Using regression analysis, linear regression equations are obtained that link ship measurements of the total suspended matter (TSM) concentration in the surface layer in the northeastern (June 2005-2015) and northern (November 2016, 2017, December 2017) deep-sea parts of the Black Sea and regional satellite (MODIS color scanner) products (the particle backscattering coefficient at 555 nm, the light absorption coefficient of colored detrital matter at 490 nm and the concentration of chlorophyll a). Maps of TSM concentrations in the surface layer of the northeastern and northern parts of the sea are constructed using the measured and calculated datasets. A satisfactory agreement of spatial distributions for measured and calculated TSM data is obtained. Interannual seasonal changes in the measured and the calculated TSM concentrations from satellite data during 1997-2017 are considered. Increased TSM concentrations were noted in June 2012, when extremely strong coccolithophorides blooming was observed in the Black Sea. The difference between the measured and the calculated TSM concentrations during the entire observation period was in the average range of 5-20 %. It is shown that satellite data can be used to study the spatial and temporal variability of TSM.
