Interactive Learning in Hydrological Modelling With a Web‐Based Tool We introduce a web-based tool to explore hydrological modeling in classrooms. The app can be run in any internet browser on a variety of devices. The app and code are available for free. We include m...

Teach hydro modeling? Want to introduce modeling in an intro class?

Check out this web-app, activities, and code (in case you want to spin off your own)..

Thanks @jansei.bsky.social for working with me on this, which was inspired by his HBV-lite teaching software!

NSF slashes number of ‘rotators’ and well-paid managers as part of restructuring Smaller future budgets will require fewer people, NSF official tells staff

1. After getting some further insight into changes at NSF (thanks to those who reached out), I deleted a previous post where I tried to make sense of Cheatham's memo as reported in the Science story below.

Carbon Emissions From Low‐Order Streams in a Tropical, High‐Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology Patterns of pCO2 and CO2 emissions in tropical, páramo streams are consistent and predictable Dense drainage networks compensate for narrow widths of small streams resulting in similar CO2 emissi...

Kriddie, after defending over a week ago, has a new paper out in WRR: "Carbon Emissions From Low-Order Streams in a Tropical, High-Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology". Check it out! agupubs.onlinelibrary.wiley.com/doi/full/10....

The spring flood as the snow melts is the most characteristic part of northern hydrology, but this year there will be no spring flood. We will be back to the data in a few weeks, but I have never seen this before

Today was the first field day in my ERC ARIMETH project! I installed a oxygen and water level sensor in Krycklan. It was a great field day, wearing t-shirt, sunny... But this is so wrong. Mid-april in northern Sweden means a thick snow cover, but this has been an abnormally warm and dry winter.

I had the pleasure to follow along Kriddie's PhD from the distance, and her work on carbon cycling in high altitude tropical streams. Now she's Dr. Kriddie!

Looking the get the most out of your stream CO2 data?

Check out the coupled O2-CO2 model developed by Jake Diamond and me, out today in JGRB!

The model extends the single-station O2 model by coupling DIC mass balance and carbonate buffering.

Can we develop a global #deeplearning #model for daily Soil CO2 efflux?

Results show
- #LSTM models can use existing data to generate synthetic data for temperate mesic regions
- challenges of transferring relationships learned from data-rich to data-poor sites

Causal Inference With Observational Data and Unobserved Confounding Variables As ecology tackles progressively larger problems, we are moving beyond the scales at which randomised controlled experiments are feasible. Using observational data for causal inference raises the pro...

OK, #causalinference #ecology folk - my paper with the even excellent @lauradee.bsky.social on causal inference with observational data is now out in Ecology Letters! 🌍🧪🌊

Map of global lake distribution, colored by the number of SWOT overpasses per 21 day cycle. There are many lakes with a high number of SWOT overpasses at high northern latitudes, but there are also tens of thousands to more than a million lakes on every continent. Lakes are graphed by latitude and longitude on the edges of the figure.

Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data. agupubs.onlinelibrary.wiley.com/doi/full/10....

"Scissor Graph" showing men overtaking women in proportional representation in sciences after doctorate

Happy International Women's Day! Despite the efforts, while much more women enter scientific fields, due to numerous factors, few manage to remain in the field or secure senior positions. Support your coworkers, call out harmful systemic behaviour. 😘

Learning from a large-scale calibration effort of multiple lake temperature models Abstract. Process-based lake temperature models, formulated on hydrodynamic principles, are commonly used to simulate water temperature, enabling one to test different scenarios and draw conclusions a...

Your model is your hypothesis. So, why not use multiple of them? Championed by Feldbauer & Mesman, in our fresh-off-the-press paper we highlight the performance of temperature models across the globe, and discuss the path forward to get better projections!

Home - NOAA Ocean Acidification Program NOAA's Ocean Acidification Program prepares us for the impacts of ocean acidification through research and interdisciplinary partnerships.

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

Scoop: U.S. delegation pulled from key U.N. climate science meeting The IPCC meeting in China is slated to determine the content in the group's next series of reports.

‼️The US-based @ipcc.bsky.social technical support unit (TSU) for Working Group 3 Co-Chairs has been terminated, and the US won’t be attending next week’s IPCC meeting where the AR7 chapter outlines will be approved.

A friend of mine has a personal contact with Alabama representatives and will send a personal message regarding #NIH #indirect funding cuts. She is looking for personal stories of the effects of science funding cuts on individual people, particularly if they are in Alabama! Share, I'll pass them.

Position still open for applications. If computational skills are low but creativity is high, you're still encouraged to apply!

Analysis of the confined crowds at the San Fermín festival in Spain shows that dense crowds can self-organize into macroscopic chiral oscillators, coordinating the orbital motion of hundreds of individuals without external guidance, according to a paper in Nature. https://go.nature.com/3WKkb8r 🧪

EXCLUSIVE: NSF starts vetting all grants to comply with Trump’s orders Grantee accounts remain frozen, while union accuses NSF of ignoring rules governing peer review

This is not business as usual.

It’s not just a change in funding priorities going forward; it is the reneging on funding agreements and is profoundly disruptive for even those grants that will be found to be compliant.

Meanwhile, trainees who often live paycheck to paycheck are going unpaid.
