Abstract

New detailed results on seawater salinity in the shallow part of Puck Bay (Puck Lagoon) obtained during the summer of 2020–2022 are presented. Water with salinity >7.5 g∙kg−1, even up to 7.7 g∙kg−1, occupied most of the lagoon area. The water in Puck Lagoon was clearly more saline than the water in the surface layer in the deep part of Puck Bay. A hypothesis is formulated that the observed increase in salinity in the Puck Lagoon was caused by sea surface evaporation when precipitation was distinctly reduced.
