Our primary convener @davidguzzy.bsky.social made this nice flyer for the session. We are happy to have the @segura-lab.bsky.social joining the session as an invited speaker! You all have still 9 days to submit your abstracts on "Stable Isotopes in the Critical Zone": agu.confex.com/agu/agu25/pr...

H133 - Stable Isotopes in the Critical Zone: Methods, Applications, & Process Interpretations

Session description:
This session aims to bridge bio-hydro-geo-eco communities byshowcasing studies that usestable isotopes to enhance ourunderstanding of the CriticalZone and/or to advancerelevant stable-isotopemethods and applicationtechniques. We particularlywelcome studies thattranscend disciplinaryboundaries and adoptinnovative approaches toimprove processunderstanding.

Wrapping up your PhD? I’m planning to hire a postdoc in the next few months (start date flexible). Will start formally advertising soon, but you heard it here first!! Possible research topics include - critical zone hydrology, agricultural water quality, SW-GW interactions. Reach out if interested!

If attending @acs.org‘s #ACSSpring2025, check out Lohita’s presentation tomorrow! She will be talking about her work related to the electrosorption of organic micropollutants using activated carbon fibres.

Daily streamflow from 1984 to 2018 in approximately 2.9 million rivers globally. 👉 The numbers set the play! More flow upstream and less flow downstream. 👉 The title says it all! Incredible dataset on the hydrosphere awaiting to be crossed with biosphere data! 🧪🌐🌍 www.science.org/doi/10.1126/...

More flow upstream and less flow downstream: The changing form and function of global rivers

We mapped daily streamflow from 1984 to 2018 in approximately 2.9 million rivers to assess recent changes to global river systems. We found that river outlets were dominated by significant decreases i...

Tomorrow at #AGU24 Im talking on how & why lake trophic state might be changing nationally using Landsat, MERRA-2, MODIS, NADP, Invasive Species, and HydroLAKES, & EPA data. I might be on the stage, but this work stands on the shoulders of the observing systems tasked with collecting these data.

We had a fun "Isotopes in Critical Zone" session dinner tonight and everyone seems ready for the Thursday afternoon poster session at #AGU24. Make sure to stop by and get to know the amazing work.

Matthias Sprenger@matthiasprenger.bsky.social · 2y ago

Please also on Thursday afternoon at #AGU24 join for the poster session that features lots of different isotope applications and will provide great opportunities for a more in depth exchange.

#AGU24 take advantage of the metro system while you're in DC! My fun metro story is that back when I was working as a tech at USGS in NoVA after undergrad, I met my future spouse at a metro station on my usual commute. He says 'Ride public transit- you never know who you might meet' 😃

I’m recruiting graduate students and a postdoc to work on a range of hydrology topics- from water quality in agricultural landscapes to critical zone process (a)synchrony! Interested? Let’s chat at #AGU24!!!

Margaret Zimmer@margaretzimmer.bsky.social · 2y ago

Excited to be back at #AGU24 after a 4 year hiatus! I’m not presenting, but lab members are!! First up- check out Sam Motz’s poster Monday AM on transit time distribution modeling in non-perennial streams! Poster H11T-0957
