Buried valley imaging using AEM surveys, electrical resistivity and 3-C seismic reflection

The Geological Survey of Canada has conducted an airborne electromagnetic (AEM) survey (AeroTEM III) and follow up ground based, multi-electrode electrical resistivity and high-resolution seismic reflection surveys over the southern portion of the Spiritwood valley in southwestern
Manitoba. The combined data provide exceptional 3-D coverage which have highlighted key hydrological features such as a complex system of buried channel aquifers and potential sub-surface hydraulic pathways or connections. Such information is critical to groundwater prospecting and to the accurate
assessment of recharge and discharge potentials associated with buried valley aquifers.
