A 2026 study by F Dauti, Y Ley Cooper, T Munday, A Viezzoli, and G Fiandaca connects numerical modeling with field evidence for induced polarization effects in fixed-wing airborne electromagnetic surveys. The dataset likely contains synthetic model results and field-scale observations from over 470,000 line-km of TEMPEST™ data within the AusAEM dataset. It was published by Geoscience Australia to address a gap in understanding IP effects in fixed-wing AEM systems.
Use Cases
- Modeling induced polarization sensitivity based on variable resistivity and chargeability parameters described in the study.
- Interpreting negative secondary field responses in AEM data based on the connection to low shallow conductance areas.
- Comparing fixed-wing and helicopter-borne AEM system performance for IP detection as discussed in the description.
- Assessing the role of near-surface electrical conductance in obscuring or revealing polarization currents in survey data.
Strengths
- Connects synthetic modeling with field evidence from over 470,000 line-km of TEMPEST™ survey data.
- Examines nine geometric parameters (pitch, roll, yaw, offsets) affecting fixed-wing AEM data interpretation.
- Published by Geoscience Australia, an authoritative national geoscience organization.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
