Vitter bodden (Hiddensee, Kloster)
The outermost Rügener boddens are characterised by complex dynamics within multiple influencing water-masses: water is partially intruding from the Baltic Sea, south and northeast of Hiddensee island (Bachor, 2005). Freshwater surface run off is derived from the NRBC (Helmut Hübel et al., 1998) (Fig. 6). The bodden is further susceptible to large-scale water exchange with eastward parts of the bodden coast, via the Strela Sound (Birr, 1988; U. Schiewer & Gocke, 1996).
At Vitter Bodden (Hiddensee/Kloster; sampling point I), water isotope data exhibit similar seasonal trends than at the Schlei and DZBC sampling spots (Fig. 6). The salinity measurements showed variable values in the sampling period (18th March 2020 – 3rd March 2021), ranging from 7.5 to 11.2 psu (Fig. 6). Similar as in the outer boddens of DZBC, salt water intrusion events (Fig. 3) are the reason behind maximum salinities in February 2020 and 2021. Fluctuating values at the end of the time series are probably influenced by the partial appearance and melting of an ice-cover across the boddens in February 2021.
