Relationships between sea water salinity and ${\mathrm{\delta }}^{18}{\mathrm{O}}_{{\mathrm{H}}_2\mathrm{O}}$ measured in (a) Gulf of Bothnia, (b) Gulf of Finland and (c) Baltic Proper. Presented models were applied when estimating ${\mathrm{\delta }}^{18}{\mathrm{O}}_{{\mathrm{H}}_2\mathrm{O}}$ for each area
