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.

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...

#SWOT #hydrology #RemoteSensing #EarthObservation

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.”

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:

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.

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/...

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.

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.

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....

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.

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.
