Earth Imaging and Structure

Earth imaging and structure infrastructure investments will enable the geoscience community to build an increasingly clear and rich picture of the subsurface.  This component builds on the resources of the ANSIR National Research Facility In Earth Sounding.  Based at the ANU, ANSIR has a pool of state-of-the-art seismic equipment suitable for experiments on a wide variety of scales, from the investigation of geologic structures on environmental and mine scales through to studies at the continental scale of the entire lithosphere. 

 AuScope investment for this component will fall into three main categories:

1. An upgrade of existing passive seismic and magnetotelluric (MT) equipment to present state-of-the-art.  This includes the purchase of broadband seismic recorder systems based at the ANU, MT broadband systems based at University of Adelaide and the ANU, and MT low frequency systems based at the University of Adelaide.

2. The acquisition of ~250 line-km per annum of seismic (reflection and portable instrument) and MT imaging.  The AuScope investment will enable the university-based research community to have a seat at the proposed National GeoTransect planning table, and to use its 250 line-km contribution to leverage access to a much larger Earth Imaging dataset.

3. Operating and maintaining the instrumentation, and for coordinating and managing the AuScope National GeoTransect Program.  These tasks include ensuring that the data / information from transects is processed, stored and managed appropriately, and in liaising with the AuScope Grid manager to ensure broad access and interoperability.

AuSREM

The Australian Seismological Reference Model (AuSREM) has been designed to bring together existing information on the Australian continent of many types, and provide a synthesis in the form of a 3-D model that can form the basis for future refinement from more detailed studies. For more information visit the AuSREM page.

For more information on current and potential projects or accessing AuScope’sEarth Imaging and Structure infrastructure component for a project of your own please contact the Program Director.
