The coastal zone and shelf of Crimea are the objects of long-term comprehensive research predetermined by the significant role these zones play in the economic life of the peninsula. The purpose of the research is to identify trends in inter-annual variability in the structural and functional characteristics of the pelagic community. Data on remote sensing (from satellites), in situ measurements (on board a research vessel) and computed parameters were employed to identify the variability of physical and biological characteristics of the Crimean shelf waters from 2010 to 2020. It was shown that after the environmental cataclysms of the 1990s, associated with shelf eutrophication and trophic impact of plankton invasive species, the planktonic community entered a period of relative stability. The inter-annual variability of its key structural and functional characteristics (namely, phytoplankton biomass, the intensity of its bioluminescence, zooplankton biomass, net primary production and the ratio of production to biomass) could be characterized rather by inter-annual fluctuations due to hydrophysical dynamics than statistically significant trends of long-term variability. The hydrophysical dynamics was assessed by two parameters: the kinetic energy density and cross-shelf mass transfer in the upper layers.
