Chlorophyll “a” concentration and light absorption by colored dissolved organic matter in the Black Sea in winter (2018) and summer (2020)
Journal: Fundamental and Applied Hydrophysics
Year: 2025

The study was based on the results obtained during the expeditions of the R/V “Professor Vodyanitsky” — from November 24 to December 10, 2018 (PV105), from June 4 to 24, 2020 (PV113). New data of light absorption by colored dissolved organic matter (CDOM in the winter and summer were presented. In winter, in the sea surface layer, the light absorption coefficients of CDOM ( a CDOM (438)) (0.10 ± 0.015 m –1 ), exceeded summer values (0.062 ± 0.025 m –1 ). There were no seasonal differences in the
