USArray Data Processing Short Course for the Next
Generation of Seismologists VI
Goals:
• Provide you with exposure to and training in the foundations of
robust methods in seismic data processing,
• Address and share opportunities and challenges in USArray data
processing,
• Empower and inspire you to become future leaders in developing
more effective ways to handle data from large seismic arrays, such
as USArray.

Background:
• TA Working Group came up with the idea.
• TAWG members Gary Pavlis and Suzan van der Lee applied to
NSF to fund a short course for advanced graduate students.
• First short course held in 2009 in MacLab in Northwestern
University Library, with enthusiastic support from Bob Woodward.
• Last year (2013) a more introductory short course was added
• You are the critical part of the sixth short course.

Final student projects:
• Process a USArray data set to measure a geophysical quantity.
• Hypocenters, Receiver Functions, Teleseismic Arrival Times,
Shear Wave Splitting, for example.
• Push boundaries of processing techniques.
• Feel empowered and inspired
to improve techniques.
• Share.

• work locally on /Users/usarray/ … Desktop/USArray_Course
• remember iMac number and work at same one each day in order to
have your previous day’s work – or/and save on USB each day!
• raw data (for down-copying only) and e-handouts are on the
shared disk /Volumes/USArray or through shared-drive icon on
Desktop
• never change anything on /Volumes/USArray (unless specifically
asked by an instructor)
