Canadian plans for participation in GSETT 3
The Geological Survey of Canada (GSC) is making preparations for Canadian participation in GSETT 3 but will be unable to make a formal commitment until the necessary resources have been secured. As Canada is expected to provide at least four alpha stations, and a significant number of beta stations,...

The Geological Survey of Canada (GSC) is making preparations for Canadian participation in GSETT 3 but will be unable to make a formal commitment until the necessary resources have been secured. As Canada is expected to provide at least four alpha stations, and a significant number of beta stations, the financial resources that will be needed are substantial, even though in many respccts the GSC is, with the recent modernization of the Yellowknife array and the ongoing installation of the Canadian National Seismograph Network (CNSN), well positioned to make a significant contribution to GSETT 3.
