Hydrogeology, isotope, and geochemical data from Bogg Creek, Sahtu Settlement Area, Northwest Territories

This project aims to characterize and map groundwater flow within a discontinuous permafrost region at Bogg Creek Watershed, near Norman Wells, Northwest Territories, using indirect techniques, such as tracers. Hydrocarbon extraction and climate change both pose potential threats to groundwater and surface water resources in northern, permafrost regions, prompting the need for baseline monitoring of water resources prior to disturbance. Collecting baseline data can be expensive, difficult and even impractical given the unique environment and extreme climate, and few standard protocols exist. This data forms the basis of an exploration into the viability of using indirect methods of characterizing groundwater flow in this region. This is in order to form a conceptual model that can be used to select further monitoring sites. This is via use of several environmental tracers, including temperature, isotopes, and geochemistry.

This data set is collected for the project titled “Transformative sensor Technologies and Smart Watershed (TTWS): Work Package 1". TTWS a Pillar 3 project under the Global Water Futures Program funded by Canada First Research Excellence Fund.

Digital Elevation Model data and climate data for this project were downloaded from publicly available online sources from Government of Canada Open Data Catalogue GEOGRATIS (http://geogratis.cgdi.gc.ca/) and Environment Canada and Climate Change (http://climate.weather.gc.ca/) websites respectively; data will also be collected during fieldwork. Field techniques included collection of various tracers such as isotopes, geochemistry, and temperature. Data includes surface water and shallow groundwater quality and chemistry, 18O, 2H, 3H, 87Sr, and 13C isotopes, as well as sampling locations, measurements of active layer thickness, hydraulic conductivity and geology. Data is in spreadsheet and shapefiles/geospatial data formats.
