Field opportunity for EarthScope seismic refraction project in Georgia

In July-August 2015, a team of scientists will collect seismic refraction data in Georgia as a part of an NSF-Earthscope project to study the relationship between extension, magmatism and an ancient suture beneath the South Georgia Basin. We think that this project will yield exciting new information on the geological history of the southeastern US, which was at the center of some of the biggest tectonic events to shape North America.

The field work: We are looking for volunteers to help us collect these data.  This is a great opportunity to gain hands-on experience in acquiring seismic refraction data and learn about this technique and the tectonic history of the southeastern US. We will acquire seismic refraction data along of two profiles in eastern Georgia in late summer 2015. Geophones spaced at ~100-250 m will record a series of 200-2000 lb explosive shots (the seismic sources). Volunteers would be involved in deploying and recovering geophones, and will have the chance to see some of the shots.

Timing: Our planned dates for the program are July 29 – Aug 15. Ideally, we are looking for people who can participate for the entire program. However, even if you cannot participate for the full time, we may still be able to use your help!

Travel costs and living expenses: We will cover all of your expenses during the field work and your travel to/from the field area. We also plan to give a couple of lectures during the field program on active source seismology and tectonics of this region.
