SUMMARY:Hitting the right frequency - not all conductors are created equal
DESCRIPTION:Date: May 23\, 2025 \nTime: 12:00 PM \nEvent Format: In-person Presentation \nLocation: Saskatoon\, SK \nHosting Organization: Saskatoon Geoscience Discussion Group \nEvent Summary: Airborne time domain electromagnetic (EM) surveys are indispensable tools for subsurface exploration\, particularly in resolving conductors at depth. Their depth of investigation depends in part on transmitter frequency and moment\, as well as the noise levels of the receiver. In this study\, we present a comparison of conductor detection and resolution capabilities of the Xcite time-domain EM system operating at frequencies of 15 Hz and 30 Hz. Through detailed modelling of data collected over a study area\, we investigate the effect of these frequencies on the system’s ability to detect and resolve conductors. Methodologically\, we describe the parameters and settings used for both frequencies and outline the data analysis techniques used. Our results reveal significant differences in conductor detection and resolution between the two frequencies. The practical implications of our study extend to improvements in survey design\, suggesting that the choice of frequency can significantly impact survey outcomes. Moreover\, our findings underscore the importance of further research to enhance understanding and optimization of airborne EM survey methodologies. Presented by Vessela Hobson\, Chief Geophysicist Axiom Geophysics & Remote Sensing. \nHow to Register: Click here for more information and to register. \nEvent Contact: Saskatoon Geoscience Discussion Group: https://stoongeogroup.ca/ \nDisclaimer: The views expressed during this event are those of the hosting organization and do not necessarily represent the views of APEGS.
