Objective(s): To continue characterizing three of the larger gas seeps observed and reported by the National Energy Board, GSC and Inuvialuit

Project Description: Field research for 2011 will concentrate on two tasks:
1) Continued characterization of three of the larger gas seeps observed and reported by the National Energy Board, GSC and Inuvialuit.
2) Data logger (water temperature, level, conductivity and dissolved oxygen) retrieval and redeployment.

The researcher will characterize water geochemistry, through collection of samples for subsequent laboratory analysis for comparison with previous year’s results. Measurement of gas discharge will be completed using portable/hand-held flow measurement devices for comparison with previous results to evaluate possible changes in gas flow rates. Possible methane anomalies will be identified through direct temperature measurement and/or remote sensing techniques. Local/regional geology will be assessed to identify the geologic origins of these active gas flows. Non-invasive geotechnical methods will be conducted to determine the base of permafrost (potential activity if funding and resources permit).

The researcher communicates with the communities near the area of study through this application process, including the report on licensed research. During these communications the researchers have offered to provide any additional information required in any practical way. When there are published results they will be sent to these the communities and regional governing organizations. The geocomplexity program has been described on posters designed for the public (northerners in particular) and displayed at Inuvik Research Centre. Any paper or digital products produced from this research will be offered to the local libraries and community associations for inclusion in their archives.

The fieldwork for this study will be conducted from July 1, 2011 to August 19, 2011.
