Why do trees preferably transpire winter precipitation? 🌳💦 In our latest commentary we argue that it's not a big surprise but the effect of seasonal differences in soil water recharge. onlinelibrary.wiley.com/doi/…

In engineering, there’s always an ideal—but real-world design means innovating under imperfect conditions. UMass Amherst hosted the ASCE Northeast Student Symposium, where students built & raced concrete canoes 🛶 @mass_cee #ConcreteCanoe #UMass #ASCE #Engineering

I have not been on Twitter for a while...but I give it another shot for promoting the latest chapter of @GiuliaGrandi dissertation, now published in WRR, where we look at how transit time affects the concentration and the quality of DOC in the streamflow.
The time that water spends to travel across the catchment isn’t just a driver of DOC concentration, but it also shapes its quality and reactivity in a low-order alpine stream. doi.org/10.1029/2024WR039392 @enricobertuzzo

If you're interested in all the ways that lake ice influences ecosystems and humans, be sure to check out this manuscript! [SNL Stefon voice]] It's got everything! Winter recreation, carbon cycling, lake effect snow, and even a section on shoreline erosion.
NEW PAPER 📃- Loss of lake ice has wide-ranging environmental and societal consequences. Notable decreases in ice cover and advances in technology have spurred rapid growth in winter research on seasonally ice-covered lakes. Read the pub: doi.org/10.1126/science.adl3…

Thrilled to announce my latest work! In this study, we explored the variables that control mean transit times (MTT) and their distribution (TTD). How can transit time be used as a coherent catchment descriptor? 👇 kwnsfk27.r.eu-west-1.awstrac… #UCuenca #UCR #UTA #CDU #IAEA #JCU

Very happy to host Michail during his stay at our lab !! He is doing a terrific job at testing this DIY autosamplers for rain and river waters developed by Benjamin FIscher and himself - we'll be deploying them in our #Suyuque #Catchments soon !
Replying to @GEASanLuis
During September and October we received a visit from Michail Alexandrakis, a Master's student in Hydrology from Uppsala University, Sweden, who is supervised by Benjamin Fischer and María Poca (@merypoca), @GEASanLuis researcher. 🌎💧
