Nutrient pathways and their susceptibility to past and future change in the Eurasian Arctic Ocean
Abstract Climate change is altering nutrient cycling within the Arctic Ocean, having knock-on effects to Arctic ecosystems. Primary production in the Arctic is principally nitrogen-limited, particularly in the western Pacific-dominated regions where denitrification exacerbates nitrogen loss. The nut...

Abstract Climate change is altering nutrient cycling within the Arctic Ocean, having knock-on effects to Arctic ecosystems.
