More #Otemma research - in August & September, PhD students Johanna Klahold & @RuolsB of Institut des Sciences de la Terre - UNIL stayed at our basecamp to do intensive fieldwork on the Otemma glacier using their #GPR drone. #FieldworkFriday

GPR drone flying on #Otemma glacier - efficient and safe! @RuolsB and Johanna Klahold will use the acquired high-resolution #GPR data to study the internal structure of the glacier, including its flow dynamics and hydrological system. #glaciology

I‘m humbled to have received one of this year‘s Heitfeld awards. Thank you Florian Wagner for the great supervision!

🚁 @RuolsB is developing a drone based ground-penetrating radar (GPR) system for 3D/4D surveying of alpine glaciers🏔️ in order to investigate their internal dynamics with Johanna Klahold! Watch the video produced in collaboration with SPH Engineering ! 🎥 bit.ly/3DuFccm

Interested in diffraction imaging of alpine glacier GPR data? Come listen to my talk at #EGU22 on Wednesday, session CR2.1! EGU Cryosphere @egu-cr.bsky.social 👇 meetingorganizer.copernicus.org/EGU22/EGU22-58…

Testing some dye tracing equipment and cooling down from the summer heat in Vallon de Nant with @MarjoleinGevers ICE UNIL and Johanna Klahold Institut des Sciences de la Terre - UNIL earlier this week. #fieldwork

When fieldwork is done and you still need to kill some time on the glacier…

I‘m just now seeing this — a big thank you to everyone involved! 🎉 Hope to see you all again at this year‘s #EGU23!

And that’s a wrap! Thanks to all who joined #AGM2023 and shared their science and friendship! ❄️ 🏔️ We already look forward to next year’s edition in France! 🇫🇷

Hi 👋 The CRAG group from the University of Lausanne is happy to finally open its own twitter account🎉. Interested into temporal evolution of alpine glaciers? buried ice bodies in proglacial areas? hanging glacier geometries? Then please consider following us!

Come say hi 👋 tomorrow afternoon at my European Geosciences Union talk! #EGU23

Our OSPP winners from 2022! Congratulations Johanna Klahold, @Bastien_Ruols and Michelle Maclennan! #EGU23 #OSPP

Last week, some of us took part into the training course for glaciated terrain organised by the SPI on the Moiry glacier. Hazard assessment, crevasse rescue, health and safety issues... we now feel better prepared for the field season starting soon :) Thank you Swiss Polar Institute @swisspolar.bsky.social !

First visit to Otemma Glacier this summer. Shocked by the extent of glacier retreat, and it's still early in the season...

Summer #fieldwork season has finally started for us! 🎉 Last week we went to Otemma #glacier for the first #GPR campaign of the season. Time to process the data now before we go back in August to repeat the survey. 🗻 Gabriela Clara Racz @Bastien_Ruols Johanna Klahold Institut des Sciences de la Terre - UNIL

With our drone-based GPR system, depending on the field site, helicopter lifts are not mandatory to acquire high-density 3D datasets... as long as you have enough strong friends motivated to carry (very) heavy bags! 📌 Findelen glacier 1-2 : April 2023 3-4 : July 2023

Otemma acquisition 2/3 of this summer ✅ After some very cold days, the group came back with tons of data: 🛸drone GPR, 📷photogrammetry, 🧊ice drilling, 📷installation of 2 time-lapse cameras, 🌊dye tracing. And if you can't survey due to snowfall, why not build a snowman! ⛄️
