Journal Title: Геодинаміка - Year 2016, Vol 21, Issue 2
Abstract
Purpose. The purpose of the study is to detect and investigate the differences in determining vertical crust movement velocities (VCMV) in Europe applying two independent methods: tide gauge and GNSS-observations. Methodology. As the result of the average crust movement velocity calculation applying tide gauge ( ± ) and GNSS-observations ( ± ) the interpolation of vertical crust movement velocities has been conducted ( and ),at points equally set-along the European coastline (every 10 km), their mean-square error ( and ) has been determined. The research has been conducted separately: one has been based on tide gauge observation and the other has been based on GNSS-observations. Results. Based on processing the results of tide gauge and GNSS-observations the difference (mm/year) between vertical crust movement velocities has been determined. Having analyzed these differences, it has been found that it is typical for the whole European territory. The greatest t value of it is 2.6±0.8 mm/year on the territory of Fennoscandia, the least one is on the territory of the Netherlands (0.6±0.2 mm/year) and the Balkans (0.6±0.1 mm/year). To say, varies from 0.6 to 2.6 mm/year. The mean square error of differences varies from 0.1 to 0.9 mm/year. The average value on the European territory is 1.8± 0.5 mm/year. The results of determination of are summarized in 4 set units: the territories which are almost identical in accuracy of determining the value of average differences. The first unit (I) comprises the territory of Fennoscandia and Central Europe ( = 2.4±0.6 mm/year), the second one (II) comprises the territory of Western Europe (= 0.7±0.2 mm/year), the third unit (III) comprises the territory of the United Kingdom and Southern Europe (= 1.5±0.3 mm/year), the fourth one (IV) comprises the territory of Appenines Peninsula (= 1.0±0.3 mm/year). This component has systematic and constant features in certain areas and is always positive. The main factor causing the appearance of is obviously the increase of absolute global sea level, which is manifestated in tide gauge observations as well as salinity and wind impact. Scientific novelty. The results of the study give the possibility of common balancing of tide gauge and GNSS-observations in order to determine vertical-crust movement velocities along the coastline taking into account relevant systematic error and the possibility to predict vertical crust movement velocity. Practical significance. As the result of the study the systematic difference between the results of the determination of vertical crust movement velocities applying tide gauge and GNSS-observations has been set. Taking into consideration this difference gives the possibility to predict changes of the coastline position and sea level changes. It also presents a significant socio-economic impact on people living not far from the seacoast. Changing the position of the coastline is also significant while designing and constructing hydrotechnical structures and ports at seacoasts.
