This data article contains data on the photosynthetic activity, shares of the main algae groups in the total phytoplankton biomass and the main environmental forces in the Kara Sea. The data were collected from 17 to 29 of September, 2011 in the following different areas: the Kara Sea Shelf with and without river runoff influence, the shelf edge and continental slope. The photosynthetic activity parameters include the relative electron transport rate (rETR) values, the maximum quantum efficiency of PSII (Fv/Fm) and the PB/rETR ratio as photosynthetic performance. The main environmental forces include the average day incident light, salinity and water temperature in the upper mixed layer and dissolved nutrients. The data presented in this article are associated with the research article entitled “Assessment of phytoplankton photosynthetic efficiency based on measurement of fluorescence parameters and radiocarbon uptake in the Kara Sea” (Mosharov et al., 2019). The related research article examines the relationships between biological parameters and with environmental characteristics such as temperature, salinity, incident photosynthetically active radiation (PAR) and nutrient concentration.
