IRIS USArray Advanced Short Course, 2017
Indiana University, Bloomington, IN,

Instructors: Heather DeShon (Southern Methodist University), Marianne Karplus (University of Texas - El Paso), Charles (Chuck) Langston (The University of Memphis), Fan-Chi Lin (University of Utah), Robert Mellors (Lawrence Livermore National Laboratory), Gary Pavlis (Indiana University), Brian Stump (Southern Methodist University), Justin Sweet (IRIS), Danielle Sumy (IRIS)

The primary goal of this short course is to provide training in the foundations of seismic data processing for the next generation of geoscientists. Our aim is to inspire the participants to become leaders in developing more effective ways to handle data from large seismic datasets. This year's course will focus on power methods for fetching, processing, analyzing, and visualizing data locally, specifically with the Oklahoma Wavefields data. To learn more about the Oklahoma Wavefields experiment, including how to access the dataset, head on over to Attendees are expected to already have some experience with seismological data and scientific computing. 

Participants will be selected into each short course by the program's steering committee based on the information provided in their applications. Travel, lodging, and most meal costs for selected applicants will be covered by financial support from NSF through the "Seismological Facilities for the Advancement of Geoscience and EarthScope" award to IRIS. Please note: Selection and financial support will be focused on applicants who have not attended previous USArray short courses and are based at institutions within the U.S. International participants may also apply, but are responsible for their expenses and logistics if coming from outside the U.S. Regarding more details on financial support, please visit the 'Location' tab.

Please note: International participants are welcome to apply, but are responsible for their expenses and logistics if traveling from outside of the U.S. Attendees from previous USArray Short Courses should not apply to this course. For more information, contact Danielle Sumy.

The course will be held on the campus of Indiana University, located ~1 hour from Indianapolis.

Selection for the short course includes support for travel ($650 towards airfare, taxi, public transit, etc.) between your origin and Indianapolis (and shuttle bus service to Bloomington). Meals during the week will be reimbursed, with original itemized receipt. This does not include meals which are already covered by IRIS (such as group dinners and lunches with IU voucher). Meals will NOT be covered on travel days. Lodging (double occupancy) will be provided at IU for 5 nights. A sixth night may be supported depending on individual circumstances/flight schedules.
