O Levee, Where Art Thou? Measuring the Abundance of Natural River Levees Across the Contiguous USA All else being equal, natural levees tend to form on gently sloping rivers and rivers that migrate quickly River discharge is a poor predictor of natural levee abundance Natural levees occur on ...

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 Make the Coastal Ocean More Sensitive - Eos Fresh water from retreating ice does more than raise sea levels. It affects how the ocean responds to acidification and other environmental changes.

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.

Synergistic Integration of Flood Inundation Modeling Methods - Eos Recent flood modeling advances are trending into silos that compete rather than complement each other, hampering the opportunity for transformative progress toward protecting lives and communities.

Yes, it is a puzzle of factors. We found yedoma regions and the far northern basins in continious permafrost, with more prevalent younger thaw slumps, see faster increases in SSC.
There is an illustration of these correlations in the Supplementary material.

I dreamed up my own cover for it.

Increasing river sediment concentration and flux across the pan-Arctic - Nature Geoscience The total sediment flux from land to the ocean across the pan-Arctic has risen by 15% since 1980, driven by greater river discharge, intensified thermokarst disturbances and wildfire activity, accordi...

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...

Wow, i did not know about this!

Because with struggle comes flow, and satifaction after the struggle!

Born for this: unravelling the disappearance of Dall sheep When scientists started documenting alarming declines in the Thechàl Dhâl herd of Dall sheep, it sparked a vital conversation between biologists and First Nations communities. What was causing the dro...

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). 🧪⚒️🐏

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.

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

When chicks fledge, word is spread to show respect for the closure helped!

Ok a bit different, but in our area peregrin falcons and golden eagles nest in on climbing cliffs. The land managers work together with the climbing community to watch for nesting behavior, and post closures for cliffs. Maybe something for the CAF to take up?

Awesome Nicole!

Thousands rally in Boulder against Trump in latest 'No Kings' protest Drummers, singers and thousands of marchers filled downtown Boulder in the latest wave of anti-Trump demonstrations.

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!

Just looked at the paper in more detail - very nicely done, what a fun imaginative project, I love that I will ever after look at it as the swaying Devils tower.

Cool nevertheless! You certainly grabbed my attention with the animation!

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?

CSDMS Data Components: data–model integration tools for Earth surface processes modeling Abstract. Progress in better understanding and modeling Earth surface systems requires an ongoing integration of data and numerical models. Advances are currently hampered by technical barriers that i...

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!

The mount worked great!

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

I knew the NSF budget, but to see all of these agencies’ budgets in comparison with the request is miserable. This should not go through.

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

Can AI models reliably forecast extreme weather events? More-rigorous testing is required before artificial-intelligence approaches are widely adopted by public forecasting agencies.

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. 🧪
