The Current State of Undergraduate Hydrology Courses in North America: A Path Forward Examined syllabi for introductory courses in hydrology The titles, topics, and approaches to assessment varied widely across courses Found limited consensus in how hydrology courses are taught a...

@hydrochrista.bsky.social @domciruzzi.bsky.social, and I asked hydrologists across the country for their syllabi so we could investigate how instructors were teaching hydrology courses and think about the future...

Looking forward to talking non-perennial streams with MZ tomorrow! She'll do an overview of all of the great synthesis work in the NPS literature in the last ~5 years, and I'll do a deep dive on the organization of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project! Join us!

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!

Recently, all the AAAS Science & Tech Policy Fellows at EPA were terminated from our positions with little notice and for no clear reason. This effectively ended a partnership that had been going since 1980 and which had brought hundreds of scientists to the EPA as fellows, many of whom stayed. 1/7

Latest paper out of the WS hydrology lab! Here we show spatial variability in lithology is important for streamflow behavior and carbon export, but geogenic solute export behavior is similar. agupubs.onlinelibrary.wiley.com/doi/full/10....

National Science Foundation fires roughly 10% of its workforce NSF fired 168 employees, leaving the agency less equipped to fund a wide range of scientific research.

Yesterday was the darkest day of my professional life so far. Many of NSF’s best and brightest people fired indiscriminately. The terms of their firing cruel. My colleagues matter, they are valued and they make a difference. I have no words. www.npr.org/2025/02/18/n...
