The structural characteristics of bacterioplankton were studied in the waters of the Cape`s Nordkap (cut I) and Zuydkap (cut II) of Mezhvezhiy island. Its abundance and biomass in the upper part of the photic layer of coastal and Atlantic waters in cut I was comparable and increased from the late spring to the summer season. Moreover, in cuts I and II, the values of summer maximum corresponded to the zone of the Polar Front and adjacent Arctic waters. By the beginning of the winter season, the level of development of communities in waters of different genesis decreased everywhere, but still did not reach the minimum, observed insummer in layers deeper than 200 m. The structure of bacterioplankton was determined by single cells of the smallest size, mainly of a cocci-form. The arrival of rod-shaped bacteria (contribution to the total biomass could reach 50%) was recorded in the summer period.

Arctic marine ecosystems are undergoing rapid correction in response to multiple expressions of climate change, but the consequences of altered biodiversity for the sequestration, transformation and storage of nutrients are poorly constrained. Here, we determine the bioturbation activity of sediment-dwelling invertebrate communities over two consecutive summers that contrasted in sea-ice extent along a transect intersecting the polar front. We find a clear separation in community composition at the polar front that marks a transition in the type and amount of bioturbation activity, and associated nutrient concentrations, sufficient to distinguish a southern high from a northern low. While patterns in community structure reflect proximity to arctic versus boreal conditions, our observations strongly suggest that faunal activity is moderated by seasonal variations in sea ice extent that influence food supply to the benthos. Our observations help visualize how a climate-driven reorganization of the Barents Sea benthic ecosystem may be expressed, and emphasize the rapidity with which an entire region could experience a functional transformation. As strong benthic-pelagic coupling is typical across most parts of the Arctic shelf, the response of these ecosystems to a changing climate will have important ramifications for ecosystem functioning and the trophic structure of the entire food web. This article is part of the theme issue ‘The changing Arctic Ocean: consequences for biological communities, biogeochemical processes and ecosystem functioning'.
