SAGEEP 2025/Munitions Response Meeting (MRM) Short Courses
Full Day courses include morning and afternoon refreshment breaks and lunch.
Transient Electromagnetic Method (TEM) for Subsurface Mapping – Theory, Interpretation and Survey Design
Course Description:
Transient Electromagnetic (TEM) is not a new geophysical method but it has not really gained as much attention as other methods like imagining with multielectrode systems or ground conductivity meters. The reason is probably that both the instruments and the interpretation software were hard to use and very expensive. With all the new technology which has reached the world in the last decay this is the past and the method is now fast, easy to use, and instruments have dropped dramatically in price.
In this course, we will explain how the TEM method works. We will then link the theory to design of a survey and how parameters like depth of investigation , how measurements are carried out and how they are interpreted. We will focus on imagining deep laying groundwater, shallow monitoring problems and exploration for minerals.
The workshop contains the following blocks:
1. Introduction
2. Basic understanding of how a TEM measurement works
BREAK
3. Measurements with single site instruments, towed systems and airborne systems
4. Linking a case target to the best measurement configuration
LUNCH
5. Field demo of a typical and modern single site instrument
6. Processing and interpretation of data
BREAK
7. Cases solved with single site and towed systems
Ground Penetrating Radar - Principles, Practice and Processing
Course Description:
This GPR course is designed for novice and experienced GPR users alike. The curriculum begins with the fundamentals of GPR theory, GPR system engineering basics, factors and physical principles affecting GPR wave propagation and attenuation, proper selection of GPR frequencies for a particular subsurface investigation, and an overview of applications of the method. The course also addresses GPR muti-channel array systems (MCGPR) and 3D imaging as well as precision positioning with both GNSS systems and introduction to robotic total stations.
A portion of the day involves practical field work whereby both 2D and MCPR array data will be collected at a predetermined site. After the field data collection is complete, attendees will process both the 2D and 3D data. Integration of these data with programs such as Esri field maps and Google Earth will also be covered to complete the process and visualization of the data.
3D Geophysical Sensor Mapping in GPS-denied Areas with Proxim's Topaz SLAM-based mobile mapping system
Instructor: David Duggins
Time: 8am - 5pm
Course Description:
This course will familiarize you with the basic operations of Proxim’s Topaz SLAM (simultaneous mapping and location) system including building a reference map, geo-registering that map, then using that map to generate GPS data in real time. This allows the operation and geo-location of geophysical sensors in environments such as wooded or urban areas where GNSS is intermittent, denied, or less accurate without needing a GNSS device.

Please Note: When registering for Short Courses, please note: You can only sign up for one Short Course on Sunday and 1 Short Course on Thursday since Short Courses on the same day run simultaneously.
SC-1: Take a seismometer, wait a few minutes, and… see what you get
Instructors: Prof. Silvia Castellaro, Riccardo Castagner
Date: Sunday, April 13 2025
Time: 8:00 am - 4:00 pm
Course Description:
Seismometers are used to record earthquakes and microtremor. Over the last 20 years, the latter have been extensively used to assess the ground resonances by means of the H/V technique.
Are the peaks in the H/V ratios real resonances? How to understand it? And if they are not, how to interpret them? In this course we will see many applications of the H/V technique and of the H&V “variation”. How to use these method to do seismic stratigraphy, how to use it to estimate the Vs (and Vs30), how to obtain the dispersion curves (MASW) in a simple and fast way, just with a single seismometer and a trigger and not even a laptop. Our smartphone will be enough.
The course will be organized in the following blocks:
- Seismic microtremor: its characteristics. How to remove the source effect and unveil the path effect
- Basic principles of data acquisition and analysis
- 1D cases: the H/V approach
- 2D cases: the H&V approach
- Seismic stratigraphy by using single-station measurements
- Vs, Vs30: how to quickly get shear wave velocities by using single-station measurements± triggers
The course is hands on and includes a field demonstration. For participants who wish to work on their laptops and/or smartphones, instructions for installation will be provided a few days before the course (please send your email address to [email protected]; attention MASW Short Course).

Seequent UX-Analyze: Dynamic Data Processing and One-pass Classification
Instructor(s): Laura Quigley, Seequent
Date: Thursday, April 17
Time: 9am-5pm
Course Description:
Join Seequent in this instructor-led course that will walk through how to process dynamic one-pass AGC (advanced geophysical classification) data. This course will include how to process your dynamic data, including IVS (instrument verification strip) data, data quality control, and the use of informed source selection for target picking. Using the one-pass classification workflow within Oasis montaj UX-Analyze, you will produce a classified source database, which can be used to produce a dig list of TOI’s (targets of interest). Course participants will be provided with a two-week subscription for Oasis montaj UX-Analyze. Participants will need to download and install the latest version of Oasis montaj, on a laptop that they can bring and use for the course.
