Sea level variability at the Lithuanian coast of the Baltic Sea
The aim of the paper is to analyse the sea level variability at the Lithuanian coast during the last 100 years using all data available in Lithuania. The analysis, based on sea level data of the Klaipeda Strait for 1898–2002, clearly shows that the long-term sea level increased by about 13.9 cm. Fur...
