Imaging englacial and subglacial drainage networks with UAV-based 3D GPR
Irving, James
Meltwater drainage through glaciers strongly influences ice dynamics and related hazards, yet detailed observations of active englacial and subglacial networks remain scarce due to challenges in direct observation. We present a novel high-density, UAV-based 3D ground-penetrating radar (GPR) survey of Switzerland’s Otemma Glacier, integrated with dye tracing experiments, photogrammetry and hydraulic potential modeling, to map internal water pathways with unprecedented spatial resolution and cover
