· Update section on Ground Penetrating Radar to include multichannel methods
· New section on surface wave seismics (a method that has been languishing in the background for many years but is now becoming very popular)
· New section on borehole geophysics (crosshole/downhole seismics, crosshole res, crosshole GPR. Formerly restricted to ‘large-scale’ operations but now becoming more routinely applicable)
· Section on towed array systems (becoming increasingly popular for large accessible areas)
· Major update of section on use of GPS.
“Overall, Field Geophysicsone of several published by Wiley-Blackwell in their Geological Field Guide Seriesis a good practical introductory reference book for a geophysical technician beginning their career or a quick refresher for someone using an instrument they haven’t picked up for many years.” (Environmental & Engineering Geoscience, 2 May 2013)
