The 2022 Outstanding Student and PhD candidate Presentation (OSPP) Award is awarded to Johanna Klahold for the poster/PICO entitled:

Diffraction imaging of alpine glacier GPR data (Klahold, J.; Schwarz, B.; Bauer, A.; Irving, J.)

Johanna Klahold is a PhD candidate under the supervision of Dr. James Irving at the University of Lausanne (UNIL), Switzerland. After completing the IDEA League Joint Master’s Programme in Applied Geophysics at ETH Zurich, Delft University of Technology, and RWTH Aachen University, she started her PhD within the UNIL Institute of Earth Sciences in the beginning of 2021. Johanna’s PhD project focuses on developing novel processing and analysis strategies for 3D and 4D high-density glacier GPR data, with the aim of obtaining new information on the geometry and evolution of the glacial hydrological system.
Johanna’s current research explores the potential of state-of-the-art diffraction imaging methods from the field of exploration seismology for the analysis of alpine glacier GPR data. The latter typically contain a vast amount of diffraction events, which are assumed to be caused by englacial and subglacial meltwater channels and voids. The awarded presentation showed a first application of diffraction separation and imaging procedures to high-density glacier GPR data acquired on the Haut Glacier d’Arolla (Valais, Switzerland) in order to investigate the correlation between the diffracting structures and the englacial and subglacial hydrological network.
