KEGS December Talk

Our next KEGS talk is happening on December 13th at 4:00 PM. The talk will be hosted in-person and online. 

TitleAn Update on Two SQUID-based Airborne Technologies

SpeakerJonathan Rudd, President and Director, Dias

Date: Tuesday December 13th at 4:00 PM

Location: University of Toronto, Department of Earth Sciences, Room ES2093 (22 Ursula Franklin Street)

Abstract:  Dias has been working with Supracon AG over the last 5 years to develop a SQUID-based passive source airborne electromagnetic survey system. This system, named QAMT is now commercially-available. QAMT measures three orthogonal components of the magnetic field. The sensor platform is mechanically damped and residual motion is characterized with an IMU in order to deliver low-noise, oriented 3-component data. Using a base station, we are able to deliver tipper, apparent resistivity, and inversion models.

Two years ago, Dias deployed the QMAGT system, which is an established technology that delivers full tensor magnetic gradiometry (FTMG) data. FTMG provides the directional information that improves the interpretation of remanence and source geometry. The low temperature SQUID sensors produce highly sensitive and accurate data that improves resolution. Applications to date have been in exploration for diamondiferous kimberlites, nickel, iron ore, and gold. Dias will be deploying a second QMAGT system early in 2023.

Bio: Jonathan Rudd is a professional engineer and geophysicist who has over 30 years of experience in the application of borehole, ground and airborne geophysical methods to geological challenges. Jonathan has worked in senior management for the last 12 years with a principal focus on technology development and business development. He is a past-president of the Canadian Exploration Geophysical Society, and is currently President and Director of Dias.

KEGS Ottawa Christmas Party

First: If you received this message and you no longer want to be on the KEGS Ottawa email group, please email me, and I will take you off the list. It has been a long time since we used this email group, so it wouldn't surprise me if it will need a lot of updating.

Next, the reason for this message: I thought it would be nice to have a KEGS Ottawa Christmas party, especially because we cancelled our summer BBQ this year. Please try to distribute this invitation to others who may be interested in joining KEGS Ottawa, especially any students.

At the party, we will be presenting KEGS Foundation scholarships to two local PhD students, Taylor Tracey Kyryliuk and Fateme Hormozzade Ghalati. We can also have a discussion to see how much interest there would be in re-starting the KEGS Ottawa presentations and ideas for available locations for any potential future meetings.

We (SGL) will provide something to drink for the party. 

What: KEGS Ottawa Christmas party 

When: Monday December 19, from 5pm to 7 pm.

Where: 2nd floor, Sander Geophysics office, 260 Hunt Club Rd. Please enter by the door at the south east corner of our building.

Who: Anyone interested in KEGS Ottawa; friends and spouses also welcome. RSVP to me,, so we have some idea of how many people to expect.

KEGS 2023 Symposium - Call for Abstracts

Mark your calendars - KEGS is excited to announce the return of the annual Symposium to be held the Saturday preceding the 2023 Prospectors and Developers Association of Canada (PDAC) Convention Toronto, Canada. The event is planned to be held in person on March 4th, 2023.

At this time KEGS invites you to submit an abstract on the following suggested topics: 

  • Geophysics for Critical Mineral Exploration
  • Open Source Tools in Exploration Geophysics
  • Artificial Intelligence and Machine Learning Applied to Exploration Geophysics
  • New Developments (Data Acquisition, Processing, and Interpretation)
  • Integrated Case Histories

Abstract Submissions 

Short abstracts are to have a 400-word limit. An abstract template is available here.

The deadline for submission is Friday, December 9th, 2022.  

Please submit your abstract here, and include "KEGS 2023 Symposium Abstract" in the subject line.


Nominations for a new KEGS executive member is open! 

Interested in joining the 2023 KEGS executive? Know someone who might be? If you or someone you know would like to volunteer to run for the 2023 KEGS executive position of Secretary-Treasurer, please contact one of the KEGS executives. The executive generally meets virtually once a month between September and June to organize our monthly talks and events. We welcome members who live outside of the GTA to put their name forward.


Membership Renewal

Don't forget to renew your KEGS membership for 2023! The membership costs remains unchanged at $50 + HST for regular members and $25 + HST for students. While at it, why not consider a donation the KEGS Foundation to help foster and support geophysical education at Canadian Universities. 


KEGS 2021 Financial Statements

Financial reports for KEGS FY 2021 have been be issued and posted to the website under the Member's Area.

  • Scholarship award presentations continued in November with Directors attending meetings in Vancouver (BCGS), Winnipeg and Saskatoon to present scholarship awards, as well as department seminar at Laurentian.
  • Very successful 6-à-8 soirée de la géophysique held on November 22 during Québec Mines. Merci aux organisateurs et aux commanditaires Géophysique GPR International – Géosig et Géostack!
  • Presentations of balance of scholarships to awardees being arranged, in Ottawa at Sander Geophysics (5-7 pm, December 19), Western and Queen’s, with awards of the premier Collett Graduate Scholarship as well as the WAMIC, GSC Pioneers and KEGS Pioneers Scholarships. Directors look forward to meeting various awardees and supporters at these in-person meetings.
  • The Board of Directors warmly welcomes Prof. Richard Smith, Laurentian University, as a new Director.
  • Thanks extended to recent donors, notably the Steers family and the sponsors of the soirée on during Québec Mines: Géophysique GPR International – Géosig and Géostack.
  • Additional donations encouraged to support core scholarship program.
