Finally a meteorologic+soil sensor station on the UNIL campus. Real-time data visualizations will be made publicly available in 2026. This is a first step towards making our campus an environmental observatory for teaching, research and scientific outreach.

But stable water isotopes rarely tell us anything about water parcels older than 1β2 years, and even tritium often doesnβt push that limit much further dx.doi.org/10.1029/2025....

I had a very good experience with @jpgannon.bsky.social's cuahsi.shinyapps.io/HBV-model/ for a class of ~100 bachelor students with mixed backgrounds. I definitely recommend it. We need more of these educational apps!

With @ethzurich.bsky.social colleagues & friends, we decided to #StandUpForScience this afternoon to express our support for our US colleagues. Science is a common good. Thanks to all those who joined so spontaneously!

Welcome to the Bluesky account for Stand Up for Science 2025!
Keep an eye on this space for updates, event information, and ways to get involved. We can't wait to see everyone #standupforscience2025 on March 7th, both in DC and locations nationwide!
