Based on the data collected during scientific expeditions of RV “Professor Vodyanitsky” in January, April, October 2016 and July 2017, spatial and temporal changes in distribution of microplankton ATP and&#13;\nchlorophyll α as indicators of metabolically active biomass and its photoautotrophic part, respectively, were analyzed. The heterotrophic-photoautotrophic index (HPI) was calculated from ratios of these biochemical parameters and used to assess the stages of production and destruction suc
