This week-long course will provide hands-on experience with the state-of-the-art magnetotelluric (MT) instruments managed by the PASSCAL Instrument Center (PIC) and the evolving landscape of software tools for developing research products with MT datasets. The short course will combine field demonstrations, lectures, guided exercises, and group discussion. Instruction and training will be provided by PIC's technical staff and experts from the MT science community. We welcome participants from a variety of backgrounds and career stages (graduate student and beyond), and are especially keen to engage potential future users of PASSCAL facility portable MT instrument pool. Course enrollment will be capped at around 15 attendees.
Funding to attend is available for individuals currently based at a U.S. academic institutions and for U.S. citizens doing research work abroad, and will support costs related to domestic travel, room, and board. Applications to participate can be submitted by completing the form on the "Apply Online" tab above, and should be submitted no later than Wednesday, September 7, 2022. Selections will be finalized by September 16, and participants should plan to arrive on Sunday, October 16 by late afternoon and depart after midday on Friday, October 21.
Course organizers include Anna Kelbert, Jared Peacock, and Paul Bedrosian (USGS), Esteban Bowles-Martinez (Oregon State University), Lindsey Heagy (Univ. British Columbia), Seogi Kang (Stanford), and Karl Kappler (Imdex Ltd).
Please direct any questions or concerns to Justin Sweet.
The course will be held at the New Mexico Institute for Mining and Technology (NMT), located in the specatcular geology of the south-central Rio Grande Rift in Socorro, New Mexico, ~1 hour south of Albuquerque. For over two decades, NMT has been home to the PASSCAL Instrument Center, an internationally recognized facility for supporting portable geophysical instrumentation used by Earth scientists.
Selection for the short course includes support for travel (plane, rail, car, taxi, public transit, etc.) between your origin and Albuquerque, with course-organized rides to/from Socorro. Meals during the week will be provided at no cost or will be reimbursed with original itemized receipt. Lodging (single-occupancy) will be provided in Socorro for 5 nights.
All short course participants will be asked to follow our COVID policy, which includes providing proof of vaccination and encourages mask wearing.
