The cross-flagship project “Nutrient cycle – linking the Atmosphere, Terrestrial, Marine and Glaciological flagship programmes in Ny-Ålesund” published a scientific report in Nature last July. The project aims to understand the changing fjords and the effect of these changes on ecosystem processes and functions. For this it uses a measure called “Net Ecosystem Metabolism (NEM)” to get information about the overall functioning of the ecosystem.

“Tracking NEM can indicate the effects of stressors such as pollution or climate change on ecosystem functions and it is helpful in monitoring ecosystems providing knowledge and recommendations for management and conservation practices.”

In order to determine the NEM, one needs data on nutrient cycling for which an interdisciplinary approach is necessary. As a result, 21 people are author of the paper – and all flagship disciplines involved. It shows the importance of cross-disciplinary collaboration on which Ny-Ålesund Research Station aims to further elaborate. Congratulations to everybody involved with this important achievement!
