When it comes to peering beneath the Earth’s surface, geophysicists have an arsenal of high-tech tools at their disposal. But what happens when you need to track something as elusive as underground ice forming and melting in real time? Enter borehole Ground-Penetrating Radar (GPR), the underground detective that helped Peter Jung and his colleagues image frozen subsurface volumes in an experimental geological latent heat storage (LHS) system. What are GPR and LHS, anyway? Ground-Penetrating Rada
