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

Footage of the aftermath of the earthquake in Severo-Kurilsk is published by the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences

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.

The global response of deltas to river sediment supply changes is 6 years. Cool new delta paper in @nature.com Communications, led by postdoc Jie Wang! open access link here: www.nature.com/articles/s41...

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.

Landsat 7 received its fina commands yesterday, ending a 25-year long mission of discovery. 🧪🛰️ www.usgs.gov/landsat-miss...

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 😭

It's one of those muddy days in the field! (stepping inside an abandoned and partially infilled tidal channel)

Going through photos from our March trip to Southern Utah, as part of an effort to distract myself from current events. Cross bedding and deformed / liquefied cross bedding in the Navajo Sandstone. Tim Lawton for scale ⚒️🧪

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!

We are very excited to now have a platform on Bluesky to connect with our fellow students, researchers, and staff!! 🧑‍🔬🌎🦦

The talk by @sineadlyster.bsky.social is uploaded to youtube! The impact of vegetation on delta landscapes and stratigraphy: Insights from physical experiments 🌱🌱🌱 🟨🟨🟨🟦🟦 🟨🟨🟨🟨🟦 youtu.be/1xGKVL-2HMc

Had a great time at the #sandpiper toolchain launch workshop, with bonus of being back visiting the St. Anthony Falls Laboratory ~9yrs since when I worked there!

Yesterday I got a tour of the eXperimental Earth Scape facility, also known as Jurassic Tank, at St. Anthony Falls Laboratory. Even though the tank has not been used since 2015, a lot of the data from it is available and it is an important piece in the history of sedimentary geoscience

Work led by Alice Puppin shows that tidal-channel abandonment (due to stream captures or meander cutoff) leads to rapid C accumulation. "Rapid Infill of Abandoned Tidal Channels Creates Hotspots for Blue-Carbon Accumulation in Coastal Wetlands" agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Was an absolute pleasure to be @unipd.bsky.social Dipt di Geoscienze last week with @alvitello.bsky.social & others. A hat-trick of seminars (with special thanks to the admin team for advert), lots of time set aside for head-scratching at the board, and delicious food at every turn. The 🤌 best 🤌.

I knew that the protective walls they built around Grindavík to protect the village from the lava were big, but I didn't realise just how huge they are. Here seen with trucks and machinery for scale. Photo by Ragnar Visage for RÚV.

Absolutely amazing video. Direct displacement of a drainage/channel: it is possible to see a right lateral displacement of the thalweg of about 1.5 to 2 m. It is also possible to see the fault plane exposed! Credit: okarun011 on TikTok

This could be bad: M7.7 shallow earthquake near Mandalay ⚒️🧪

Check out our paper in @agu.org where we provide evidence for a continuous transport pathway around Titan’s equatorial dune fields, only interrupted by the Xanadu region (with implications for the nature of Titan’s sand grains!) agupubs.onlinelibrary.wiley.com/doi/full/10....

Postdoc Carlos Alvarez shows that Mars’s large #aeolian #ripples are not impact ripples through low-pressure #wind tunnel experiments at #NASA Ames. Very excited about this one! @stanforddoerr.bsky.social www.nature.com/articles/s41...

First post on BlueSky! I'm a new Assistant Professor in Hydraulic Engineering at @epflenac.bsky.social and just launched my lab: STREEM – the Laboratory for Sustainable River Engineering, Energy, and Morphodynamics! ⚡️🌊🏞️ epfl.ch/labs/streem/ I'm hiring PhDs—check out the website for the application!

Question for our congress reps: July 2025 marks the 80th anniversary of the report that led to the founding NSF & NIH, elevating the US from scientific backwater to world leader in research & discovery. Is now the time to surrender that leadership? If not, what are you doing to prevent it?
