Thermal regime of the Vistula River mouth and the Gdańsk Bay

Surface water temperature characteristics of the Vistula River mouth and the Gdańsk Bay were determined on the basis of available observations, remote sensing and hydrodynamic models. The water temperature in the Vistula River and the Gdańsk Bay was found to be much higher than the air temperature. In recent decades, the water temperature in the Vistula River mouth and the Gdańsk Bay has increased significantly. It hasbeen determined that water temperature in the bay is affected not only by air temperature, but also by water discharge of the Vistula River and wind.
