Project description:
The Arctic already shows many signs of global change, including warming, reduced sea-ice cover, permafrost thawing and related changing in freshwater and organic carbon flux from rivers. It remains to be determined how these changes will enhance or mitigate rates of air-sea CO2 flux and acidification. The aim of this joint project is to describe the ongoing change in the physical and chemical water mass properties off the Bayelva river prodelta (Ny-Ålesund) in response of the thawing permafrost and glacier retreat. Specifically, we will use moored equipment to provide a high-resolution time-series in order to estimate the release of permafrost into the marine environment and how its degradation can increase CO2 levels and the ocean acidification process.
