Johanna gave a truly outstanding presentation to a large audience of colleagues, friends, and family. With clear explanations and striking visuals, including numerous videos and animations, she made complex glacier-geophysics concepts accessible to a broad audience. <\/p>\n\n\n\n<p>Johanna&#8217;s thesis involved multiple demanding field campaigns on the Otemma Glacier and the analysis of a very large volume of data. Using high-resolution 3D and 4D GPR, she successfully imaged and monitored the evolution of the near-terminus englacial and subglacial drainage system throughout the melt season and between years. <\/p>\n\n\n\n<p>Congratulations, Dr. Klahold!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995-1024x768.jpg\" alt=\"img 7995\" class=\"wp-image-1622\" srcset=\"https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995-1024x768.jpg 1024w, https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995-300x225.jpg 300w, https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995-768x576.jpg 768w, https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995-1536x1152.jpg 1536w, https:\/\/wp.unil.ch\/crag\/files\/2026\/01\/img_7995.jpg 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">img 7995<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>On Thursday at 3pm, Johanna Klahold successfully publicly defended her PhD thesis, entitled \u201cHigh-resolution imaging of englacial and subglacial hydrology with 3D and 4D ground-penetrating radar\u201d.
