The research acknowledges that the ArcticOcean has gained [...] the Arctic. Besides water temperature increase, expanding ocean acidification will pose another threat to pelagic and benthic life in the ArcticOcean. The shift from an ice-covered and cold ocean to an [...] elemental cycling in the surface ocean will alter due to ocean acidification. These environmental changes will have severe consequences for the biogeochemistry and ecology of the Arctic pelagic system. The effects

We also aim at quantifying the contribution of terrestrial organic matter because it represents [...] the effect of global warming on the occurrence of toxic microalgae and phycotoxins in the Arctic. The Arctic region is heavily impacted by global warming, which has an influence on the growth of planktonic
