Structure of Benthic Microbial Communities in the Northeastern Part of the Barents Sea
The Barents Sea shelf is one of the most economically promising regions in the Arctic in terms of its resources and geographic location. However, benthic microbial communities of the northeastern Barents Sea are still barely studied. Here, we present a detailed systematic description of the structur...

The Barents Sea shelf is one of the most economically promising regions in the Arctic in terms of its resources and geographic location.

Beta- and alpha-diversity analyses revealed a clear difference between the microbial communities of diverse sediment layers and bottom-water fractions.
