🕷️Survey on ticks in Graubünden 🕷️⁠ 📋@annekempel.bsky.social want to find out at what altitudes these arachnids are now living in Graubünden – as climate change has caused them to migrate to higher ground. ⁠ ⁠ 💡Take part! limesurvey.wsl.ch/index.php/33... 📸 IPZ-FS / Francis Schaffner⁠ #SLF #Ticks

🪲Looking for #insects, 🌱making seed bombs, ❄️testing snowballs for hardness and 🧊thawing #permafrost – that’s what the holiday activity programme at the SLF looked like this week. The #snowball fight at the end is, of course, a must. 😎 📸SLF #SLF #SLFDavos #holidayactivity #kids #experiments

🔥SLF #forest #fire expert Julia Miller joins us for an interview to explain why so many 🌲forests in Europe are burning, why the situation is not going to improve - and why such #extreme events will become more frequent in the coming decades. More: www.slf.ch/en/news/were... 📸 Roman Oester / SLF

New #flood projections based on hourly rather than daily #data show that 100-year floods could be 5 to 15 per cent more intense in the future and occur every 45 to 80 years. The main reason are short, more intense heavy #rainfall events. More: www.slf.ch/en/news/how-... 📷️ M. Brunner / SLF

Plenty of water, fine-rich sediments and a steep slope – that's all it takes to create a hazardous #debrisflow. #SLF researchers studied ten different debris-flow channels in #Switzerland to gain a fuller understanding of flows. More: www.slf.ch/en/news/reci...

Recipe for hazardous debris flows

Research into ten Swiss debris flow channels is yielding valuable data for debris flow calculations.

To be prepared for the future, we need to understand the past and the present. That is why our researchers at WSL and @slfdavos.bsky.social collect data, build models and carry out observations. Read about how they do this and what they discover in the DIAGONAL magazine www.wsl.ch/en/publicati...

This week we welcomed Samuel Weber from SLF Davos to our glaciological seminar! He presented a physically based framework for understanding permafrost rock slope destabilization, combining lab experiments, field data, and mechanical modelling, with the Matterhorn as study site. @slfdavos.bsky.social

Time to set up our @bugnet.bsky.social field sites for the season in @slfdavos.bsky.social after the snow has melted: Carole Schöpfer doing a great job in assembing all #opentopchambers and in creating this nice video 🥰

"Die Vorstellung eines Klebers, der den Berg zusammenhält, ist für grosse Hanginstabilitäten [...] unpassend", sagt #SLF Forscher Robert Kenner über die gängige Meinung, #Permafrost sei wie ein Kleber. Details: www.slf.ch/de/news/perm... 📷️ 1: Marcello Negrini / 2: Stefan Suhner #CERC

In CH, #forests account for 20-30% of total #snow storage in #winter. On south-facing slopes, snow usually lingers longer in alpine forests than in the neighbouring open terrain. On north-facing slopes, the opposite is true, as SLF researchers found. More: www.slf.ch/en/news/how-... 📷️ V. Haagmans
