Geophysics Special Interest Group (GeoSIG)

GeoSIG logo


Members of the Chartered Institute for Archaeologists (CIfA) and the wider archaeological geophysical community have come together to form the CIfA Geophysics Special Interest Group (GeoSIG). Open to both CIfA members for free and to non-CIfA members for a small fee. The GeoSIG represents the interests of archaeological geophysicists to CIfA council and in the Institute's activities.

The role of GeoSIG is to

  • act as a focus for CIfA members interested in geophysics
  • produce documents and guidelines relating to geophysical work
  • promote geophysical work constructively within the structure of archaeology

The group is currently examining a number of specific issues

  • the practical implementation of guidelines such as the Geophysical Survey in Archaeological Field Evaluation (English Heritage, 2008)
  • archiving of geophysical data
  • training and CPD for practitioners in archaeological geophysics
  • training and CPD for users of archaeological geophysics

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.

Join the Group

Membership is free to CIfA members (£10 for non-members). To join, please contact the CIfA office at

Tel: 0118 378 6446



The GeoSIG committee comprises of:

Jimmy Adcock (Chair)
David Sabin (Secretary)
Andrew Hutt (Treasurer)
Martin Roseveare (OCM, EuroGPR liaison)
Lucy Learmonth (OCM)
Michael Puntorno (OCM)

Advisory/liaison members:
Alastair Ruffell - Forensic Archaeology group liaison
Paul Linford - HE & ISAP liaison
Anne Roseveare - liaison with BSSS
Matt Guy - NSGG liaison
Will Davies - CADW Liaison

There are representatives from ISAP, NSGG, EuroGPR, EAGE and Historic England, and plans to include representatives from ALGAO, Cadw, Historic Scotland and NIEA.

Specialist competence matrix

We have recently introduced specialist competence matrices, which have been compiled by our CIfA special interest groups and are tailored to their specific areas. These are to assist applicants and the Validation committee to see where you demonstrate the grade applied for.

CIfA GeoSIG/ADS workshop

At the end of last year GeoSIG held a workshop in conjunction with ADS on the archiving of geophysical data. As part of that event the participants were split into small groups and each took it in turns to write down their responses to the following 5 "seed" questions from both ADS and GeoSIG:

  1. As a data creator, what do I want a digital archive to do for me?
  2. As a data user, what do I want a digital archive to do for me?
  3. Are there any useful tools or guidance on archiving available? If not, what would you like to see created?
  4. The main difficulties I face when it comes to archiving are…
  5. Who drives the archiving of your data (i.e. you / management / outside influences) and how much of that data do you archive rather than back-up?

A spreadsheet of the unedited responses was compiled - these have been written up directly from the group notes made on the day. None of the groups saw what the others had responded with, so there may be some repetition amongst the answers.

If you were not able to attend and would like to add your own responses, or add comments to those answers already received, please feel free to fill in the relevant cells and return the document to the Chair jimmyadcock.geosig [at] (Jimmy Adcock)

There were a number of actions to come out of the day which we are now working on enacting. The most immediate task will be a poll to determine the spread of survey sizes undertaken in the UK over the last couple of years. This information will be key to helping ADS evolve the submission process for geophysical
datasets, so I would encourage you to participate when we launch the survey.

Past events

Archiving Workshop
CIfA GeoSIG & ADS jointly hosted an archiving workshop on 27 November 2015 focused specifically on data archiving for geophysics using the ADS services.

Louisa Matthews (ADS Collections Development Manager) and Ray Moore (ADS-easy Manager and Lead Digital Archivist) gave presentations focused on the ADS system whilst GeoSIG committee members also attended to contribute to round-table discussions.

A one day seminar on Geophysics was hosted with ALGAO on November 2010. Some of the presentations from the day can be downloaded below
