Magnetotelluric survey of Kapunda, South Australia, 2019–2020

Brief description

This record was harvested by RDA at 2026-09-03T11:58:32.790222+10:00 from NCI's Data Catalogue where it was last modified at 2026-02-20.

Full description

Broadband magnetotelluric (MT) data were acquired across the Kapunda region of South Australia in 2019 and 2020 to support investigation of subsurface electrical conductivity structure associated with the Kapunda In-Situ Copper and Gold Field Recovery Trial. The survey comprises a total of 83 broadband MT sites, including 58 sites collected during the 2019 field campaign and an additional 25 sites collected during the 2020 campaign. Sites were distributed across the Kapunda project area to provide regional-scale coverage of the target zone. Data acquisition was conducted in two phases corresponding to the 2019 and 2020 field campaigns. Each deployment included parallel instrument tests undertaken during site occupation. The 2019 campaign utilised Geoscience Australia broadband MT systems, while the 2020 campaign employed a combination of Geoscience Australia and University of Adelaide broadband MT systems. This collection provides a broadband MT dataset suitable for analysis of crustal electrical resistivity structure and supports integrated geophysical investigation of the Kapunda region.

Lineage

Data in this collection were acquired during a broadband magnetotelluric (MT) survey conducted across the Kapunda region of South Australia in 2019 and 2020. The survey formed part of the Cooperative Research Centres Projects (CRC-P) program project entitled "Kapunda In-Situ Copper and Gold Field Recovery Trial", for which Environmental Copper Recovery SA Pty Ltd was the grant recipient. Field acquisition was conducted in two phases. The 2019 campaign comprised 58 broadband MT sites and the 2020 campaign comprised an additional 25 sites. Parallel instrument tests were undertaken during site occupation to assess consistency between acquisition systems. Field acquisition employed ultra-wideband magnetotelluric (MT) instrumentation provided by Geoscience Australia and the University of Adelaide, including Phoenix MTU-8A systems operated by Geoscience Australia and Phoenix MTU-5C systems hosted and operated by the University of Adelaide. University of Adelaide instrumentation was accessed through the AuScope - ANSIR Research Facility for Earth Sounding. The University of Adelaide instrument pool was acquired through AuScope funding provided under the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS). Continued availability of the ANSIR instrumentation pool is supported through ongoing NCRIS investment via AuScope, including maintenance, calibration, refurbishment, and operational management activities. AuScope is supported by the Australian Government’s National Collaborative Research Infrastructure Strategy (NCRIS). This collection documents the acquisition history, instrumentation, funding sources, and operational context associated with the Kapunda MT survey and provides provenance information for all derived datasets.
