A three-band satellite algorithm for retrieval of the bio-optical properties of surface waters, developed for the Black Sea, was adapted to the waters of the Southern Ocean (Atlantic region) on the basis of spectral light absorption coefficients of all optically active components (phytoplankton, non-algal particles and coloured dissolved organic matter) measured during the scientific cruises RV “Akademic Msctislav Keldysh” in austral summer 2020 and 2022. The accuracy of the regional algorithm was estimated by comparison with the in situ data. The advantage of the regional algorithm in comparison with the standard one in the range of low values of bio-optical parameters of water was shown, and an approach to further refinement of the algorithm to ensure correct assessment in waters with a relatively high content of optically active components was discussed.
