It is that time! Field prep at its best. Go team.

Why are the Rockies rocky? New work from Matt Rossi and friends -

Agreed! Brian Yanites at @csdms.bsky.social meeting today!

Leaving a rainy Denver, FINALLLY! to @csdms.bsky.social meeting in Minnesota.

Happy to say that Dr. Josie Arcuri successfully defended her PhD Thesis yesterday. Thesis is not called "River Ice Matters" - but that is what her research revolved around. Josie picked up some field skills on the way, but hydraulic and morphodynamic river modeling is her jam. Huge congrats!

🟣 As part of our new series on Artificial Intelligence in research software, we have published a new guide: Getting Started with ML and AI in Research Software, written by Paul J. Wright. Find out more about the guide and how to access it at www.software.ac.uk/news/new-gui...

@natgeosci.nature.com editorial highlights how a sweep of recent studies are showing the profound effects of humans on rivers; including the effect of climate change on Arctic systems (our paper!). @geolidf.bsky.social @colorado.edu www.nature.com/articles/s41...

Ahh, we will check it out, with special interest for the Juneau Icefield! @app-glaciers.bsky.social

Supercool footage of the enormous scar! Landslide in Alaska Set Off a Tsunami. There May Be More to Come. www.nytimes.com/2026/05/06/s...

Your voice matters in planning future community efforts, modeling infrastructure and plans for training. Let CSDMS know ..... The survey should not take too long to fill out (8-10 mins).

Scaling relationship in the inverse, an long known patterns in natural river systems works in reverse in delta distributary channels - shall we cast it as Dong's law? Very nice work Tian and @lvulis.bsky.social and co-authors. www.science.org/doi/10.1126/...

Wow Eric, Doug and @jakegearon.bsky.social I love this paper on levees! There is soo much to learn on river sedimentatry processes from analyzing continental scale digital elevation data. @csdms.bsky.social and @opentopography.org agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Melting glaciers along Greenland’s coastline are affecting how the ocean breathes and how it reacts to and buffers itself against change, writes @henrychenson.bsky.social of @au.dk. eos.org/science-upda...

Congrats to Shang Tian and Dongfeng Li, our paper on Arctic river sediment it out today! We highlight how small Arctic rivers have increased sediment and changed disproportionally faster (over the satellite record). New machine-learning approach on landsat data. www.nature.com/articles/s41...

Absolutely fascinating article by @trinamoyles.bsky.social in @cangeo.bsky.social about how declines in dall sheep in southwest Yukon might be (partly) related to increased levels of wind-blown dust following diversion of Ä’äy Chù (Slims River). 🧪⚒️🐏 @carmtree.bsky.social @draeolus.bsky.social

Showing Spruce Gulch Wildlife and Research Preserve activities and to visiting CU alumni. I marched everyone through the scars of the 2013 Boulder flood, incised debris flow gullies and toppled mega boulders. Tim and Kat had the pretty wildflowers. @colorado.edu

@nicolegasparini.bsky.social , @mdpiper.bsky.social and @geolatinas.bsky.social look at this! Coco!

Awesome Nicole!

Thousands rally in #Boulder against Trump as “No Kings” protests sweep the country, drawing millions to more than 3,000 events nationwide. boulderreportinglab.org/2026/03/28/t...

Having difficulty keeping up with all the interesting papers this week, this is one of them! Need summer break to come faster.

Join us in MN!

Congrats to Dr Brianna Undzis and her advisor Prof Julia Moriarty! One highlight: ROMS modeling of the Beaufort Sea shelf shows that in summer, sediment wafting around is likely due to wave resuspension. @csdms.bsky.social

Whaaaaat, that much?

The Soilgrids data component get used a lot! Maybe because of the handy example notebook?

The Topography Data Component fetches land elevation data from OpenTopography and loads it into an Xarray DataArray. Learn more about the Topography Data Component at github.com/csdms/bmi-to....

