Nutrient cycles in the Arctic
A new project – Nutrient cycle – linking the Atmosphere, Terrestrial, Marine and Glaciological flagship programmes in Ny-Ålesund – aims to strengthen this collaboration between researchers and research groups even further. The projects has received funding from the Research Council of Norway through the Svalbard Strategic Grant programme.
The aim of the project is to increase our understanding of perturbations in nutrient cycles in the Arctic linked to ongoing environmental change. With nutrient cycling being a component in all parts of the ecosystem, a cross-disciplinary and cross-flagship approach is needed to build a comprehensive understanding of the different mechanisms involved.
The project will present an overview of current knowledge, identify gaps and develop hypotheses and research questions to be addressed through a joint effort from all four flagship programmes.
Field measurements, remote sensing data and modelling from researchers from a wide range of fields, from multiple institutions and from several locations on Svalbard, will provide key input to these processes.
A series of activities within the framework of the project, such as keynote seminars, a workshop in Italy, and a series of writing workshops, will lead up to a series of scientific publications.
