Objective(s): The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions.
Project Description: The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions. Soil gas sample tubes will be sampled on a seasonal basis for gas concentration (CH4, N2O, CO2) and isotope ratios. The response of ecosystems (e.g. soil moisture, vegetation, chemistry) to changing conditions (e.g. precipitation, temperature, permafrost) will be monitored. Flux chambers will be deployed to determine the net CH4, N2O and CO2 fluxes. A web site will be maintained and a plain language summary provided. Regional GNWT employees will be involved in fieldwork (including Steve Gooderham, Paul Rivard, Mike Gravel, Nancy Stevens-Whiteman). NWT college or university students will be hired and trained to assist in the fieldwork. Fieldwork will be conducted from June 01 to August 31, 2008 near Norman Wells, Inuvik and Fort Simpson.