I'd like to do a series of posts this week to highlight CSDMS Data Components. Data Components are software that help connect data sources to numerical models. For more information on the idea behind Data Components and their implementation, see Gan et al. 2024: doi.org/10.5194/gmd-....

Eye candy for world glacier day- a flight back south along the Canadian side, Kluane Park, had me glued to the window. Maybe I will get to go there one day!

Heatwave appropriate field class elements: how far downstream do mass wasting events travel. In our case, into the South Platte. We found it. @colorado.edu

Collected survey data with drone in Spruce Gulch-Kevin Rozmiarek showed our class what survey design involves, and how to process data. Big thanks! @instaar.bsky.social

The authors of a Comment article in Nature highlight concerns over adopting AI in meteorology and call on the weather and climate community to set clear standards, starting with agreed data sets, for testing out-of-sample extreme-event predictions objectively. 🧪

Doing geomorphology all day, in the best debris flow gullies in my humble opinion. But then students do get REALLY excited about pegmatites, elk vertebrae, xenoliths and fault evidence in rocks. This rock specimen got carried for a 25 min hike. @cubouldearth.bsky.social

Tinkering before fieldwork, improving mounts for river and lake instruments. @cubouldearth.bsky.social CRYSP lab was busy this weekend! @instaar.bsky.social

Even did some of our university field classes on our bikes!

Online in about 2 weeks, registering is still possible.

OMG, this is not good news. Not too much fuel left in the area. What about Spruce Gulch though?

Ahh good to see! This will be cool to put our work at Gilkey and Field glacier lakes in context. @app-glaciers.bsky.social

Friday afternoon field class time, working out differences between handheld GPS units and phone GPS (while on airplane mode). @cubouldearth.bsky.social

A new paper by Ogden et al. describes the framework of the NextGen Water Resources Modeling Framework, which uses CSDMS technologies such as the Basic Model Interface (BMI). onlinelibrary.wiley.com/doi/10.1111/...

Check this out, another model intercomparison experiment is launched, with very cool tools and coastal wave forcing data ready to grab for download. Challenging all beach modelers.

This is a great post to get an idea how a skilled user quickly do science by prompting. www.theclimatebrink.com/p/the-ai-aug...

Congratulations to Keith Musselman and Irina Overeem, who were selected as members of the inaugural cohort of Sustainability Research Initiative Research Fellows at CU Boulder. As fellows, the researchers will participate in a year-long interdisciplinary research incubator.

Antartica may be far away, but sea level rise originating from the decay of its mighty icecap is relevant for millions to billions of people. F.e. www.nature.com/articles/s41...

Helpful article for understanding what is at stake for different states using Colorado river water - hydropower, municipal use and irrigation downstream, but also irrigation versus ecosystem health in the Upper Colorado states. Dams not designed for this drought. www.landdesk.org/p/the-colora...

Fresh off the press, an amazing application by Beatriz Boggiani of landscape evolution modeling of the Permian redbeds and copper occurrence. Uses paleo-topography and climate to create a source to sink reconstruction of a continental scale basin. agupubs.onlinelibrary.wiley.com/doi/full/10....

Bedrock characteristics matter for glacial incision, super nice model-data demonstration by Div Patel and @rachelglade.bsky.social for the iconic Finger Lakes in NY. journals.psu.edu/geomorphica/...

📚 What we're reading: "Working With Non-Cloud-Optimized Data Just Got Easier," on Earthdata. NASA’s Openscapes and earthaccess communities collaborated to bring cloud-like capability to popular, non-cloud formats like netCDF/HDF files found in NASA's Earthdata archive. 🌐 #opendata #nasadata

I would not be a scientist here if this sort of regulation had been around. In STEM many graduates and postdoc are international.

Meanwhile on earth ....

Crew 12 off to the space station. EU-Russian-US collaboration, led by Jessica Meir! Women in science and space this week - amazing things are still happening. www.npr.org/2026/02/13/n...
