1. "Improving Definition: GPR Investigations at Westminster Abbey" in Daniels, J & Chen, C (eds) Proceedings of the 11th International Conference on Ground Penetrating Radar, June 19-22, 2006, Columbus, Ohio, USA.

Papers 1-2 are in the field of the Cultural Heritage. Paper #1 paper illustrates the importance of total area coverage and dense data collection as well as the target definition achievable with a very high (4 GHz) frequency antenna.


2. "The Shrine of Edward the Confessor: a study in Multi-Frequency GPR Investigation" in Near Surface Geophysics Vol 10, No 1, February 2012, pp. 65-75.

Paper #2 also illustrates the power of using total area coverage and dense data sets as well as discussing the factors affecting selection of antenna frequency. Papers 3-4 deal with Environmental Investigations.


3. "The Investigation of a Peat Moss using Ground Probing Radar" in the Proceedings of the Workshop "Remote Sensing by Low-Frequency Radars", held jointly by the Consortium of Research on Advanced Remote Sensingy Systems and the European Association of Remote Sensing Laboratories, Naples, Italy, September 2001.

Paper #3 deals with the practicalities of investigating a fully waterlogged environment and of obtaining extensive information over a wide area using a low frequency GPR.


4. Utsi, E (2007) "Wetlands viewed through the antennas of a Ground Penetrating Radar" in Barber, J, Clarke, C, Cressey, M, Crone, A, Hale, A, Henderson, J, Housley, R, Sands, R & Sheridan, A (eds) 'Archaeology from the Wetlands: Recent Perspectives', Proceedings of the 11th WARP Conference, Edinburgh, 2005, pp 213-218.

Paper #4 deals with a wide range of issues raised by operating with a GPR in a wetland environment. It builds also on earlier work carried out at North Ballachulish, Highland, Scotland which remains one of the few successful wetland archaeological investigations.


5. "Detection of Subsurface Reflective Cracking using GPR" in Forde, M (ed) Proceedings of Structural Faults & Repair Conference, Edinburgh, June, 2008. Authors are Utsi, E., Birtwisle, A., & Cook, J.

Papers 5-6 deal with Structural Investigations. Paper #5 illustrates the use of specialised GPR equipment for the detection of subsurface cracking which has not yet permeated to the ground surface, in this case of a military airport runway. The investigation allows structural engineers to determine the timing and degree of runway repairs, minimising the disruption caused to the operation of the airport.


6. With Utsi, V. "Measurement of Reinforcement Bar Depths and Diameters in Concrete" in Slob, E., Yarovoy, A., & Rhebergen, J. (eds) Proceedings of the Tenth International Conference on GPR, Delft, Netherlands, 2004, pp. 659-662.

Paper #6 illustrates the use of a high frequency GPR to determine not only the position and orientation of reinforcement bars in concrete but also trials a form of measuring their relative size.
