TFW you have been trying to get a permit for The Wave for years, without success, and then you get not one but two permits for the same day

Will be giving one of the last talks today at #AGU25, focusing on how well simple curvature-based models work on meandering rivers with a range of sediment loads. It turns out these models are not so robust if the sediment load is high and the river is migrating with crazy-high rates

Photos from the Patapsco River in Maryland yesterday. Lucky to have the snow stick to the trees despite the high winds! #riversfromabove

Downstream fining on a point bar, Trinity River, Texas. Scale bar units: centimeters in first photo, millimeters in the rest 🧪⚒️

A couple of days ago we went to check out one of the most beautiful bends of the Trinity River in east Texas, a bend that is likely to be cut off in the near future 🧪⚒️

While cleaning up I came across a large set of TIFF files. Zooming turned out to be worthwhile. Had to look up where it is. Here we go: a small part of the amazing Haast River, West Coast Region, New Zealand.

Didn’t know about this event but was wandering in the NOMA today to clear my mind and there it was: so for AGUans… Wednesday evening at New Orleans Museum of Art! Which is close to my house 😀

Fluorescent barite from the “Skunk Pocket” at Linwood Mine, Iowa. Not much seems to be known about this find except that it was a small one from around 2019. Shown under longwave UV (365nm). Visible light comparison in comments. Person collection, photo my own. #geology #uvphotography #barite

A good introduction to power law distributions and their links to fractals, self-organized criticality, forest fires, networks, and earthquakes - although it would have been nice if they included more domain-expert perspectives and hinted at the limitations of these models youtu.be/HBluLfX2F_k?...

The Schelde (Scheldt river) east of Gent (Ghent), Belgium, once meandered widely and is now a relatively narrow river, a change that likely occurred in the Late Weichselian.

Listening to this was a lot of fun. Disclaimer: I haven’t read Yuval Noah Harari’s book. And, after listening to this, I never will

What the ACTUAL FUCK, Kīlauea?! Go check it out yourself in the livestream right now. 👇 ⚒️🧪 #volcano www.youtube.com/live/tk0tfYD...

Truly the stupidest cult. Obsessed with a drug that doesn't work against an infectious disease that they don't even think is real.

Delighted that one of my Antarctic winter photos has won the 2025 Royal Society Photography Competition, Earth Science & Climatology category. Captured during polar-night surveys of ocean conditions near Antarctic Peninsula glaciers. royalsociety.org/journals/pub...

One of the first uses we put our myst/any-widget interface to was to expose vizarr in Curvenote articles - vizarr being a popular JS viewer for the OME Zarr format. (The vizarr being the work of @manzt.sh and others at hms-dbmi) Some examples included 👇 opensci.dev/articles/019...

Wherever you can, whenever you can: exploit this crack, wedge it apart, and lever it open, until the whole insane edifice disintegrates and the fleeing rats are crushed into ignominy. newrepublic.com/article/2037...

A Sharon Begley byline, almost 5 years after her death. Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written." Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating. 🧪🧬🧫

Moqui marbles - concretions from the Navajo Sandstone in Utah (images created from a photo taken in the field) 🧪⚒️

Dang, hard disagree. The best papers to write and read are works of art, not merely a list of data and statements. Don’t let LLMs take this away too, for gods sake.

Trying to decide which Matplotlib colormap is a good colormap for differentiating grains in an image

Tectonic plate puzzle anyone? 🌎 Made by me, one at a time. I’m planning to have a really limited number available before the holidays - if you want to find out when I do, sign up to my newsletter! I will share them through it first. Sign up > www.luciaperezdiaz.com#newsletter (No spam, I promise)

As I said before, I am not a big fan (to say the least) of using AI for writing or generating images / movies, but it has completely changed the game when it comes to coding. Again, this does not mean that you don’t need to know anything about coding or that the work is less complicated/intense.

lol she got his ass and he knows it

I got this cutting board and these coasters from Kurtis Burmeister’s Etsy shop and they are among my favorite objects in the house www.etsy.com/shop/Burmeis...

