Beautiful day for fieldwork in Dischma, but the effects of this year’s drought are hard to miss. River levels are so low that our pipes are now hanging above water. Hoping next week’s forecast rain brings relief to these extreme low-flow conditions. @slfdavos.bsky.social @cryoscope.bsky.social

In barely 10 days after the last snow for the season, we have lush greenery and higher streamflow. Low EC values suggest high snow/glacier melt contributions. The ISCO keeps sampling the stream twice a day

Happy to share this @eos.org Editors’ Vox piece following our recent review on tracer-aided mixing models It explains how water’s natural fingerprints can help us trace its hidden journey through Earth’s #CriticalZone eos.org/editors-vox/... agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Tracing Water’s Hidden Journey Through the Earth’s Living Skin - Eos

Water’s natural fingerprints reveal how it’s stored, mixed, and released through the Earth’s Critical Zone, potentially improving Earth System models in a rapidly warming world.

It's really strange to get snow in the middle of May in Dischma. The ISCO continues sampling every 12 hours, will be interesting to see if the signature of the recent snow could be traced in the stream

With spring melt increasing discharge, the ISCO started overflowing a bit. Funny scenes with floating vials inside Snow has melted very early in Dischma and it will be interesting to see how summer low flows fare. This is the new climate normal now!

Snow is almost gone now and the ISCO piping had to be replaced. Stream conductivity suggests a lot of snow contribution to streamflow. We now installed a new palmex rain sampler to fix the problem of evaporation of rain. Looking forward to high-frequency sampling during spring

After a month, the ISCO is finally working. Snowpack was vertically homogenised in terms of density and had a lot of liquid water Our Msc student Thomas, who is making the snow pits, will start his isotope sampling in Svalbard later this spring. Lots of ongoing @cryoscope.bsky.social work

With snowfall in the last few days, our ISCO piping is frozen, and we can barely see the river. It was interesting to notice overflow conditions, with a thick ice layer separating the old snow and the recent snowfall. It's really hard to get daily stream samples in these conditions :(

Dense cloud coverage over the Swiss Plateau keeps sunshine away for much of the winter in places like Zurich. But above the clouds, there are blue skies and lovely sunshine. ☀️☁️

Last Dischma samples for 2025. The ISCO continues to struggle with the cold weather, with water samples continuously freezing in the bottles. A few springs that I used to samples have also frozen up and stream levels are really low. Snowpack continues to be very shallow (~21 cm).

Snow has arrived in Dischma,with ~20 cm of accumulated snow. The snowpack is cold with surface snow temperatures around -11 °C. Unfortunately, our thermal insulation couldn’t keep the ISCO water samples from freezing 🥶🥺 Time to change the insulation?

First snow samples of the season from Dischma! ❄️ I have managed to keep the ISCO running every 6-hours in the past few weeks to capture potential ephemeral snowmelt signals in stream isotopes. Interestingly, EC rises at night and drops during the day, suggesting some melt influence in streamflow.

After a year of loyal service, our ISCO gave up on us in Dischma 😭 On a brighter note, we have got another picarro up and running 🚀 Hopefully this means we can finally keep pace with the mountain of samples piling up. Not sure if it's a good problem to have 😁 @cryoscope.bsky.social
