Yeah. Pine Creek Canyon and bugs. I get it. Sounds like a lovely trip, though!

Lovely part of the world. I was on top of Carol Col last September. Did you come in over Paiute or via Pine Creek?

Check out our new paper in Earth’s Future!

We mapped 78 flood events in eastern NC from 1996-2020 and found flooding (& repeat flooding) is more common than we previously thought.

Check out this amazing opportunity to work with a rising star!

4.6 Billion Years On, the Sun Is Having a Moment In the past two years, without much notice, solar power has begun to truly transform the world’s energy system.

Among all the big bad things happening on our planet, there's one Big Good Thing, the sudden, startling rise of solar energy.
It changes the power dynamic, in every sense of the word 'power.'

Me this morning reading an MS thesis from my lab. Reading good grad student work is SUCH a joy.

Example of how the Surface Water and Ocean Topography (SWOT) satellite's water surface elevation measurements can be used to record flow wave propagation over space and generate a “spatial hydrograph.”

Hydrologists! Ever heard of a Spatial Hydrograph? Our new paper in @agu.org GRL shows that the SWOT satellite can capture spatial flow waves propagating down rivers—something previously only only observable at river gauges: doi.org/10.1029/2024...

Few support punitive funding cuts to colleges and universities - AP-NORC Most of the public believes that colleges and universities make significant contributions to scientific and technological advancement and think their federal research funding should be maintained.

The American public is broadly supportive of maintaining federal science and medical research funding, and against punishing universities by taking their funding away, according to a new poll:

Scientific figuring with three panels. Left panel shows a map of the Everglades in Florida overlaid with data from the SWOT mission. It shows very detailed water level data throughout the everglades. The second panel, in the upper right, is a scatterplot showing in situ gauge water level against SWOT water level. It shows a mean absolute error of 6.7 cm, a correlation coefficient of 0.996, and a mean bias of 6.8 cm. The third figure, a scatterplot in the lower right, shows that by averaging 30 or more SWOT pixels, high accuracy is possible.

Are water levels in wetlands important to you? @kica22.bsky.social's new paper in GRL shows that the SWOT satellite can measure water surface elevations in the Everglades with a mean absolute error of 6.7 cm. Check it out! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🚨🚨Calling all North Carolina voters!! Here is a list of every voter that Jefferson Griffin is trying to disenfranchise, please if you are a NC voter check to see if your name is on here, you have 15 days to cure your ballot to make sure your vote counts. thegriffinlist.com/assets/griff...

This dataset doesn't distinguish. But there is work on the topic! This paper defines a pond as small (<5 ha), shallow (<5 m depth), and with <30% emergent vegetation.

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....

This is effectively what led to the 1900 Galveston Hurricane being the most deadly storm in U.S. history.

We are so back, i guess. 😩

Converge freshwater science series! Joining freshwater scientists from across the triangle area to discuss ideas in a safe, collegial atmosphere monthly. Thank you NCSU for hosting the January meeting! And thank you to @ardonlab.bsky.social and other presenters for leading discussions.

So wish I could have been there. Stupid COVID!

I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely.

Advancing the science of headwater streamflow for global water protection - Nature Water Despite their substantial contributions to watershed resilience, headwater streams are becoming increasingly imperilled. This Perspective summarizes the status of headwater streamflow information and ...

Interested in headwater streams? Headwaters make up 77% of global river networks, but have fewer gauges, less accurate models and lesser protections than large rivers. See our review led by @goldenwater.bsky.social at www.nature.com/articles/s44...

And this one is on how we talk about and frame some climate concepts to wider audiences (including scientists).
Interesting looking read.

Do you do #remotesensing of aquatic environments, but you want aquatic surface reflectance data. Well, we processed the entire #Sentinel2 record for #AQUATIC surface reflectance in the Contiguous US. You can now access those data from Amazon Web Services for FREE! registry.opendata.aws/usgs_aqr/
