Short summary
We demonstrate the feasibility of imaging vertical freezing boundaries using borehole ground-penetrating radar (GPR) in experimental geological latent heat storage, where part of a shallow Quaternary aquifer is frozen. To gain insights into the current thermal state in the subsurface, we assess the frozen volume dimension. We show that a combination of crosshole and reflection measurements allows us to image the ice body with high accuracy in the challenging environment of saturated sediments.
