@think_or_swim @EliotJacobson Is there any reason to believe Antarctic sea ice follows a normal distribution?

Not to be alarmist but…this is what’s called a six-sigma event, now unfolding in Antarctica. Otherwise known as a once-in-7.5-million-year event. Hang onto your hats. HT @EliotJacobson

@ArizonaDOT Can I get on sb at 260?

*CLOSURE* I-17 southbound is closed near Camp Verde. The closure is due to a crash at milepost 291. Expect delays and seek an alternate route. There is no estimated time to reopen the highway.

@ElevatedWeather NWS is predicting much less snowfall tomorrow, why do you think that is?

NEW PAPER! Some folks and I wrote a review on modeling river deltas for the Treatise of Geomorphology vol. 2. sciencedirect.com/science/articl… If you are frustrated by the blasted paywall, DM me for a copy. @johnburnhamshaw @sedSalter @JorgeLT000 @AustinChadwick_ @NardinWilliam

Consider submitting your abstract to our AGU session! Predicting the fate of river deltas and coastal wetlands: remote sensing, numerical modeling and field advances agu.confex.com/agu/fm21/preli…

@sineadlyster @liz_hajek Data on individual threads of braided rivers: esurf.copernicus.org/articles/4/273…

Hey! I'm on the hunt for braided river data. If you know of papers (or have data that you're happy to share) detailing hydraulic geometries (e.g. depths, widths, slopes), discharges and velocities of braided rivers, could you flag them to me, please? It would be a huge help 🙏😍

Fantastic tour of river avulsion styles by @ValenzaJeff, I think retrogradational avulsion is my favorite. agu.confex.com/agu/fm20/meeti…

Beautiful field test of linear stability analysis applied to proto-dunes in bimodal wind field by Pauline Delorme agu.confex.com/agu/fm20/meeti…

Fascinating work by @RachelGlade on solifluction lobes, an enigmatic Arctic landscape pattern. Prospective grad students, consider working with Rachel, she's awesome! agu.confex.com/agu/fm20/meeti…

Some AGU highlights so far: @himaglobe will change how you think about levees: agu.confex.com/agu/fm20/meeti…

Check out our new paper! We find that coupling between bifurcations in a delta network can produce chaotic flux partitioning dynamics, implying that in the long term, delta networks are fundamentally unpredictable. pnas.org/content/early/…

@GeoMorphNick @jscarto @NASA_Landsat It looks seasonal to me.

@GeoMorphNick @jscarto @NASA_Landsat Cool! I've always thought this type of glacier is suspiciously delta-like. I need to see this slowed down; the light makes it hard to tell.

The uniquely long record of @NASA_Landsat enables scientists to track and quantify decades of change at the iconic Malaspina Glacier earthobservatory.nasa.gov/images/145574/…

@RobertCMahon Fantastic! How long did it take to collect that profile with the LISST?

@ebgoldstein @fkratzert Isn't predicting "out of sample" very different than predicting "outside of the range of conditions" provided in the training data? The latter would be surprising unless there are no strong nonlinearities/thresholds.

Here is our statement @fkratzert ... from doi.org/10.1016/j.ears…

“The argument that process-driven models may be preferable in out-of-sample conditions may not hold water.” (@fkratzert et al in @EarthArXiv doi.org/10.31223/osf.i…). I strongly agree with this statement, and tried to say the same thing in our Coastal ML review paper.

@ThomasM_geo @RobertCMahon Many schools don't tell their students about the fees or keep upping them (eg LSU) and it really shouldn't be legal. I agree if you have the fees it needs to be clear in the offer letter. At least I was warned before coming to Minnesota.

@RobertCMahon I guess it all goes into the offer letter, little difference in 21k stipend with 1k fees vs 20k stipend. But I prefer the no fees, cleaner and easier to budget.

@RobertCMahon The Yukon?

@docsnowtx @AmyEast_gmph It's because we've been trained for years and years in school to "lengthify" our writing to meet arbitrary word or page counts.
