The DEM is much less exciting.

A stark-looking satellite image, mostly gray to dark red and black. On the west side are many fresh-looking cinder cones and lava flows. On the east side, desert mountain ranges with alluvial fans around them. There is a dry river bed crossing the southeast part of the image.

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! 💡🌊

A series of graphs that show relationships between variables such as the divorce rate in Maine and the per capita consumption of margarine. The words "correlation does not equal causation" are written on the slide.

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

Enormous Erin Growing Larger: Violent Seas, Dangerous Waves, and Treacherous Surf Expected Along the U.S. East Coast Tropical storm conditions and coastal flooding will begin affecting North Carolina’s Outer Banks by this evening

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

Beneath the canopy: Pioneering satellite reveals rainforests' hidden worlds - BBC News First groundbreaking images from the Biomass satellite could change our understanding of rainforests

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:

Digital elevation model of the Grand River, South Dakota, USA. River floodplain in blue (high) to white (low), the rest of the landscape in orange (high) to green (low). The river meanders, the landscape on both sides of the floodplain is eroded with finger-like gullies.

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***.
