Correlation coefficients between the monthly numbers of storm days at Vilsandi and Sorve, and monthly mean sea levels (upper values), and monthly maximum sea levels (lower values) for Estonia in 1966-2011.
The results suggest that in addition to the effect of eustatic rise in mean sea level and its partial compensation by isostatic land uplift, the water level rose by up to 6 cm near the Estonian coast during 1950-2002, probably due to changes in wind climate.
The nearcontinuous data sets of mean sea level values are available since 1842.
As a result of the global sea level rise, the Kronstadt zero is not the present-time mean sea level of this tide gauge.
Thereby, the mean sea level and maximum sea level for Estonia were calculated as the mean for four stations (Parnu, Narva-Joesuu, Rohukula, Ristna) during 1950-2011.
Moving averages of annual mean sea level series show some quasi-periodic 30-50-year cycles, which roughly coincide with similar decadal variations at the Lithuanian (Dailidiene et al.
Yanagi and Akaki (1994) investigated mean sea level variations in the Eastern Asia using observed sea level data of 16 stations from the Permanent Service for Mean Sea Level (PSMSL) during 1950 to 1991.
This report exposed historical trends of global mean sea level from tide gauge records and the average sea level from global satellite measurements (Figure 1.2).
Table 3.1 shows the percentages of missing data and mean sea level rise rate (mm/yr) from the tide gauge stations for each station in the GoT in the period 2001-2010.
