“…This is caused by the smallness of the body tide, which makes the ocean tide loading relatively large. These values are, within the formal errors, in agreement with Melchior et al (1970) and Moens (1976).…”

“…The Longyearbyen phasor plot for M 2 is similar to that of Moens (1976) who used an ocean tide map he compiled out of data found in the literature. For this harmonic he computed an ocean tide loading amplitude of 2.35 μgal and a phase of 142.5°, which is remarkably close to the values obtained with modern ocean tide models.…”

Summary Tidal gravity observations at Ny‐Ålesund on Spitzbergen, made with a LaCoste & Romberg gravimeter with electrostatic feedback, have been used to assess the accuracy of ocean tide models in the Nordic seas. Eight ocean tide models have been used to compute the ocean tide loading at Ny‐Ålesund. The station is very close to the coast and therefore experiences a significant direct gravitational attraction of the nearby tidal water mass. For the bay adjacent to the station, the model values have been replaced by the tide gauge values and a special effort has been made to fit the models correctly to the coastline. The ocean tide models for M2 and O1 have also been compared with observations made over 30 years ago at Longyearbyen, Spitzbergen, with Askania gravimeters. The comparisons of the tidal gravity observations with computed ocean tide loading show that for the harmonic M2 the phase lag of the ocean tide model of Schwiderski and the local tide model of Gjevik et al. are wrong by +15° and −5° in the Norwegian Basin. For the harmonic S2, the models FES94.1, GOT00.2 and Schwiderski give a poor fit to the observed tidal loading at Ny‐Ålesund because of phase lags that are too large in the Norwegian Basin by ∼10°. FES94.1 and GOT00.2 also have S2 amplitudes that are ∼5 cm too large in the Norwegian Basin. For N2, FES94.1, FES95.2, GOT00.2 and Schwiderski have phase lags that are ∼10° too large in the Norwegian Basin and FES94.1 and 95.2 also have N2 amplitudes that are 2–4 cm too large in that region. Overall, for these three harmonics the global model FES99 gives the best fit to the tidal gravity observations at Ny‐Ålesund and this agreement is even closer than that obtained using regional Arctic Ocean tide models.

“…Chiaruttini (1976). The global M2 oceanic model by Hendershott (1973) is used for the North and South Atlantic, Pacific and Indian Oceans, together with the M2 model of the Arctic Ocean by Moens (1976) and with the M2 local models of the Mediterranean ( B a a et al 1973), Adriatic (Polli 1959), Aegean (Livieratos & Zadro 1977) and North Sea (Doodson & Warburg 1941). We have not considered the Baltic and the Black Sea tides since they are very modest (Defant 1961 ;Zadro 1976).…”

The expectation for high accuracies in laser ranging in the years to come and the increasing geodynamical implications in satellite geodesy require the investigation of the effect of timedependent geodynamical phenomena on the laser-ranging sites. In this paper we evaluate the radial and horizontal displacements of the surface of the Earth and the gravity perturbation due to the loading effect of the M2 oceanic tide for 13 European laser-ranging sites. Most of them are situated in coastal regions.
