NSF-SUPPORTED NATIONAL FACILITIES FOR TERRESTRIAL CONTROLLED SOURCE

The National Geoelectromagnetic Facility - The National Science Foundation has awarded funding to develop and build ultra-wide band (dc, micro-Hz-to-hundreds of kHz) EM receivers and supporting equipment including transmitters, for MT, AMT, CSAMT, TDEM, IP, dc resistivity methods. These new instruments (expected to be commissioned in 2011) will be available to US investigators and their non-US collaborators. Depot, support and maintenance of these instruments will be carried out by Oregon State University, which is also carrying out these support functions for the two existing instrument pools detailed immediately below.
