Geophysicist, President & Owner
About the Owner: Mr. Mihelcic is an Applied Science '88 Geological Engineering (Geophysics Option) graduate of Queen's University at Kingston and '95 MBA graduate of Ivey Business School at the University of Western Ontario in London. He enjoys designing and implementing off-the-shelf components and technologies to make ground geophysical surveys easier and therefore more cost effective. He also writes C++ software to streamline processing and interpretation.
Rover Geonics EM34-3XL Surveys
The Geonics EM34-3XL ground conductivity meter can be applied in 'rover-mode' for high resolution coverage in a short amount of time. The onboard 'Archer2' datalogger collects real-time GPS at 1-second intervals tagged to Apparent Conductivity readings at 5x per second. The low-stretch tow-strap keeps the distance between the receiver and transmitter sleighs close to the optimum 'nulled' 20-metre separation.
The same specially configured plastic sleighs with no metallic components used for the IMAGEM rover surveys are also used here - allowing for stable coverage.
The mode of operation in the case displayed here is 'vertical dipoles, 20-metre Tx-Rx separation' for effective depth penetration of 30 metres.
A Geonics EM31 survey is typically also completed for shallower depth coverage up to ~6 metres.
A Garmin GPSmap 62stc is used for navigation:
In-house software CVNAV is used to correct the plotting position to half-way between the transmitter and receiver. A 1-second latency correction to account for GPS positioning versus reading is also applied. This software is the same as used for all Cesium Mag and other DGPS Rover Surveys.
