Kicking off this 75th anniversary, Dianne McKnight gave a very fun keynote! how the work on DOM in small streams makes a difference: definitely through outreach.

Our Institute of Arctic and Alpine Research @instaar celebrates its 75th anniversary this year! Josie Arcuri was one of the graduate students showcasing how the Arctic system is changing. Well done!

That does sound really frustrating!!! Hoping for the best from here.

Hopefully resolved? Never great to have to go to ER.

Plugged our cool paper, but also Ethan Pierce's code for modeling ice-rafted debris is available on github, not yet fully integrated in landlab because of some dependencies, but vote it up, and we can talk to the @csdms.bsky.social software engineers!

US-Greenland science partnerships are on thin ice CU Boulder researcher Twila Moon shares what is at stake as President Trump bids for Greenland.

“The Greenlanders have been very generous in sharing information with us and providing resources to us. We would like to see this peaceful collaborative relationship continue.”

Sediment transport by Greenland’s icebergs - Nature Communications Greenland’s icebergs transport 450 megatonnes of sediment to its fjords each year, representing one-third of the ice sheet’s total sediment export. This ice-rafted debris builds shoals at tidewater gl...

Still really dry in Colorado. Current snow pack in the Colorado Headwaters, the black line, is 57% of 30y reference. Gonna try to ski this weekend, we'll see.

Missed this thing even if I care about sand. But love the zoom-out and thinking about the fundamental part of science; to be willing to be wrong, to be willing to listen to conflicting evidence.

Will be interesting! Sending this call out to the US Community Surface Dynamics Modeling community too.

Earth twin needs geoscience - GEOSCIENTIST As society turns to Earth Digital Twins for decision-making, geoscience must play a defining role, urges Pankaj Mishra.

Lithosphere sure, yes! But earth twins should also be scalable - to make them relevant for local hazards we need to move water and sediment around and allow for a changing earth surface geoscientist.online/sections/vie...

Crazy idea: an aircraft carrier iceberg that floats around in the Atlantic Ocean, so that no-one would need to built bases on other people's territory. Would that be possible? Oh, guess what we are reading in Geomorph seminar? doi.org/10.3189/S002...

As sea ice retreats, waves matter more. Models show wave events resuspend sediment on the Beaufort Sea shelf, reversing net transport westward despite eastward currents. This affects coastal change & carbon fate in the Arctic. Read more: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Allows for easy coupling between a process model and GeoTiff data, can come in handy!

‘Yankee, Go Home’: Greenlanders Protest Trump’s Takeover Plans

It was raining on this protest in Nuuk. Temperatures in Greenland have been absurdly warm recently. THAT is what we should be talking about.

Prairie dog numbers fall on Boulder open space as city continues lethal control City will continue to use lethal control methods and maintain a pilot program that helps landowners pay for barriers.

Will be an interesting read! This event devastated downstream La Bérarde, a small community that was built on the alluvial fan many centuries ago. Launch point for some famous alpine climbs in Les Écrins.

Prairie around us is so wind-scoured after the storm events of this early winter. It's been dry since October and this is an area with a large prairie-dog colony - so more sparsely rooted and vegetated. I estimate we lost several cm's of topsoil.

Hundreds of Scientists “Vehemently Oppose” U.S. Effort to Purchase Greenland - Eos About 350 scientists scientists have signed a letter condemning U.S. President Donald Trump’s efforts to acquire Greenland.

“President Trump’s talk of ‘buying’ Greenland is not only an affront to Greenland’s autonomy but also a dangerous distraction from the urgent work of addressing environmental change impacts to US citizens,” the letter reads. eos.org/research-and...
