Next was PhD student Michael Hasson, giving an invited talk about how #vegetation has changed the way #rivers move through space, with implications for interpretations of river deposits through the first 90% of #Earth history (12/16 pm, EP24C-04). Published in @science.org this year.

is it just me or the @jgrearthsurface.bsky.social websystem has a problem? Like, I log in, and if I try to either submit a manuscript or accesso my live manuscripts, I am sent back to the login page again....

Here is a hastily constructed animated gif from different NASA satellites showing the progression of the Hayli Gubbi eruption. Note the tall ash plume spreading NE (right) and a lower, light tan ash flow(?) moving NNW. #eruption #volcano

Rethinking point-bar architecture: Insights from the meandering Powder River (Montana, USA)—Read the new study in #GSABulletin: geosociety.co/4nUzJBa#GSABulletin #FluvialGeomorphology #Sedimentology #Rivers #PowderRiver Photo by USFWS

For anyone interested in stochastic dynamics, nonequilibrium/critical phenomena, Langevin equations, etc, I *strongly* recommend these new lectures (40x 40 min) by Erwin Frey (LMU Munich). Outstanding. 🧪🧮 www.youtube.com/playlist?lis...

The last piece of work from Riccardo Maitan's PhD project is finally out in @geosociety.bsky.social GSA Bullettin "Discharge variability drives point-bar macroform degradation in the meandering Powder River (Montana, USA)" Read more here: doi.org/10.1130/B383...

Findings from a recent study could upend the conventional view of how rivers have shaped continents over time. It’s “a significant revision to our understanding of the history of the Earth,” said lead author Michael Hasson. @marslogander.bsky.social

Did you know that sand records its transport history as it moves across Earth's surface? We developed a new tool to investigate billion-year-old rocks by looking at microscopic features on zircon sand grains. Check out our new paper in @geosociety.bsky.social to see how! doi.org/10.1130/G537...

Just out: PhD candidate @mcolinmarvin.bsky.social shows that like in quartz, #zircon grains preserve microscopic archives of their transport history. But unlike in quartz, those archives remain decipherable for billions of years, unlocking first 90% of #Earth ’s history @stanforddoerr.bsky.social

The DEM is much less exciting.

Can you tell where this fascinating landscape is? Sentinel1 GRD synthetic aperture radar, seasonal change using VV polarization, descending. In theory, related to a lot of news these days, especially the faintly visible ESE to WNW line in the northern part.

🌊 A wednesday full of science @ #RCEM2025 From fascinating talks on coasts, rivers & estuaries to the second poster session, has been packed with insights and exchange. 💡🖼️ 👏 Thanks to all presenters for pushing the boundaries of our field—discussion & collaboration are thriving!

🌅 Final day begins @ #RCEM2025 We’re kicking it off with the keynote of Dr. Zheng 🎤 —bringing fresh perspectives on biomorphodynamics. It’s being an incredible week of talks, posters & community—let’s make this last day just as inspiring! 💡🌊 #RCEM2025 #Keynote #CoastalScience

So proud of Michael!! 😎 This work was a collaboration with @alvitello.bsky.social at @unipd.bsky.social and A. Ielpi and @ubcokanagan.bsky.social Check also: - Perspective by J. Pizzuto: doi.org/10.1126/scie... - Stanford’s press release: sustainability.stanford.edu/news/rise-pl...

Plants change how river bends move - paper by PhD student Michael Hasson out as First Release in #Science!! Paper: doi.org/10.1126/scie... Before #plants, #meanders did not grow laterally as much but translated downstream, making them look like braided rivers in rocks. @stanforddoerr.bsky.social

Showed this slide in class and it didn't elicit a single giggle or guffaw. Something's up.

Erin is truly an extraordinary hurricane, one of the biggest and most powerful we've seen in this part of the Atlantic. Mercifully, it'll spare the U.S. an otherwise extensive and devastating blow, but we won't escape major coastal problems. My very latest ⬇️

Elements of a landscape, the Netherlands. Where rivers once slowly meandered through lowland peat bogs, straight lines now cross them out. This is the Angstel river, between Loenen aan de Vecht and Baambrugge, the Netherlands. On the right the Vecht river.

It gave a young PhD student the greatest pleasure to be able to publish in the first volume of Earth Surface Processes. Our paper showed how hydraulic conductivity in frozen soils declines below 0 °C. The paper still gets cited regularly! #ESPLMemoriesAt50 - Prof. Tim Burt, Durham University

Interesting pic of Woodhead Reservoir (A628 Woodhead pass from Manc on left) showing a mix of former valley floor, sedimentation, re-working and mixing of what looks like AMD red from the left and clearer water from the top.

Had an amazing time at #LPS25 this week, where @esaearth.esa.int unveiled the first images from the Biomass satellite. Read our story with @esmestallard.bsky.social and see the stunning new images for yourself:

A nice river, somewhere, meandering through a bit of glacial deposits and cutting into Upper Cretaceous shale and sandstone. High-resolution prints are for sale on request (special edition!).

More river fun, unrelated.

Please take my money, thank you.

It doesn't get reiterated enough that "human on a bicycle" is not only the most efficient way that a person can move, it's the most efficient form of motion ***ever observed in land animals***.

@channelwidth.bsky.social It’s raining here where I live and I am pretty sure that’s no casual based on what happened last night!

🚨New Paper🚨 @rockiceandsnow.bsky.social and others (including myself) quantify the evolution of North America's deepest canyon (sorry, Grand Canyon, it's not you).

There are very few images of the Earth surface that fascinate me more than the flooded dunes of Lake Chad (Sentinel 2)

Let’s be clear: the reason why cranky things like www.a-techo.org exist is because #academia has somehow painted itself into a corner by fetishising: 1) papers as the currency of *excellence*; and not only that, but also; 2) the *volume* of papers published by an individual 😭

The use of color in scientific visualization is steadily improving, but I still see variants of the rainbow palette more often than I’d like. For more info, and recommendations on for good color palettes, read my series “Subtleties of Color“: earthobservatory.nasa.gov/blogs/elegan...

Any geoscience/hydrology-oriented scientific illustrators out there? I have funding to help me build water resources educational content for the citizens of New Mexico! DM me if interested!
