Flood waves like those that devastated Texas last week can be seen by the NASA #SWOT satellite. Another reason to support #NASA Earth Science

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

Delighted to see our @NERCscience @EvoFlood project research on changing flood hazard and risk profiled by @theAGU 💜 @lborouniversity eos.org/research-spo...

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:

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/...

Congrats to Luisana Rodriguez Sequeira, who successfully defended her Master's Thesis on satellite #remotesensing of #microplastics in rivers! I had the pleasure of co-advising with Dr. Austin Gray @austindoug13.bsky.social. She presented to a standing-room-only crowd—well done, Luisana!

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....

What a fun paper describing rivers in North and South America that flow into multiple drainage basins. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Excited for the annual Virginia Tech Geoscience Student Research Symposium (GSRS) — a 2-day event w/ talks, poster sessions, the always-entertaining 'UpGoer Five' session, and more! It kicks off this morning and I'm looking forward to learning about all the amazing science our students are doing.

Our new paper maps wind fields over lakes using radar backscatter from SWOT and Sentinel-1 satellites. This technique achieves a much higher spatial resolution than what is available from atmosphere reanalysis products: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

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...

We are alarmed by the Administration’s actions to freeze science funding and eliminate DEI efforts and climate change initiatives, which go against AGU’s mission and harms our members. We must unite to address these changes, beginning by hearing from you. Read more: https://buff.ly/4hm8r4e

New US administration ditches Biden's plan to limit levels of PFAS manufacturers can discharge into rivers from their waste pipes. Numerous studies have linked PFAS to cancers, liver, thyroid, kidney conditions, fertility issues & harm to fetal development 🧵 www.ewg.org/news-insight...

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...

❗One week away before Abstract submission deadline for #EGU25. ➡️Consider session HS10.5 where we invite all contributions aiming at bridging limnology and hydrology together to better connect lakes and reservoirs to their catchments 💧🧪💻 meetingorganizer.copernicus.org/EGU25/sessio...

New paper by Dongmei Feng finds an interesting pattern in global streamflow trends through time: increasing streamflow in upstream river reaches and decreasing flow in downstream reaches: www.science.org/doi/full/10....

See you when I’m 75!

Cool paper alert: Yu et al. used SWOT satellite observations of the ocean's surface height to create a global seafloor map at 8-km resolution: about twice the spatial resolution of previous global maps! science.org/doi/full/10....

The Global Rivers Group is well represented this week at #AGU. Seven current members and three alums here in DC. #AGU24

I am soon recruiting two PhDs and a postdoc, to work on carbon, methane, metabolism in arctic stream networks. Glad to chat potential opportunities during #AGU24 @agu.org ! There is also soon another postdoc position on oxygen responses to peatland restoration with @ryansponseller.bsky.social ⬇️

Same thing is happening in the field of flood forecasting

“There are just two major pacts governing nuclear weapons in the cosmos, both of which predate Neil Armstrong’s first steps on the moon,” W.J. Hennigan writes. Decades later, are they enough to protect against a new space Cold War? nyti.ms/4imfWsG
