic, a mean standard deviation of 23% was found compared with the observed tidal amplitudes. For the other constituents this number is even larger, between 34% and 51%. These differences will, to some extent, average out when the ocean loading is calculated but for the displacement ocean loading at Ny-Ålesund significantly different phase-lag values were obtained compared to those published by the International Earth Rotation Service (IERS).
