The abundance and biomass of picophytoplankton, the total concentration of chlorophyll “a”, and the contribution of the picofraction to chlorophyll “a” were studied in the Laptev Sea in 2017. These were the first data for the western sea area. An increase in picophytoplankton abundance in the eastern part of the sea in comparison with that in 1991 was not revealed. The contribution of the picofraction to chlorophyll “a” was the highest (to 56%) in areas with a low total concentration of chlorophyll “a”.
