Variability in peat plateau energy balance and water chemistry along a warming gradient
Principal Investigator: English, Michael C
Licensed Year(s): 2013
Summary: This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...


Degradation of dissolved organic carbon in Mackenzie Delta lakes and river channels
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2013 2012
Summary: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...


Geological carbon in the Mackenzie River Basin: Sources and sinks of atmospheric carbon dioxide
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2017 2013 2011 2010 2009
Summary: The overall aim of this project is to assess the carbon balance of the Mackenzie River Basin and to place constraints on the role of climatic and physical erosion processes in driving carbon dioxide source and sinks to the atmosphere and oceans. More specifically, the researchers aim to quantify the amount of chemical weathering that takes place in the Mackenzie River Basin, to quantify how much w...
