The hydrologic cycle and the environment of the Arctic are changing rapidly. There is mounting evidence that the productivity of terrestrial ecosystems, the balance of energy, water, and carbon, and the dynamics of the Arctic Ocean and atmosphere are all likely to be changing due to a variety of environmental factors including greenhouse warming. Water figures prominently in such changes. The stature and relative abundance of plants may be changing, producing new patterns of feedback to regional and global energy, water, and carbon balances. Increases in freshwater transport to the Arctic Ocean may at some point reduce the formation of North Atlantic Deep Water, resulting in a cooling in the North Atlantic region and a reduction in global ocean circulation. Because such changes are of potentially enormous global importance, a better understanding of arctic hydrology is critical.
There are several notable gaps in our current level of understanding of Arctic hydrological systems. At the same time, rapidly emerging data sets, technologies, and modeling resources provide us with an unprecedented opportunity to move substantially forward.
The Arctic Community-Wide Hydrological Analysis and Monitoring Program (Arctic-CHAMP), funded by NSF/ARCSS, was established to initiate a major effort to improve our current monitoring of water cycle variables, and to foster collaboration with the many relevant U.S. and international arctic research initiatives. The first set of projects, funded under ARCSS through the ‘Freshwater Initiative’, links CHAMP, the Arctic/Subarctic Ocean Fluxes (ASOF) Programme, and SEARCH. This poster will provide an update on the establishment of the new Arctic-CHAMP Science Management Office, and an overview of ongoing Freshwater Initiative Projects focusing on the Arctic hydrologic cycle.
