A multi‐institutional research initiative, POLARIS, is providing scientists with unprecedented opportunities to map Earth structure and assess earthquake hazards across Canada. By completion of the initiative's installation phase in August 2005, deployments of POLARIS (Portable Observatories for Lithospheric Analysis and Research Investigating Seismicity) instruments will include 100 telemetered broadband seismograph systems, 10 with continuous‐recording magnetotelluric (MT) devices (devices that record natural variations in the geomagnetic field). Data from these observatories are transmitted by satellite (with a latency of 5 s) to data acquisition hubs in London (Canada) and Ottawa, where they are made available in near real‐time by an automatic data‐request manager (AutoDRM). Conceived in 2000 by an interdisciplinary group of 10 geoscientists, the 4‐year, C$11 million infrastructure project is fostering strong partnerships between academia, government laboratories, and the private sector.
