Objective(s): To investigate the structure and composition of the Earth's crust and upper martte to depths of greater than 200 km along Echo Bay's winter road from east of Yellowknife to the Lupin Mine at Contwoyto Lake, possibly extending to the Jasper property. The work should define the base of the Slave craton, and is an important component of the national LITHOPROBE Program, which is aimed at understanding the tectonic evolution of the North American continent.
Project Description: At approximately forty (40) locations along the 600-km-long winter road, sensors will be lowered through small holes drilled through the lake ice onto the lake bottom. These sensors will measure time variations of the Earth's natural electric field, and these variations will be recorded by devices on the lake shores. The recordings at each locations will take 1-3 weeks, after which all equipment will be removed. The measurements are passive and totally nondestructive and no disruption of traffic will occur.
