ANSIR is operated jointly by the Research School of Earth Sciences of the
Australian National University, the School of Earth and Environmental Sciences at
the University of Adelaide and Geoscience Australia.
ANSIR was created as a Major National Research Facility in 1997 to encourage
and assist world-class research and education in the field of seismic
imaging of the Earth. Since 2007 ANSIR has operated in conjunction with the
Earth Imaging component of the AuScope facility established under the
NCRIS scheme. AuScope funding provides support for some operational costs.
ANSIR provides support for a variety of styles of experiments in Earth Imaging.
There is 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. Thanks to ARC LIEF and AuScope support there is now a
pool of magnetotelluric equipment that can be accessed through applications to the
Facility.
ANSIR acts as a facilitation agent for Reflection Seismic Profiling since it
no longer owns any reflection equipment.
ANSIR equipment is available to all researchers on the basis of merit,
as judged by an Access Committee on the basis of a short proposal.
Researchers have to meet the project operating costs. Training is
provided in the use of the portable equipment.
Applicants for access to ANSIR equipment are encouraged to contact the
Director of the facility to discuss their needs for prospective projects
and then prepare a formal proposal.
ANSIR Equipment
The facility pool comprises both broad-band and short-period portable
seismic recorders, and magnetotelluric systems.
Portable Seismic Instruments
75 solid-state recorders are available through ANSIR with 3-component
sensors (1 Hz).
Recent demand for these systems has been high.
The facility has, in addition, a total of 40 sets of portable broad-band
seismometers and high-fidelity recorders running from solar power.
Seven instruments are deployed in
Antarctica, the remainder are available for experiments in Australia.
Demand for the broad-band instruments is generally high.
Portable Magnetotelluric Instruments
15 sets of Earth data recorders are configured for use with both seismic and magnetotelluric
sensors.
A further 20 magnetotelluric systems are available.
Some equipment is currently reserved for support of AuScope transect projects
