Аннотация: Every year there is a polynya (an opening of water enclosed in ice) near the Strait of Baltiysk in the Vistula Lagoon of the Baltic Sea. This polynya is identified on the radar satellite images: 196 synthetic aperture radar (SAR) images covered the period from 26 December 2010 to 06 March 2017 were analyzed, and on 76 of them polynya was detected. The idea behind the study was to describe this polynya (no analogous studies in literature), to find the main forcing factors of its evolution and to test the null-hypothesis, that polynya is determined by Baltic Sea water intrusions at most and indicates the area where these intrusions penetrate into the lagoon. Statistical calculations of evolving parameters of a stable polynya were made. Сomparing these parameters with the basic characteristics of winter seasons (ice conditions, air temperature, wind), Baltic Sea water marine intrusions (on the bathymetry profile of the lagoon area) and sea level changes we came to conclusion that nevertheless there may be one more factor (surface waves) ceteris paribus (other things being equal) that can control the dynamics of the area of the polynya.
