Abstract

Between May and October of 2003, mineral composition of surface (0.5 m deep) and bottom (5.0 meters) waters, at measurement stations in north-western and south-eastern parts of Great Lagoon (Szczecin Lagoon), have been studied. Total concentrations of ionic macrocomponents: Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, SO42- have been determined. Differentiation of ionic composition and changing level of concentrations of ionic macrocomponents in waters, depending on location of measurement station, depth of water sample collection and time of examination, have been proved. Bottom waters in south-eastern part of Great Lagoon had highest salinity level, whereas surface waters in the same location had lowest degree of salinity. Taking into consideration relatively small number of measurements, authors of present paper regard outlined investigations as diagnostic and obtained conclusions as preliminary ones. Towards substantial variability in ionic composition and magnitudes of concentrations, it is practically impossible to forecast and define values of concentrations of individual ionic components and general salinity degrees, basing on chlorides concentrations, what was often pursued, until now.


Key words: freshwater, salination, ionic components, Szczecin Lagoon, Great Lagoon
