The viral and bacterioplankton communities of the Barents Sea were investigated using a combination of methods of electron and epifluorescence microscopy for the first time. The quantitative composition of the communities and the nature of their interactions were also determined. Our study showed that during the summer the abundance and biomass of bacterioplankton reached 0.4–4.0 × 106 cells/mL and 25.09–84.21 mg/m3 in offshore waters and 0.4–1.8 × 106 cells/mL and 19.63–100.19 mg/m3 in coastal waters, respectively. In both regions, the number of viruses (1.7–35.8 × 106 and 14.5–32.4 × 106 particles/mL) exceeded the number of bacteria by 2–31 and 13–60 times, respectively; the average viral production was 0.75106 and 1.74 × 106 particles/mL/day, respectively. The proportion of infected cells in the total bacterioplankton (7% on average) and virus-induced mortality of bacteria (8%) were much lower in offshore than in coastal waters (14 and 20%, respectively).
