Out online today in @pnas.org our paper: "Aerobic nitrogen cycle 100 My before permanent atmospheric oxygenation" With coauthors Gareth Izon, @chrisjunium.bsky.social , Shuhei Ono, and Roger Summons. 1/7 www.pnas.org/doi/10.1073/...

Whoa! Look at the field in the background.

#piday turned into pie weekend with some Neapolitan-ish pizza in the Ooni oven.

Pi day pie extravaganza. Chicken pot pie and non-dairy raspberry chocolate custard. Nice way to celebrate the end of a good week.

About fifty years ago, NASA strapped a message in a bottle to a rocket and flung it into the deep dark It wasn’t supposed to go this far, but it did. Long past its mission, it’s still out there so far away now that a simple hello takes a day to reach it, and another day to hear if it says hello back

I hope this helps someone www.forbes.com/sites/marsha...

Herman Melville's "Moby Dick" has perhaps the most memorable opening line in all of Western literature: "I hope you motherfuckers like reading about whales"

I feel like I do a lot of things pretty well, but there is nothing I do better than destroying the kitchen when I cook dinner.

Last post for #FossilFriday this lovely #Proterozoic #Acritarch because I love it so much. This image was taken with a macro lens at 2x attached to a microscope with a 100x mag lens. It's a combination of over 100 images stacked and stitched. #Geology #Paleontology

Beef Wellington pre-cook. I’m happy enough with this that even if it isn’t perfect, I’ll be ok with it.

Whatever happens to the water, happens to the people.

As a former whitewater kayaker I can say that duck took an excellent line and hit his boof off that rock perfectly in what looks like solid class IV water. If I paddled that well I wouldn’t be a former kayaker.

Dueling knives for the duxelles is a lot of fun.

All I want for #crustmas is a pair of these beauties.

Remember, a first draft's only job is to exist

"Butterfly Effect" is by far my favorite piece I've ever drawn. I know I keep sharing it, but I just hope it brings joy when people see it. (Plus I don't have a whole lot of new art to share.) #paleoart #sciart

Big changes in EAR programs! Check it out.

For anyone who thinks this is artistic whimsy, Palaeopagurus was REAL and we FOUND IT #Crustmas 🧪 onlinelibrary.wiley.com/doi/10.1111/...

The push advertising is hitting a little too close to home right now. Thinking of buying one though. It couldn't hurt right? #academia #science #research

As we enter the winter road-salting season, we need to remember how much damage oversalting does to aquatic ecosystems and our #drinkingwater. Sadly New York - the Salt King - lags behind other states in implementing Best Management Practices. #Salinization mohawk.substack.com/p/salinizati...

Please tell your kids, every damn day if necessary, that chatGPT is not a goddamn search engine and you shouldn’t believe a word it says. Tell the adults too, but it’s especially imperative to inoculate kids against this

Day 2 at #AGU24! Join me at the NSF Booth (1101) in the Exhibitor Hall from 4-6pm to learn more about the new Water, Landscape and Critical Zone Processes (WaLCZ) program new.nsf.gov/funding/oppo...

great ideas

More pics of the seaside cliffs near my home town in Newfoundland, Canada. Not a great place to fall on your butt! #geology #rocks

40% of the mass of everything transported by a ship in 2023 was a fossil fuel. That stat paired with this new study shines a pretty harsh spotlight on how obscenely bad-faith the right-wing concern trolling around offshore wind + whales is www.seattletimes.com/seattle-news...

I’m recruiting graduate students and a postdoc to work on a range of hydrology topics- from water quality in agricultural landscapes to critical zone process (a)synchrony! Interested? Let’s chat at #AGU24!!!

Walking across campus in this weather on salt strewn and icy sidewalks I saw a student reevaluating their choice to rollerblade to class.

Have you heard of acid-free dissolution?

Oh man, Croonchy Stars were goood. Bork, Bork, Bork!

@agu.org I’m not sure if it’s possible to do this last minute, but could you remove X as the default platform for posting on the #agu24 app? Aside from all the issues with the platform, we aren’t there anymore. We’re here!

"Under my leadership, we have instituted an assessment program where we assess how we assess what we already assessed, using learning outcomes that include all of the buzzwords someone in admin told us were important."

In a new interdisciplinary Nature Climate Change Perspective paper, led by me, @lisgilmore and Rachael Shwom, we offer a critical perspective on #climate and social “tipping points.” 🎁: rdcu.be/d2gBC 🧵

The way to get to do shit you want to do is to first do shit that you don’t want to do. #mentorship

There is something so ironic about debating with Westerners whether there is a meaningful distinction between democracy and dictatorship on the same day that Koreans demonstrate that they not only know the difference but will fight to maintain it.

Post an onion article that lives in your head rent free. Mine came true just a few years after this article when Gillette skipped 5 went straight to to 6. theonion.com/fuck-everyth...

Syracuse University just defeated Miami. iykyn.

Warm lake and cold air sets up for lake effect bombs. Syracuse can get its fair share of snow from time to time, but nothing like the Tug Hill area.

60 INCHES OF SNOW IN 3 days! How would you like to have THIS forecast? It's for Watertown, NY which is getting CRUSHED by Lake Effect snow. The total accumulation there through Sunday night could top 60 inches.

Visiting family now - this hits the bullseye. But how to get them to take the leap? They may hear me when we talk about it but they aren’t listening.

We ran a lovely feature about the experience of getting hearing aids last month: slate.com/technology/2...

Visiting my parents for thanksgiving and it’s just like being in the lab. I was tasked with changing car headlight bulbs. It is just like mass spec maintenance. I need to squeeze my hands into very tight places, reposition the flashlight, realize I have the wrong part, get new part, then success!

It’s a question we ask all the time.

"There are not many places on earth where we have detailed cause-of-death data from before the era of widespread vaccination. Massachusetts is one of those places. From 1842-1877, 70% of all deaths were from diseases which we today have vaccines to prevent." Worth sharing.....

Your name in Landsat imagery is amazing. If you keep resubmitting the request it keeps changing the image and it just got better and better.

Folks,
