Frank Arnott (1951-2009)

Frank Arnott was an 
exceptional exploration
industry leader

He championed innovative techniques that maximise the value of the multidisciplinary data that underpin modern exploration campaigns.

Frank always looked for new and innovative ways to improve data processing methodologies and integrate multidisciplinary exploration datasets. The development of his GeoExpress 2000 product was the culmination of many years of hard work. It is fair to say that Frank was at least a decade ahead of the industry in his thinking, with many of the concepts he was advancing coming to fruition today.

Frank was never constrained by convention and he was just as happy working on global datasets as he was working at the prospect scale. He was equally comfortable engaging with academia as he was with industry and often sought innovation in unfamiliar areas such as biomedical imaging, bringing back ideas to help solve exploration problems. His enthusiasm was infectious and he was a wonderful mentor, a talented scientist, always passionate and committed to geophysical exploration.

Example of Frank's work

Post the discovery of the Las Cruces discovery in 1994 by Riomín Exploraciones SA (a subsidiary of Rio Tinto plc), Frank Arnott was tasked with integrating and visualising the variety of geophysical, petrophysical and geological datasets collected over the deposit. When Frank reviewed earth science software packages available in 1996 , they all fell far short of the project team requirements. In a stroke of innovation, Frank looked to other fields and saw AVS Express, (software designed at that time for the medical industry) and set about to modify/adapt it for application in earth sciences.
Today, Frank would have been the first to say the images in the accompanying paper on his work on the Las Cruses deposit are fairly orthodox. However at the time, the ability for geoscientist’s to easily and quickly integrate and visualise a variety of datasets (including derived products such as geophysical inversions) in 3D and have the ability to apply filters, colour stretches, isosurfaces instantaneously was truly revolutionary for the earth sciences.  Read the abstract here
