The Arctic-HYCOS project aims to improve the monitoring of freshwater fluxes into the Arctic Ocean for better climate predictions in the Northern Hemisphere. The project serves as a vital platform for the regular collection and free exchange of Arctic hydrological data among all participants. Main activities include evaluating, maintaining and potentially upgrading existing observational stations.

Network Analysis allow identifying observational stations suitable to evaluate freshwater flux to the Arctic Ocean and Seas and to study changes in Arctic hydrological regimes relative to climate change.
