Purpose. The purpose of the work is to analyze the suspended matter (SM) flux in the deep part of the Black Sea, assess its variability and investigate the transformation of its composition under anaerobic conditions based on the data collected in 2021-2022. Methods and Results. The data were obtained by means of sediment traps installed at five horizons along the transect between Cape Chersonesus and Bosphorus Strait in the Black Sea. The automatic deep-sea sedimentation observatory (AGOS) was installed during the 119th cruise of the R/V Professor Vodyanitsky and retrieved during the 124th cruise in 2022. The research covered all the seasons in 2021-2022. To collect the material, two types of traps were incorporated into AGOS: to determine the SM vertical distribution and to study its seasonal variation. The processing of the data was conducted using a uniform methodology, which included filtration, drying, gravimetric analysis for the calculation of suspended particulate matter fluxes, as well as determination of the organic and inorganic carbon contents by the coulometric titration method in the laboratory of Marine Hydrophysical Institute of RAS...
