Abstract

In the present study, GPR surveys are used to interpret the evolution of representative trough-blowouts within Padre Island National Seashore, based on the assumption that the bedding structures formed during blowout evolution cause reflections that can be recognized in radar transects (Everett 2013). These features do not definitively categorize environments however it is possible to assign specific stratigraphic features with phases of blowout evolution. In order to understand the surficial expression and extent associated with each phase aerial photographs from 1969 to 2010 and LiDAR data from 2005 and 2011 were used to help interpret the structures observed in the GPR surveys and create a three dimensional understanding of blowouts within Padre Island National Seashore. © 2013 SEG.
