A Data‐Driven Simplified Nernst Equation for Estimating Reduction Potentials in Groundwater from pH and Temperature Reduction potentials of redox couples are fundamental for understanding subsurface geochemistry and guiding water resource exploration and management. Reduction potentials are routinely calculated wi...

Kind of like entertainment news such as Fox and CNN has been bad for news

Motherfucking wind farms…

“Staggering” Water Loss Driven by Groundwater Mining Poses Global Threat A new study finds that freshwater resources are rapidly disappearing, creating arid “mega” regions and causing sea levels to rise.

Important findings related to groundwater depletion and also some great sci art!

Our first black swallowtail butterfly of summer emerged this morning! Several more on the way soon.

Thank you for putting it together!

Groundwater raining down on the High Plains

Solar well and water tank for livestock. Old windmill in the distance.

Student recording data in front of a livestock pen

Student sampling a domestic water well

Groundwater sampling in south-central Kansas this week. Nearly half of the wells we have sampled in this part of the High Plains Aquifer have high nitrate levels.

Yes, and if not, we can count on him to do/say something else outrageous to change the conversation soon.

Hydrology Paper of the Day @danielepenna.bsky.social on how preferential flow in a Mediterranean catchment is affected by antecedent soil moisture and soil properties: random forest models for classification of hydrological responses and preferential flow event identification from soil moisture.

Coal seem along a creek

Stream meander

Took a walk down memory lane and visited the woods I played as a kid in central Illinois. It’s a steep little valley cutting through Pennsylvanian cyclothems. Lots of stinky mud and springs. I suspect this place helped set me on my path to become a geoscientist.

End of semester gift from a couple of students :)

Hydrology Paper of the Day @agu.org on how topography is related to hydrology: a historical perspective; climate, precipitation, energy fluxes and exchange in the atmospheric boundary layer; biogeochemical cycles and vegetation; topography, gradients, and groundwater; and future research directions.

It sounds like we agree on quite a lot. The current situation here in the US boggles the mind.

No worries whatsoever! Words mean different things to different people and meaning changes with time. Do not complicated at all 🤣

Yes, absolutely it can. Perhaps you’re thinking of basement?

It is really beautiful. Not something I appreciated before moving here

The bedrock here in the Flint Hills consists of alternating layers of limestone and mudrock, which leads to lots of little waterfalls and springs dotting the landscape.

This aside, however, I talked to a rotator this week and I want to convey that it's essential that you – the PI – keep doing your science; including writing and submitting proposals (whatever that looks like). This is a case where doing your job competently is actual resistance...

🔊 Listen Now: Less lawn, more wildlife! Here’s how to ditch turf for native plants Up From Dust from KCUR 89.3 on NPR One | 24:20

Yes please - Less lawn, more wildlife! Here’s how to ditch turf for native plants:

Thanks for pointing that out. It looks like one key difference is whether the model consider unsaturated conditions. Topodrive is all saturated zone.

Limestone outcrop ledge along a large lake

The local crappie population was completely unharmed but I did get a nice view this weekend of Permian limestone along Tuttle Creek Reservoir just outside of Manhattan, Kansas.

White House budget fact sheet, proposing unprecedented cuts to programs related to international aid, research, education, health, human services, labor, commerce, small businesses, and more, while dramatically increasing the budget for defense and homeland security.

They're dismantling (what remains of) the social safety net and replacing it with a dragnet instead.

TopoDrive has become an indispensable online tool for me as I teach Hydrogeology. If you're unfamiliar, check it out here: tdpfonline.net. I caution you, however, that you'll want to play with it for more time than you have available.

Greenhorn limestone with scorpion

Clams in the greenhorn limestone. This unit was traditionally used to make fence posts since trees are sparse on the prairie.

Got a chance to look at some nice Cretaceous outcrops in central Kansas with wife and kiddos and we even saw our first local scorpion. Might need to be more careful when flipping over rocks :)

#WithoutNSF I wouldn’t be a scientist.
- I got in an NSF REU Program and learned about grad school.
- I did my PhD funded by 2 different NSF grants.
- As a postdoc, I was an NSF RCN participant, building my network.
- I got tenure with an NSF RAPID grant.
- I got promoted with an NSF EPSCoR grant.
