Our newest paper looking at river avulsions from space is now out in @Nature! Huge congratulations to @JakeGearon for taking the lead on this project, and @HoosierRiver for excellent supervision, as always. Check out the fun thread below, and give Jake a high-five if you see him.

[James (Jake) Gearon @JakeGearon]

🚨 New Paper Alert!🚨: Excited to share my latest work in @Nature on river avulsions—catastrophic shifts in river courses that threaten millions worldwide. We've uncovered new rules that govern when and where avulsions occur. https://t.co/BFxd5Sp0jV

One of the first diagrams Earth Science students are shown is the source-to-sink diagram of Earth's surface. And yet this framework has never been tested across the modern Earth surface — until now. In their new #Geology article, @Caltech researchers Martin (@AvulsedCanuck) and Lamb harmonized global data products to make a global database of Earth's sediment sources, bypass zones, and sinks. https://t.co/7oNdy7P3BF #GSAPubs

My first (formal) collaboration with archaeologists is published! Was happy to learn more from them about one of the US's most remarkable places, and provide some drone-based lidar in return. Thanks to everyone else on the team!

@GSAPublications @Caltech Thanks for the share! Happy to chat about the paper with whoever is interested. We also made an interactive website to view the map without having to download the original files (though they are publicly available for anyone to use in the future!)

I was thinking about all the ways to describe the types of scientific papers out there. For example, there's the Tug of War paper, where the paper is framed as a tense debate with two strongly opposing sides. You come in and side with one side and become a hero for breaking the tension. Nature loves these types of papers.

Tomorrow morning, I'll be presenting some work on figuring out how rivers maintain width as they meander. It'll be in the Rivers across Scales session here at AGU (EP31A). While I'm a bit biased, the lineup of speakers looks great and I'm excited to see the rest of the talks!

[Harrison Martin @AvulsedCanuck]

If you've ever wanted the chance to get your hands on the drone-based lidar hardware that I've been showing over the last couple of years, here's your opportunity!

🚨🚨POST DOC ALERT 🚨🚨
Join my group at @IU_EAS to work on floodplain sedimentation and oxbow lake formation. Effort may include modeling, fieldwork, lidar, or remote sensing. Email me for more information! Full ad: https://t.co/lROPwrT7al

Very likely a tornado on the ground right now in far northwestern Monroe County — but it will NOT impact Bloomington in any way. Sirens are now going off, but this tornado is 10+ miles from the city.

[Harrison Martin @AvulsedCanuck]

@GeoJiamin @TUDelft_CT Huge congratulations, and great news! A big gain for them.

[Josh Ahmed @GeomorphicJosh]

Some really neat insights on meander dynamics from LiDAR scans and numerical modelling #AGU22

[James (Jake) Gearon @JakeGearon]

For all my #AGU2022 people! If you want to see how @HoosierRiver and I are leveraging space-borne lidar (@NASA_ICESat2) to study river avulsions, come check out my talk TODAY @ 5:15 CST in session EP16B! room S105D. 🤓

[Cody Kirkpatrick @codykirkpatrick]

Currently in Bloomington: 48°F, overcast, a little fog, calm winds.

Unsurprising just now: a Canadian, @AvulsedCanuck, just said affirmatively how nice a day it is.

Surprising: I, a southerner... agreed with him?! The lack of wind, for a change, makes it decent out there.

[Harrison Martin @AvulsedCanuck]

@HoosierRiver @indianaclimate @GeomorphYuggs @IUBloomington You mean that they "restored" it into a canal. 😢 https://t.co/Nd3hweljgw

[Harrison Martin @AvulsedCanuck]

I'll be giving a (free to the public!) talk tomorrow (Oct 27) on drones, lidar, and the science of landscapes. It'll hopefully be understandable, even to non-specialists, and maybe even... fun? 2pm Eastern, 11am Pacific. Thanks @IRIS_EPO! Register:

After four years as this guy's grad student, I can vouch for it being a fun time! Consider applying. DM me if you have any questions for a current student.

[Doug Edmonds @HoosierRiver]

As you make coffee do you think about sediments and porosity? Do you stare longingly at meandering rivers? As leaves fall, do you compare tree branches to delta channel networks?

Come to IU for graduate school! I am looking for new students, application due Jan. 6.

@RebeccaLave @HoosierRiver @seQuinndaryFlow There was also a weirdly satisfying but also uncanny feeling from seeing those "too perfect" sinusoidal channels... But I understood as soon as you mentioned AutoCAD!

[Harrison Martin @AvulsedCanuck]

Hey #GSA2022 folks! I'll be presenting (virtually) today at 2:45pm Colorado time. Here's a sneak peek of my talk: "Morphodynamics of a point bar and cut-bank on a rapidly meandering river revealed from twenty drone-based lidar scans", with @HoosierRiver & @seQuinndaryFlow.

[Harrison Martin @AvulsedCanuck]

@RebeccaLave @HoosierRiver @seQuinndaryFlow Thank you so much! That's kind of you. I also really, really enjoyed your talk! That research was so cool. Not only did it sound both fun and genuinely useful to society, but also a perfect example of work that can't be done without *both* geomorph and social sci. Eye opening!

[Harrison Martin @AvulsedCanuck]

@mishelfluvial @HoosierRiver @seQuinndaryFlow Thank you so much! I enjoyed your talk, too. It was great to learn more about gravel bedded rivers... Plus selfishly, I always love seeing more Canadian study areas!
