Description

There is mounting evidence that the Arctic water cycle may today be experiencing an unprecedented degree of environmental change, including increasing discharges of major rivers into the Arctic Ocean, which feed also large quantities of waterborne substances from land to sea. With the Arctic experiencing relatively large climate change effects, the effects on river discharges modulate also erosion and nutrient release, and associated downstream sediment and solute transport, which affects the biogeochemistry of inland waters as well as of the recipient Arctic Ocean. Increases in freshwater transport to the Arctic Ocean may further play an important role for the planetary redistribution of moisture and capacity to form North Atlantic Deep Water, which may shift the global ocean circulation and slowdown the poleward atmospheric heat transport. The present project aims at: i) quantifying the spatial-temporal distributions of coupled hydrological and biogeochemical change responses to climate change in the Pan-Arctic Drainage Basin; and ii) identifying main data gaps, uncertainties and future priorities in monitoring of the pan-Arctic hydrological system. The research will be carried out in close collaboration with and as integral part of the international Arctic-Hydra research consortium, which is the IPY focal point for integrated studies of continental hydrology, serving as springboard for a longer-term, 10-15 year science agenda.
