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. <o:p></o:p></p><p style="font-weight: normal; margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; text-align: justify; ">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. <o:p></o:p></p><p style="font-weight: normal; margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; text-align: justify; "><img width="232" height="200" id="_x0000_i1047" src="http://geoprisms.org/wpdemo/wp-content/uploads/2015/01/ENAM-workshop-2015-fig1.png"><img width="341" height="200" id="_x0000_i1048" src="http://geoprisms.org/wpdemo/wp-content/uploads/2015/01/ENAM-workshop-2015-fig2.png"><o:p></o:p></p><p style="font-weight: normal; margin-right: 0in; margin-left: 0in; font-size: 12pt; font-family: 'Times New Roman', serif; text-align: justify; "><em>left.
