Abstract:  The study substantiates the possibility of using open data on hydrochemical indicators from satellite systems. It establishes a seasonal peak of eutrophication in the Barents Sea and reveals a strong correlation between the trophic level and the concentration of chlorophyll a, total phosphorus, and mineral forms of nitrogen. The limited applicability of the trophic level index (TLI) to Arctic waters and a high degree of consistency between the trophic state index (TSI) and the trophic index (E-TRIX) have been demonstrated, providing a scientific basis for their integrated use in the context of the sustainable cage aquaculture development. These findings have significant practical implications for the development of monitoring systems and environmental conservation measures in the Arctic region.
