Magnetotelluric survey of the Curnamona Province, New South Wales, 2017 (Level-2 EDI products)

Brief description

This record was harvested by RDA at 2026-09-03T11:58:31.048857+10:00 from NCI's Data Catalogue where it was last modified at 2026-04-10.

Full description

This dataset comprises Level 2 magnetotelluric (MT) data products derived from raw broadband time-series data acquired during the New South Wales component of the 2017 Curnamona Province MT survey. The dataset contains frequency-domain MT transfer functions and response estimates generated following quality control and robust MT processing of the corresponding raw time-series archive. Transfer functions are provided in EDI format and represent interpretation-ready datasets suitable for geophysical interpretation, two- and three-dimensional inversion, and regional-scale analysis of crustal and upper-lithospheric electrical structure. These products were generated directly from the corresponding raw dataset and support electrical resistivity modelling and comparative geophysical investigations within the Curnamona Province.

Lineage

This dataset comprises Level 2 magnetotelluric (MT) data products derived from the raw time-series collection associated with the New South Wales component of the 2017 Curnamona Province MT survey (parent collection DOI). Raw time-series data were subjected to quality-control procedures to identify and remove contaminated, noisy, or otherwise unsuitable data segments prior to frequency-domain processing. Magnetotelluric transfer functions and response estimates were generated from the raw time-series data using LEMI MT v1.4.6 software. Processing employed robust frequency-domain estimation techniques, including remote-reference processing where suitable reference data were available, following methodologies derived from the BIRRP (Bounded Influence Remote Reference Processing) framework. The resulting transfer functions are provided in EDI format and represent interpretation-ready MT data products suitable for subsequent inversion, interpretation, and regional-scale analysis of crustal and upper-lithospheric electrical structure within the Curnamona Province. Processing parameters, workflow descriptions, software versions, and processing assumptions are documented in the accompanying README file. This dataset constitutes the authoritative Level 2 archive of processed MT transfer functions derived from the New South Wales component of the 2017 Curnamona Province MT survey and is directly traceable to the corresponding raw time-series collection.
