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.

We invite again the stable isotope community to present their research at our long-standing #AGU25 session on "Stable Isotopes in the Critical Zone: Methods, Applications, and Process Interpretations"

agu.confex.com/agu/agu25/pr...

The deadline is by the end of July.
Screenshot of the abstract submission page for the session at #AGU25 "Stable Isotopes in the Critical Zone: Methods, Applications, and Process Interpretations"
Abstract text: " Natural abundance and enriched stable isotopes are exceptional tracers, contributing to a deeper comprehension of the transport and transformation of water, carbon, and other elements. Their use has led to novel insights into the Critical Zone and the soil-plant-atmosphere continuum. Furthermore, new methodological and technological developments have facilitated using stable isotopes to trace system exchanges and feedback processes on many levels, from micro- to regional-scales. With such advancements, new opportunities and perspectives have arisen, fostering increasingly interdisciplinary approaches to Critical Zone processes. This session aims to bridge bio-hydro-geo-eco communities by showcasing studies that use stable isotopes to enhance our understanding of the Critical Zone and/or to advance relevant stable-isotope methods and application techniques. We particularly welcome studies that transcend disciplinary boundaries and adopt innovative approaches to improve process understanding. Additionally, this session encourages presentations of opinions, perspectives, and syntheses that guide the Critical Zone stable isotope community."

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!

This week in writing about teaching: Over the next several weeks, I'm going to explore how I handle teaching students to code in classes that aren't just about coding.

This week: Why live code?

Live coding: what is it and why you might want to try it.
Fun, scary, and it works!

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!

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.

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' 😃
