Arctic hydrology considers the interconnected environmental processes and physical phases of the water present in the Arctic, which is a high latitude region where most water is in a frozen state for nine or more months a year. Of major importance is the vast distribution of snow, ice, and permafrost. Snow, because of its high albedo, has a major effect on local as well as regional climate. In late spring, snow melt leads to a short period of runoff which contributes about 10% of the Earth’s river discharge into the Arctic Ocean. Changes in river discharge along with decreasing sea-ice cover, permafrost degradation, and glacial melting are an indication of the importance of the Arctic in global change.
