Bacterial biomass and activity were investigated in deep waters at two sites in the eastern Atlantic, of similar depth (4560–4800 m), but varying in their nutritional status. The Northern (N) site was eutrophic and subject to a strong seasonal input of surface derived organic matter (phytodetritus)...
