Dissolved organic carbon fluxes in a discontinuous permafrost subarctic alpine catchment

Abstract The sources and fluxes of dissolved organic carbon (DOC) were investigated within a subarctic catchment with discontinuous permafrost (Granger Basin, Yukon) from 23 June 2001 to 22 June 2002. During spring freshet, stream DOC increased rapidly on the rising limb of the hydrograph, peaked prior to maximum discharge, then declined exponentially to pre‐baseflow levels while flows remained high. During summer storms, a similar pattern was …
