ENAM seismic refraction processing workshop

In the week of May 18-22, 2015, we will host a 5-day training workshop at the University of Texas in Austin for students and early-career scientists who want to gain experience with the analysis of active-source seismic refraction data. Participants in this workshop will learn how to identify seismic phases, pick arrival times, and invert for crustal seismic velocity structure along geophysical transects. Hands-on learning will be accompanied by lectures explaining the basic assumptions and geophysical theory behind the seismic refraction methods.

In the workshop we will use ocean-bottom seismic refraction data, as well as onshore-offshore seismic refraction data, that were acquired in September and October 2014, during the ENAM Community Seismic Experiment offshore North Carolina. Five geophysical transects of this recent project characterize the rifted margin of the eastern United States. The wide-angle seismic refractions from these data will show the variation in deep structure from the continental crust onshore to ocean crust beneath the abyssal plain.

Interested participants should send a statement summarizing why they wish to attend the workshop, together with a short CV, to gail@ig.utexas.edu. Limited travel funds are available for participants.

Application deadline is March 15, 2015.
