The paper considers a previously unobserved and unmentioned in scientific literature winter bloom of coccolithophores in the eastern part of the Black Sea, identified via satellite data. Until now, according to field and satellite observations, the regular bloom of coccolithophores is observed in the Black Sea in early summer. It begins in May, reaches its peak in June and ends in July. We show that the signatures of intensive coccolithophores bloom are present in satellite images obtained over the eastern Black Sea starting from January 10, 2019. The bloom has been going on for a month already; it can be observed in the cloud free images of satellite sensors of optical range, but its area is gradually reducing. Coccolithophores participate in carbon exchange between the ocean and the atmosphere and play an essential role in the process of absorption of inorganic carbon from the atmosphere. The problem of determining the basic patterns of coccolithophores variability in seasonal and climatic aspects has not been resolved so far. Revealing the fact of intensive coccolithophores bloom in the cold period of year should contribute to the understanding of this phenomenon.
Keywords: Black Sea, coccolithophores, coccolithophores bloom, vortex structures, satellite monitoring, MODIS Terra, OLI Landsat-8, information system See The Sea
