Pilgrim Springs - Alaska Magnetotelluric (MT) Survey 2012 (Final Report)

Fugro Gravity and Magnetics Services (Houston) with Fugro Electro Magnetics Italy Srl carried out a full tensor, broadband magnetotelluric survey of 59 soundings under contract from University of Alaska. Two MT field teams deployed up to 3 MT systems each (ADU-07e Metronix receivers and sensors) for overnight recording, thus producing up to 6 MT soundings per day. Fieldwork was completed between August 13 and August 28, 2012. Inversion for 3D resistivity structure was performed using the Fugro RLM-3D MT code. Full tensor complex impedances were inverted in the frequency range from 0.032 Hz to 5.62 kHz, using 4 frequencies per decade, on a 384 core cluster. Both unconstrained (blind) and constrained inversions were carried out. For the constrained inversion, the starting and a priori model in 3D inversions included shallow structure from resistivity-depth maps obtained from the Resolve airborne EM survey, conducted by Fugro Airborne Surveys Corp., Mississauga, Canada. Report 78 pages, Append. A-D. 50 Figures, 8 Tables.
