Geophysics Group

AGM 2022

Our Annual general meeting, planned for Thursday 9 March at 10am, has unfortunately had to be cancelled due to low attendance. Group members will be informed of next steps when they happen.


Geophysics Group (GeoSIG) represents the interests of archaeological geophysicists to CIfA and in the Institute's activities. GeoSIG role is to act as a focus for CIfA members interested in geophysics, produce documents and guidelines relating to geophysical work and to promote geophysical work constructively within the structure of archaeology.

GeoSIG is working closely with ISAP, NSGG, and EuroGPR to ensure that we keep up to date with developments in the wider geophysical community. The committee also has close links with the Near Surface committee of EAGE.
