Winter is the most rapidly changing season in the Arctic, causing widespread responses in freshwater ice and the ecosystems and communities that rely on frozen lakes and rivers. Freshwater ice dynamics—the formation, growth, and melt of ice—not only integrate winter climate conditions, but also impact permafrost, hydrology, greenhouse gas emissions, and human travel and subsistence.
Long-term observations document dramatic changes in ice thickness and breakup timing in lakes and rivers of northern latitudes. Such ice observations come from rigorous programs conducted by government and academic scientists using satellites, in situ sensors, and sophisticated field measurements, but also from lake- and river-side communities, school classrooms, and subsistence-users who watch these changes daily.
Navigating the new Arctic with Fresh Eyes on Ice, a new freshwater ice observation network, revitalizes existing datasets and expands observations in space and time using modern satellite, aerial, and in situ sensing techniques integrated with community-based monitoring teams. Winter field campaigns, dedicated social media and data sharing are connecting communities in boreal and arctic Alaska, making science education and outreach seamless components of this observing network.
