Sunday March 24, 2024

Please Note:  When registering for Short Courses, be aware that 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. 

Full Day courses include morning and afternoon refreshment breaks and lunch.

SC-1:  A one-day intro to the transient electromagnetic method (TEM) for mapping of the shallow geology, overview of theory and applications.
Instructors:  Esben Auken, Pradip Kumar Maurya, TEMcompany, Denmark 
Date: Sunday, March 24, 2024
Time:  9:00 am - 5:00 pm

Course Description: 

Description: Transient Electromagnetic (TEM) is not a new geophysical method but it has not really gained as much attention as other methods like imaging with multielectrode systems or ground conductivity meters. The reason is probably that both the instruments and the interpretation software has been hard to use and very expensive. With all the new technology which has reached the world in the last decade 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 method works, how measurements are carried out and how they are interpreted. We will focus on imaging of deep laying groundwater and shallow monitoring problems. 

The course contains the follow blocks:
1. Basic understanding of how a TEM measurement works
2. Linking a case target to the best measurement configuration
3. Measurements with single site instruments, towed systems and airborne systems
4. Field demo of a typical and modern single site instrument
4. Processing and interpretation of data
5. Cases solved with single site and towed systems.

For the hands on and field demo we will use state of the art instruments from TEMcompany and modern software from Seequent.

SC-2: From AEM data and boreholes to geologic models. Workflow and examples.
Instructor: Tom Martlev Pallesen, i-GIS
Date: Sunday, March 24, 2024

Course Description:

Geological models can be made in different ways and for different purposes. This course focuses on geologic models in the context of groundwater management (hydrostratigraphic models).  Huge amount of money is spent collecting data over time. Often data are stored in many different places, digital as well as analogue, or in file formats proprietary for specific software programs. A good data hygiene is important for future use of these data.
The course will introduce you to different often used data types (and formats), such as boreholes, geophysics (especially AEM data), logs and groundwater chemistry, and how they can stand alone as well as support each other. We will discuss pros and cons, data uncertainty on different data types, and how to deal with it.  The course will introduce you to different modeling approaches, from the manual cognitive approach, to approaches using supervised machine learning and geo-statistics. We’ll look at the concepts of layered hydrostratigraphic models and voxel models. We’ll also demonstrate how a voxel model can be made very quick based on a AEM resistivity grid.  All this will be discussed in a context of usability: How can the results and visualizations be used for informed decision making and qualified communication with stake holders and the public.

Keywords: Geologic models, aquifer mapping, isopach maps, profiles, volume calculations, recharge areas, data types and uncertainties.

SC3: RES2DInv and RES3DInv Resistivity and Induced Polarization
Instructor: Laura Quigley, SEEQUENT
Date:  Thursday, March 28, 2024

Course Description:

Join us in this instructor-led course to learn a comprehensive workflow for induced polarization and resistivity in RES2DINV and RES3DINV.  This course uses hands-on activities to demonstrate importing data, removal of bad data points, data inversion, model discretization, damping/smoothing settings and creating pseudo sections. Participants will also take away an overview of current best practices for resistivity and IP surveys.

What will the course cover?

  • Introduction to RES2DINV and RES3DINV
  • Basic theory of IP and resistivity surveys
  • Working with .dat files and related conversions
  • Processing 2D and 3D time-domain and frequency-domain data from dipole- dipole, pole-dipole, pole-pole, and gradient survey configurations
  • Handling different instruments and arrays
  • Performing interactive quality control
  • Adding georeferencing and topographic information
  • Plotting values in pseudo-section format
  • Collate data into RES3DINV format
  • Display sections

SC-4:  Electrical Resistivity Imaging for waterborne applications
Instructors:  Dimitrios Ntarlagiannis, Rutgers University, Newark; Sina Saneiyan, University of Oklahoma
Date:  Thursday, March 28, 2024

Course Description:

Electrical resistivity imaging (ERI) is one of the most commonly used field geophysical methods on land applications. Waterborne applications, especially for shallow surveys, are not very common. With this course we would like to highlight the potential that exists for waterborne ERI applications, show the advantages it can offer, and discuss shortcomings. We will offer a comprehensive course, with a short introduction on ERI, followed by survey design and data processing specialized for waterborne surveys.  While not strictly required, having a Windows based pc is highly recommended for the hands-on component of the course. We will issue short course licenses for the use of proprietary software (Aarhus workbench – Towed ERT module); open source software (ResIPy) will also be used

The course will feature the following topics:

  • Introduction to ERI
  • Waterborne ERI advantages and limitations
  • Survey design
  • Forward modeling for waterborne surveys
  • Data processing and inversions using proprietary and open source software
  • Hands on practice with real life data
