Objectif(s): Survey the Dempster and ITH highways to measure methane emissions from the highway and correlate those emissions to landscape features (wetlands and small lakes) that are in close proximity to the highway.

Description du projet: This licence has been issued for the scientific research application No. 6128. Survey the Dempster and ITH highways to measure methane emissions from the highway and correlate those emissions to landscape features (wetlands and small lakes) that are in close proximity to the highway. - Outfit a survey vehicle with a methane sensor and calibrate. Drive the Dempster-ITH highways from the Yukon border to Tuk and perform a methane measurement survey. This survey should happen 3 times per year from late Spring to late Fall. When methane spikes occur, stop and survey the area with a drone-based methane sensor to pinpoint the source and measurement at source. Send the methane data to ARI and FluxLab (Nova Scotia) for analysis along with any ancillary data such as close proximity eddy co-variance tower measurements. - Correlate the analysed data with landscape features in the area. The landscape features (wetlands and small lakes) will be derived from satellite data analysis. Typically, monthly maps of these features will be produced if cloud free imagery is available for that month. Otherwise, a composite map that incorporates satellite data over 2 or more months will be produced. - Assign methane factors to the landscape features based on several characteristics such as size, shape, water depth, ice cover, time of year, precipitation, etc. - Inventory the methane emissions over the study area based on derived methane factors - Several NWT stakeholders will be monitoring the project in addition to ARI directly participating in the project with IRC, so communications about project progress and results will be directly shared with them. - NWT Centre for Geomatics will be monitoring the project to evaluate the use of AI in developing landscape feature maps from satellite data. - GNWT ECC will be monitoring the project to evaluate the potential for this survey and other research projects to contribute to the NWT landscape emissions inventory - IRC staff or beneficiaries will participate in the project for mentoring/training during the vehicle and drone-based surveys to evaluate the potential to conduct the surveys themselves in the future - The project will be communicated at the upcoming Landscape Carbon Workshop in Yellowknife led by GNWT ECC during February 2025 - The project will be communicated at the upcoming Arctic Development Expo in Inuvik during June 2025 - The project is being communicated to the NWT Association of Communities. The fieldwork for this study will be conducted from: March 1 - December 31, 2025
