This paper presents geocentric sea level changes at the tide gauge station in Władysławowo, Poland. These changes have been calculated from the time series of GNSS and tide gauge observations. For the estimation of the geocentric sea level trend computer software packages Hector, GITSA, GGMatlab, and Statistica have been used. The results show that all the software packages give a similar value of absolute sea level changes in Władysławowo and it is estimated at a rate of around 3 mm/year.

Purpose. The purpose of this study: to reconstruct the vertical movements of the earth crust, crystalline massif of Avalonia is taken as an example, namely in Netherlands according to tide gauge observations during 1900-2012; to investigate the change of kinematic parameters of the crystalline massif, where the tide gauges, selected for the study, are situated, depending on the average epoch of the observation period t0 and averaging the results of tide gauge observations Δt. Priori assumed that the crystalline massife is a hard tectonic block with linear field of vertical velocity.

Purpose. The purpose of this study: to reconstruct the vertical movements of the earth crust in northern parts of Europe, according to long-term tide gauge observations; to investigate the change of kinematic parameters of the crystalline massif, where the tide gauges, selected for the study, are situated, depending on the average epoch of the observation period t0=1958, 1963, 1968, 1973 та 1978 years and averaging the results of tide gauge observations Δt=60 years. Priori assumed that the crystalline massife is a hard tectonic block with linear field of vertical velocity. Methodology.
