Short summary
Aquatic tundra plants dominate productivity and methane fluxes in the Arctic coastal plain. We assessed how environmental nutrient availability influences production of biomass and greenness of aquatic tundra. We found phosphorous to be the main nutrient limiting biomass productivity and greenness in Arctic aquatic grasses. This study highlights the importance of nutrient pools and mobilization between terrestrial–aquatic systems and their influence on regional carbon and energy feedbacks.
