Overview
Near-surface geophysical methods are key tools in environmental and engineering geosciences, yet interpretations based on a single modality often remain ambiguous (e.g., Wagner & Uhlemann, 2021). Combining multiple methods with complementary sensitivities can significantly reduce this ambiguity, but is frequently hampered by method-specific, closed-source software solutions. In this hands-on workshop, we introduce the open-source library pyGIMLi (Rücker et al., 2017) as a flexible framework for multi-method modeling and inversion. Participants will gain an overview of pyGIMLi’s forward modeling operators and learn how these can be coupled within unified inversion schemes. Using examples of increasing complexity, we will demonstrate how to integrate prior information from borehole data, implement structural constraints, and set up fully coupled joint inversions employing both petrophysical and structural coupling strategies. The workshop targets researchers and practitioners interested in practical workflows for combining near-surface geophysical data within an open and extensible Python environment.

Overview
The Transient Electromagnetic (TEM) method allows us to measure a response from the subsurface that then can be used to model the resistivity structure of the subsurface for applications such as mineral exploration, geological mapping, groundwater mapping and environmental studies. The depths involved depend both on the TEM instrument and the geology. The workshop will include a brief introduction to the TEM method and how we should understand the TEM responses. We will delve into how we can process the TEM responses by removing couplings and noise. We will consider how to invert the TEM responses to produce reliable resistivity models. Lastly, we will look at how we can evaluate and visualize the inversion result, both to understand the quality of the result and to present the result. The example dataset used during the workshop is a high-resolution airborne TEM dataset collected for a groundwater mapping. The understanding and the workflows that we will cover are however just as relevant for different TEM instruments and application of the TEM method. The workshop combines presentations, live demonstrations and hands-on exercises using Workbench. Registered participants will be given a time-limited Workbench license and instructions on how to download and install the software ahead of the workshop.

Overview
The workshop focuses on near-surface seismic methods with an emphasis on surface waves, bridging fundamental theory with practical engineering interpretation. The first part introduces the essentials of Rayleigh/Love-wave propagation and dispersion, survey design and acquisition, dispersion imaging and curve picking, and inversion strategies to obtain Vs models (1D/2D/3D). We will cover both active-source (e.g., MASW, multicomponent data) and passive approaches (e.g., array/beamforming concepts and noise-based surface-wave workflows). The second part features case studies linked to engineering parameters and decision-making (e.g., Vs30, stiffness contrasts, stratigraphy, site response, geohazards/infrastructure monitoring), followed by discussion. The workshop is hands-on and participants will work through curated datasets and shared scripts, with code and data examples provided to enable continued use after the course.

Overview
Go beyond the radargram and discover the physics of GPR signal propagation in the subsurface in this immersive, hands-on workshop that bridges the gap between electromagnetic theory and field reality by using gprMax, the leading open-source simulator for Ground Penetrating Radar. We will begin by demystifying the Finite-Difference Time-Domain (FDTD) numerical method, showing you exactly how waves propagate, scatter, and attenuate in complex environments. Participants will learn the basics of building gprMax models and learn how they can incorporate frequency-dependent soil properties, realistic clutter, and even detailed antenna geometries. We will also explore the cutting edge of the field, discussing and presenting some examples of how to leverage these simulations to generate massive synthetic datasets for Machine Learning and automated interpretation. Whether you are a researcher looking to validate a new algorithm or a practitioner seeking to understand complex reflections, this course provides the tools to simulate what you see in the field. You are welcome and encouraged to bring your own laptop to follow along with the course.
