Abstract

Summary

SPECTREM AIR has been successfully acquiring data in Australian terrain since 2017 and has shown substantially better depth of penetration as well as increased sensitivity in shallow sounding with the SPECTREM^PLUS as compared to earlier systems. The higher-powered transmitter (amongst other improvements) has shown significant improvements in signal to noise ratio of the system.

The combination of higher transmitted power, wide system bandwidth and advanced data processing gives SPECTREM^PLUS the unique advantage of being able to map at depths of up to 600m (dependent on overburden conductivity), without compromising the simultaneous resolution of shallow features, thus making the system an ideal tool for exploring under cover in Australian terrain where difficult geological settings are present.
