Project description

Northern aquatic ecosystems are seasonally variable due to long, cold and dark ice-covered winters as well as 24-hour sunlight during summer. A warmer climate has effects on the extensions and magnitudes of snow- and ice-cover, with shorter duration of ice-cover expected for northern aquatic ecosystems. The ice-cover is important for carbon accumulation (CO2 and CH4), aquatic-atmosphere gas exchange and a number of biological processes. Hence, a changing ice-cover regime will have important implications for the function of northern aquatic ecosystems and for the role of these systems in the global carbon cycle.
