The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative national magnetotelluric (MT) survey for acquiring long-period MT data at approximately 2800 sites across Australia (Figure 1) to map the electrical conductivity of the continent in three dimensions. The national MT survey will provide significant additional information about Australia’s geodynamic framework as well as valuable pre-competitive data for resource exploration.

AusLAMP is led by Geoscience Australia with support and co-operation from State and Territory Geological Surveys, The University of Adelaide, and other research organisations. The long-period MT instruments (Figure 2) are funded by AuScope (non-profit company funded by the Australian Government under the National Collaborative Research Infrastructure Strategy (NCRIS)) and accessed through the ANSIR national earth-sounding instrument pool. The field data are acquired by these portable instruments on a half degree grid spacing (approximately 55 km) during a deployment of about one-month to achieve maximum sensitivity to the base of the lithosphere. AusLAMP is expected to take several years to complete, depending on available resource allocation and funding contributions from participant organisations.

Data access

Geoscience Australia intends to archive all national AusLAMP data and to establish a dedicated AusLAMP webpage as a distribution point for all data. Data and products will be released throughout the project life span. Outputs from AusLAMP will include metadata records, processed data, inversion products and reports. Data and products will be freely available to scientific research organisations, industry and the general public.
