Short summary
Our study links surface sea-ice cover and benthic oxygen fluxes in the Fram Strait via primary production, food supply, benthic community, and their functions. We show that sea-ice cover and water depth are the most important factors influencing the ecosystem. However, in water depths > 1500 m, the effect of sea ice fades out. Further, we discuss primary production and benthic remineralization patterns and developed a potential scenario for the benthic remineralization in a future Arctic Ocean.
