Objectif(s): To continue characterization of three of the larger gas seeps observed and reported by the National Energy Board, GSC and Inuvialuit; and the Identification of additional seeps in the region through aerial surveys, regional studies of geology and gas release on Richards Island and Tuktoyaktuk Peninsula.

Description du projet: Field research for 2010 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) Identification of additional seeps in the region through aerial surveys, regional studies of geology and gas release on Richards Island and Tuktoyaktuk Peninsula. The researcher will characterize water geochemistry, through collection of samples for subsequent laboratory analysis for comparison with previous results. Measurements 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). An Aurora Research Institute technician will be involved in the field work and to seek the assistance of local HTCs to assist with the identification of gas seeps. The researcher expects to give a community talk on the research during the summer of 2010 if arrangements can be made with ARI. The researcher will communicate with the communities near the area of study through this application process, including the report on licensed research. When there are published results, they will be sent to 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 June 10, 2010 to October 7, 2010.
