The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) time series data from Victoria

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative, long-term initiative involving the Australian federal and state/territory governments in conjunction with research organizations. This nationwide project aims to collect long-period magnetotelluric (MT) data at approximately 3,000 sites across the Australian continent, with the objective of mapping its electrical resistivity/conductivity structure. The project provides valuable insights into Australia's lithospheric architecture and tectonic evolution, as well as supporting resource exploration.

The AusLAMP Victoria project was a collaboration between the Geological Survey of Victoria and Geoscience Australia (GA). The data were acquired using Australian National Sounding and Imaging Research Infrastructure (ANSIR)/AuScope and GA's MT instruments from 2013 to 2017. All processed datasets and models were previously published through the associated links in this product.

This release comprises time series data provided in both the original format and the MTH5 hierarchical format. These formats ensure that users have access to the data in its initial format as well as in a self-described format. The original recorded data were converted into MTH5 format using the open-source MTH5 Python package (https://github.com/kujaku11/mth5). The creation of this product was made possible through Resourcing Australia's Prosperity initiative (https://www.ga.gov.au/scientific-topics/resourcing-australias-prosperity).

We acknowledge the traditional landowners, private landholders and national park authorities within the survey region, without whose cooperation these data could not have been collected.
