The article discusses the preliminary results of a comprehensive study of the ice parameters in the area of Severn Bay and the adjacent waters of the Yenisei Gulf of the Kara Sea during the 2023-2024 ice season, organized jointly with the Non-State Development Institute «Innopraktika». The purpose of the expedition was to determine the ice and metocean conditions that may affect navigation in the northern part of the Yenisey Bay. The research design consisted of regular measurements of morphometric characteristics and physical and mechanical properties of level ice at the reference polygon supplemented by a complex of specialized studies at selected characteristic locations during certain periods of the ice season. Specialized studies included: observations at pressure ice ridges to study their shape, structure, and physical and mechanical characteristics; measurements of level ice characteristics and seawater temperature/salinity on a linear profile traversing the bay; studies of morphometric and physical properties of level ice on several additional polygons inside the bay and on approaches to it; aerial photography of sea ice conditions; placement of marker buoys and thermoprofiling buoys on level ice and pressure ridges. This paper describes in detail the composition and methodology of the studies carried out and gives several examples of the results obtained to illustrate the main research directions. The values obtained are compared with those obtained in similar work carried out previously.
