Icing (aufeis) and seasonal water chemistry in lakes and streams on the subarctic Taiga Shield near Yellowknife, NT.

This dataset represents a compilation of water chemistry parameters (dissolved organic carbon, nutrients, trace metals, major cations, water isotopes, carbon isotopes), dissolved organic matter composition (via UV-Vis spectroscopy and FT-ICR-MS- analysis) parameters at eight lakes in the subarctic Taiga Shield near Yellowknife, NT, which feed icings (aufeis) formation in the winter in downstream channels; icings have the potential to archive and modify the composition of flowing water in the winter. The dataset also includes the results of an incubation experiment at one site, and lake level data at two sites. Data show differences in water chemistry, carbon composition, and biolability of carbon across icings, winter, spring and summer surface waters (i.e. lake and stream water); data also shows seasonal variation in lake levels in lakes which feed icing formation. Collection dates and site information included in dataset.
