Seeing Beneath the Surface: Using GPR in Geomorphology Seminar

15 October 2014
Shackleton Building 44, Lecture Theatre B

Event details


Ground Penetrating Radar (GPR) has many applications in geomorphology and Quaternary Geology. It is a variety of remote sensing using electromagnetic radiation to image the shallow subsurface. The equipment is portable and relatively easy to operate, although data processing and interpretation can be more time consuming and requires greater expertise. This lecture uses a number of themes to illustrate the use of GPR starting with ground truth to confirm that GPR reflections do match subsurface stratigraphy; testing depth of penetration and the range/resolution trade-off; stratigraphic studies identifying relative chronology from superposition and cross-cutting relationships and selecting sample locations. Case studies include visualisation of river deposits, sand dunes, coastal sediments and peat in cross-section and 3-D with examples from around the world including Antarctica, Australia, New Zealand, Namibia, North America and Yorkshire.


Introduction to GPR

15:30 Lecture Theatre B – pre-seminar introduction immediately prior to professor Bristow’s seminar.

Prior to Professor Bristow's talk, Dr Arjan Reesink, Research Fellow in Physical Geography University of Southampton, will present a 15 minute Introduction to GPR. This short introduction will cover the fundamentals of what GPR is, what it shows, and what to expect when using it. This talk is followed by an opportunity to get acquainted with Southampton’s GPR system, and to interact with academic and technical staff members involved with the use and maintenance of the GPR. A ‘must see’ if you are interested in learning about GPR.
