AuScope Subsurface Observatory
The AuScope Subsurface Observatory provides geophysical monitoring and rock property analysis, to support crustal geological modelling, geohazard assessment, mineral exploration, and infrastructure planning.
Our equipment pool leverages nationwide drilling efforts, supporting major programs like the Stavely Project. Our capability in geothermal applications will help to translate and accelerate recent advances in this sector. Our strategic seismic monitoring program targets zones of high historical seismicity and critical infrastructure. Operating from UoM, we align with experts in seismic hazard, crustal heat flow and energy/resource transition.
The AuScope Subsurface Observatory at the University of Melbourne has a 12-year history, following its predecessor, the Australian Geophysical Observing System. Several past staff members have contributed significantly to its development. The observatory conducts real-time seismic monitoring, notably in Gippsland and Central South Australia, where networks detect earthquakes almost daily. We aim to maintain a real-time seismogram feed via the school website, with additional monitoring possible through gravimeters and tiltmeters, creating a comprehensive subsurface data stream similar to weather feeds.

Petrophysics Laboratory
AuScope's Petrophysics Laboratory is located in the McCoy Building at the University of Melbourne were we house a number of world-class instruments. Our knowledgeable staff can help guide students and researchers in using this equipment in their own studies. We are also equipped to accept a range of different sample types, from 'hot' rocks to building insulation, for expert analysis.
If you want to learn how to use our equipment or send samples for us to measure, please contact us here:
Thermal Conductivity
For over two decades University of Melbourne staff have been instrumental in developing new techniques, instruments and global standards for rock thermal property measurements. Our Petrophysics Laboratory is one of the premier destinations in the country to measure thermal conductivity, thermal diffusivity and specific heat capacity across a range of different sample types.
C-THERM Trident
Quick, simple and effective. The Trident is a transient instrument that can produce results in minutes and operate in altered ambient temperatures (from -50C to 200C). The Trident is calibrated for most sample types (insulation to rock) and only tests a small portion of the sample at a time which means that can determine thermal heterogeneity.

Portable Electronic Divided Bar
Reliable and thorough. The Portable Electronic Divided Bar Mk II (PEDB) is a steady state instrument with an insulated interior making it the best choice to analyse bulk thermal properties. The PEDB is also equipped to measure specific heath capacity and thermal diffusivity when combined with a known sample density.

TCS Thermal Conductivity Scanner
Rapid core analysis. The Thermal Conductivity Scanner (TCS) can rapidly measure and image the thermal properties of core lengths (up to 1 meter at a time). It reports on the homogeneity and anisotropy of a sample; and can as measure thermal diffusivity and specific heat capacity when combined with a known sample density.

The primary purpose of our supporting instrumentation is to determine the physical properties of samples in order to better define their thermal attributes. However, these instruments have also been utilized by a number of different projects from geophysics to archaeology.
Vacuum Chamber
Our Abbess vacuum chamber is a high volume, 60cm cube unit that can produce a vacuum with a pressure of 29.92 inches Hg (100,000+ Pa) or better. It is primarily used to introduce water into rock samples for the purpose of determining density via Archimedes' principle.

Tenney Environmental Chamber
The Tenney Environmental Chamber can produce temperatures between -50C and 200C in multi-staged time controlled programs. It allows us to take thermal measurements in altered ambient temperatures and calibrate instruments for use in extreme environments.

Olympus Delta Portable XRF
The Olympus Delta XRF scanner is a non-destructive device able to rapidly measure the trace element composition of a sample. It is primarily used to determine the heat production of a rock from its radiogenic (K, Th, U) contents, but has also been used in archeological studies.
