The pictures below show field operations carried out in western Victoria during 1999-200, using Reftek 72A-02 seismic data loggers provided by ANSIR (Australian National Seismic Imaging Resource) and CMG-T40 broadband triaxial sensors provided by JUSF (Joint University Seismic Facility).
The ANSIR reftek seismic recorder is controlled by PC. The recorder is buried while running unattended for up to 3 months, recording three channels at 40 samples per second.
The Guralp 3-component broadband sensor is placed on a concrete slab and buried beneath an upturned bucket. Burial provides protection against the elements and a low noise environment. This site in the Big desert area of western Victoria was sandy and easy to dig out. Other sites have been much more difficult.
Power for a 3-month deployment is provided by a solar panel. The above site (BD1) is in the middle of the Big Desert area of NW Victoria. This station operated from June through September 1999.
On the Yanac - Murrayville road near the BD1 station. The road is basically impassable to vehicles, 4WD or otherwise, for days after rain.

The local fauna sometimes take up residence in the solar panel fittings. This one wasn't too pleased to be evicted when we packed the station up.
