Seasonal Variability of Groundwater Contribution to Watershed Discharge in Discontinuous Permafrost in the North Klondike River Valley, Yukon
The objectives of this thesis were: (1) to quantify seasonal groundwater contribution to total stream discharge and (2) further our understanding of sub-arctic carbon sources and pathways within a sub-arctic discontinuous permafrost river catchment. Twenty-two samples were taken from the North Klond...
