Remote Sensing of Heat: a Review of Potentially Useful Methods and Instruments in the Quest for Innovative Exploration Approaches

Abstract

Direct sensing of surface radiant heat, and buried temperature anomalies by remote methods deserves more attention because of the potential uses these methods can offer the geothermal exploration industry. Many instruments and methods exist, but their data have been largely ignored to date. This paper provides a review of available, and yet to be tested methods, and their relative merits. In summing-up, focus is aimed at methods to measure surface radiant heat. There are ongoing challenges with data interpretation, new mathematical methods and software development. Finally, a calibration range is advocated in one or more of Australias more prospective regions for the purpose of testing and consolidating better use of geophysical methods, and developing diagnostic tools kits for exploration.
