Objectif(s): To investigate the structure and composition of the Earth's crust and mantle to depths of 0-300 m, and to investigate new methods to characterize diamond reservoirs in order to make exploration more efficient and low impact.

Description du projet: This ongoing study will investigate the structure and composition of the Earth's crust and mantle to depths of 0-300 m, and investigate new methods to characterize diamond reservoirs in order to make exploration more efficient and low impact. Teleseismic observatories are sited in remote locations in either linear or rectangular arrays where they record distant earthquakes for several years. Magnetotelluric stations are similar, but need record for only days or weeks. Each station consists of a sensor buried <1 m in gravel, a satellite dish, solar panels and battery/electronics boxes. Seismic waves travel from earthquakes occurring around the globe to be recorded by the sensor and transmitted to Ottawa using the satellite telemetry link (same as TV signals) where they can be publically accessed via the internet. The results will be shared through presentations at the Yellowknife Geoscience Forum. The results will be published in scientific journals. The NT Geoscience Office will take the lead in communicating these results with related geology studies. The fieldwork for this study will be conducted from January 1, 2011 to December 31, 2011.
