Abstract
Tide gauge records comprise of relative sea level change and vertical land motion, while satellite altimetry provides absolute sea level change in the Earth's center fixed frame. Accordingly, the difference of both observations can be used to estimate geocentric vertical land motion along the coasts. In this paper, the vertical land motion rates are investigated at 13 tide gauge sites along the Black Sea coast by analyzing differences between Tide Gauge (TG) and Satellite Altimetry (SA) observations. Furthermore, the estimated vertical motion rates are compared with those from nearby the Global Positioning System (GPS) measurements. The results show general consistence with the present geodynamics in the Black Sea coastal region. For example, our estimates support the general subsidence at Bourgas and Varna. (C) 2017 COSPAR.