I just blocked all emails from MDPI journals in my email app. They are relentless. They are the worst.

TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10/NSF-... 🧵

The perplexing (to me, anyway) phenomenon of laminated loess deposits (Bignell Hill, Nebraska)

A new study argues that in the past, Cascadia quakes have triggered the San Andreas to go off, and that it could happen again. But other experts, while recognizing that may technically be possible, want more evidence. Read more at NatGeo: www.nationalgeographic.com/science/arti...

I was recently interviewed by @drlauraguertin.bsky.social as part of her 'Tales from the Deep' series focused on the people involved in scientific ocean drilling ⚒️🧪⛴️ –– lots of great stories from many others there to check out archive.storycorps.org/interviews/i...

Today was a good day. #nokings protest, Austin, Texas

It can not be exaggerated just how wild the climate of the Pleistocene was in which we evolved. All of recorded history is in pixel at the very top of the very last zigzag, all the way to the right of this graph. From a new paper on sea level over past 4.5 million yrs www.science.org/doi/10.1126/...

Next week at the #GSA2025, I'll be presenting my newly developed Python tool, 𝒑𝒚𝑪𝒐𝒓𝒆𝑹𝒆𝒍𝒂𝒕𝒐𝒓. We apply it to quantitatively re-examine the correlatability of Cascadia deep-water turbidites, previously interpreted as synchronous deposits of paleo-earthquakes. Abstract: lnkd.in/gJ_KHH2j

Headed out into the field. Josh printed out 3D maps of the region for reference. ⚒️

Did you know that sand records its transport history as it moves across Earth's surface? We developed a new tool to investigate billion-year-old rocks by looking at microscopic features on zircon sand grains. Check out our new paper in @geosociety.bsky.social to see how! doi.org/10.1130/G537...

It was a pleasure to contribute to this article, which talks about how AI contributes to seismology - indeed, we have seen tremendous progress in the use of machine learning to detect small events. 1/

An excellent response by MIT’s President Sally Kornbluf rejecting the Trump compact. Other universities should do the same.

It's not a big deal but I find it annoying when I am told to use only one slide (or three, whatever) when giving a short talk. I am old enough to figure out how to use visuals in a limited amount of time; let me decide if I want to use fifty slides or none

ah the leaves are turning and the men are giving each other prizes again the first whispers of winter

It appears that my employer, Dartmouth, one of the Trump 9, has said no to the compact. All the better given that our president is cited within it. But she’s saying no. Count the small victories when they come.

“It trades autonomy for subservience, academic freedom for censorship, gender science and history for ideology, and the best interests of UT students and faculty for the favor of an administration intent on destroying our university.” www.texastribune.org/2025/10/02/u...

This is so, so horrible. Who are these unaccountable government agents? What gives them the right to abuse people this way? Where is due process? I weep for these poor children, and I weep for the nation that condones this abominable treatment. This behavior is sadistic.

its this part "If universities sign and then violate the terms of the compact, they could be forced to return any money given to them by the federal government that year as well as any private contributions." 👀 Stay in line OR ELSE

I also like to use some of their examples from previous underwater experiments (Reffet et al., 2010; doi.org/10.1130/G308...) to show how acute and obtuse diverging winds result in different dune types (inspired by @agunn.bsky.social 's Sharp Lecture last year):

When the dust will clear up...💨 Preparation of Morteratsch Glacier samples (Little Ice age, 1st two), Fee Glacier (Roman Period) and Mer de Glace (Bronze Age) today! 🤩🌲💍

Great example of a flood produced by the end-of-monsoon-season rainstorm on an ephemeral desert stream with a drainage area of 1817 square miles. A bit west of Phoenix.

I've been asked a few times over the last few days what I think the chances are that the "leopard spots and poppy seeds" on Mars will turn out to be actual evidence of life. People are naturally skeptical given the history of possible signs of life on other planets. Strap in: long thread ahead...
