SummaryAuScope Limited is an Australian non-profit organisation that was formed to facilitate the implementation of a world-class infrastructure system for Earth science through the delivery of a range of technologies and capabilities in data acquisition, management, modelling and simulation across the geospatial and geoscience disciplines.AuScope has 23 participating organisations including Geoscience Australia, CSIRO, universities, and State and Territory government agencies. The proposed utilisation of archived TerraSAR-X SAR data is a component of AuScope’s Australian Geophysical Observing System (AGOS) which is funded through the Australian Government’s Education Investment Fund (EIF3). AGOS is designed to augment existing AuScope infrastructure with new capability that focuses particularly on emerging geophysical energy issues.AGOS is a nationally integrated research infrastructure platform focused on delivering the understanding of the physical state of the accessible crust that is crucial to meeting secure, sustainable future energy needs.AGOS brings together over 100 individual experts in seismology, geophysical modelling,surface and subsurface (borehole) geophysics, space geodesy and remote sensing.The research will specifically focus on the precise characterisation of surface deformation using Interferometric SAR (InSAR) and will facilitate the increased use of SAR data for Earth observation applications in Australia. Access to TerraSAR-X SAR data will enable the development of an Australian data portal that will facilitate collaboration in geoscience research using remote sensing data.The planned data portal will enable Australian researchers to make requests for archived SAR data observed over specific study areas, and provide on-line access to the data while simplifying researcher interactions with the data providers, such as the international space agencies.Initially,this infrastructure will focus on satellite SAR data and the characterisation of crustal deformation associated with fluid injection and extraction processes in the specific geographical regions of interest, such as the Gippsland Basin in Victoria, the Perth Basin in Western Australia, the Surat Basin in Queensland and the Murray Darling Basin in south-eastern Australia. The major scientific objectives of our research are to: ·Monitor and investigate the crustal deformation associated with the effects of groundwater, coal-seam gas and other hydrocarbon extraction and CO2 sequestration processes in Australia using InSAR. ·Investigate the inter-seismic, co-seismic and post-seismic deformation associated with earthquakes (past and future) in Australia using InSAR. ·Develop novel techniques for measuring and modelling surface deformation using integrated InSAR, Global Navigation Satellite System (GNSS) and other geophysical data. The TerraSAR-X data will be the basis for peer-reviewed research publications in high-impact journals and informing public policy. Furthermore, we are seeking DLR approval to make the TerraSAR-X data available on a Creative Commons basis (open access) for use by the Australian research community following completion of the proposed research. The data would be added to the Auscope data portal.
