Popis: The distribution patterns of absolute and specific values of primary production in the upper 10-m layer depending on the physical and chemical condition of the marine environment (temperature, salinity, depth, bottom topography and configuration of the coastline, and nutrient concentrations) were distinguished in the Russian sector in the Gdansk Basin of the Baltic Sea based on long-term research data (2003–2015). Based on the results, the considered water area was divided into five regions: Cape Taran, the base of the Curonian Spit, the plateau of Rybachy, the open sea, and the Gdansk Bay (northeastern part). These regions are characterized by higher correlations of primary production and parameters of the marine environment compared to regression analysis for the regions distinguished by bathymetry. Primary production is the most closely correlated with temperature over the entire water area and with nutrients concentrations in seaward regions.
