Geophysical survey has become a standard archaeological prospecting technique to ascertain the nature of the ground deposits that lie buried beneath the surface. The use of sonic pulsing underlies a suite of different techniques used to gain insight.
Marine Geophysical survey has seen significant advances in recent years with the application of digital technologies. There are four principal marine survey techniques: multi-beam bathymetry provides superior underwater contour data; side-scan sonar maps the seabed/riverbed surface and is ideal for detecting anomalies and structures that are exposed on the surface; magnetometry can identify ferrous metal objects that lie either on the seabed or are buried within the sedminentary layers; and seismic survey can trace the survival of signiificant buried structures and features, such as shipwrecks and ancient shorelines and palaeo-channels.
ADCO is recognized by the Department of Arts, Heritage and the Gaeltacht as being capable in providing a robust archaeological interpretation of marine geophysical survey data. We advise on the most appropriate equipment for particular jobs, and we offer an independant assessment of the data acquired.
