Arctic-Hycos: The Arctic Hydrological Cycle Observing System [PDF Flyer]
The Arctic-HYCOS is envisaged as a core network for monitoring of the Arctic Hydrological Cycle (AHC) and will serve as a key component within the IPY endorsed project Arctic HYDRA: The Arctic Hydrological Cycle Monitoring, Modelling and Assessment Program. Arctic HYCOS will provide an important benchmark for understanding future changes to the AHC through:
- Operation of regional observing networks and hydrological information systems
- Improvement of methods for hydrological computations and forecasting in poorly gauged basins, thereby contributing to solving scientific as well as applied problems
- Facilitation of international cooperation in studying and assessing hydrological processes in the Arctic.

Hydrological Cycle in the Arctic Region (HydroArctic)
This research program focuses on the Eurasian cryosphere region. The objective is to understand the state and changes of the water and energy cycles in relation to atmospheric conditions and river discharge. In addition to long-term observations at selected locations, the program will involve modeling and sensitivity experiments.

Impacts of Climate Change on Hydrological Processes in the Norwegian Arctic [PDF Flyer]
Due to the sparse station network in the Arctic, hydrological models that describe the water balance of the land surface are necessary for determining the impacts of climate on land surface hydrological processes. A spatially distributed hydrological model has been tailored to water balance simulations in Arctic environments.

Pan-Arctic hydrological and biochemical responses to climate change [PDF Flyer]
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 also feed large quantities of waterborne substances from land to sea. With the Arctic experiencing relatively large climate change effects, the effects on river discharges also modulate 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 result in major shift in the global ocean circulation and temporary slowdown in poleward atmospheric heat transport.

Research Basins in Greenland [PDF Flyer]
Studies in research basins in Greenland include meteorological observations, glacier mass balance studies, hydrological modeling and monitoring of sediment transport. Specific basins include the Mittivakkat glacier catchment on Ammassalik Island and the Zackenberg River drainage basin, both in East Greenland.
