Benthic macrofaunal bioturbation activities from shelf to deep basin in spring to summer transition in the Arctic Ocean
The aim of this study was to assess bioturbation rates in relation to macrozoobenthos and environmental variables in the Svalbard fjords, Barents Sea and Nansen Basin during spring to summer transition. The results showed differences in benthic community structure across sampled area in relation to...
