Winter CZ: measuring CO2 fluxes and microbiological processes in the High Arctic winter At the Bayelva Critical Zone Observatory (Svalbard)

The forthcoming project "WinterCZ" has been presented at the IASC workshop "ACZON" (Arctic Critical Zone Observatories) that took place in Pisa, Italy on January 11-12, 2023. It describes the major actions and challenges to be taken in the project, that will take place in 2023-2025 at the Ny Ålesund research base in Svalbard. The project is aimed to integrate the existing field instrumentation of the projects CZO@Bayelva and TMPT@CNR_NYA in Ny Ålesund (NO) to fill the knowledge gap on the properties and drivers of winter CO2 fluxes in the High Arctic. IGG-CNR shall install new fixed devices for winter monitoring of soil, snow, CO2 fluxes and microbiological activity in the Bayelva basin, developing data services and data-driven and process-based models. The consortium includes five partners: Institute of Geoscience and Earth Resources of CNR (CNR- IGG); Department of Biology of the University of Naples “Federico II” (UNINA-DB); Alfred- Wegener-Institut (AWI); Queen Mary University of London (QMUL); and University of Cologne (UoC)
