Regions: Sahtu Settlement Area

Tags: physical sciences, geology, aeromagnetic survey

Principal Investigator: Tod, Joan (1)
Licence Number: 13003
Organization: NRCan, Geological Survey of Canada
Licenced Year(s): 1998
Issued: Sep 01, 1998
Project Team: Contractor: SIAL Geosciences Inc.

Objective(s): The purpose of the survey is to improve public knowledge and understanding of the geology of this area, as no publicly available magnetic coverage exists. Survey lines will be flown at a spacing of 800 m and a 200m mean terrain clearance. The purpose of the survey will be to record the variation in the earth's magnetic field caused by magnetic minerals contained in the rocks of the earth's crust. The patterns obtained are indicative of the subsurface geological structure and are used as an important element of geological mapping and resource exploration. This program of Regional Aeromagnetic Mapping has been carried by the Geological Survey of Canada since the late 1940's. The GSC is responsible for preparation of the survey contract, monitoring of the survey operation and public distribution of the data through the Geophysical Data Centre.

This is entirely an airborne survey, so there will be no land access. No new technology will be implemented for this survey. The aircraft will be equipped with state of the art magnetometer and navigation systems including Global Positioning System (GPS).
