Abstract

Here, the most recent observational records are analyzed for 19 large rivers encompassing the entire Arctic region over the period 1977 to 2007. Trends in total annual water discharge, melt month and peak month discharge are calculated for individual systems based on records with monthly time resolution. An increase in annual discharge over the entire region is observed over the last 30 years. Melt month discharge increases considerably, whereas peak month discharge is reduced. The AA. attribute the considerable change in the melt month to a shift in snowmelt in the drainage basin
