05 Publication archive

Technical papers, presentations & posters.

Publications from SolPEG’s technical work.

A selection of our own analyses, conference contributions and technical publications. The archive documents the development of technical questions and methods over many years.

Technical knowledge in its original form.

The publications are grouped by topic and ordered chronologically within each group. Older publications remain intentionally visible: they document our technical track record and the development of our methodology.
