Electrical resistivity tomography and electromagnetic induction and measurements at Bogg Creek, Sahtu Settlement Area, Northwest Territories. Sahtu Region, Canada

Northern cold regions are especially susceptible to climatic variations, and as a result of global climate change, it is important to understand the permafrost distribution using more efficient methods. Surficial alterations, both natural and anthropogenic, can be indicators of permafrost degradation. The objectives of this research are to execute the geophysical surveys using electrical resistivity tomography (ERT) and electromagnetic induction (EMI) to detect changes in permafrost table depth and to assess the efficiency of the EMI method versus ERT method within the Sahtu Region in the Northwest Territories. This data set will also support the objectives of projects titled Transformative sensor Technologies and Smart Watersheds (TTWS) and the Northern Water Futures (NWF). These projects are Pillar 3 projects under the Global Water Futures Program funded by Canada First Research Excellence Fund.
