Аннотация: With reference to 2001-2005, the fluxes of dissolved organic matter (DOM) are analyzed in a water stream of the northern taiga subzone of continuous permafrost. Dynamics of hydroclimatic parameters is shown during a frost-free period. It is found that, in spite of a potential decrease in the DOM concentrations with the increased thickness of a seasonally thawed layer, one observes their direct dependence on the precipitation amount and part that enters the water stream. Seasonal variations in the DOM qualitative composition are determined. The basic DOM part exported from the watershed is observed during the regimes of a maximum water content (spring flooding and floods). В© Allerton Press, Inc. 2007.
