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.
