The Arctic's permafrost stores large quantities of organic carbon. Researchers from the AWI and @marumunibremen.bsky.social have shown that large quantities of this carbon, released by thawing permafrost and coastal erosion, are permanently buried in seafloor sediments. www.awi.de/en/about-us/...

The Arctic Ocean keeps permafrost carbon firmly locked

Permafrost in the Arctic stores large quantities of organic carbon. When the frozen ground thaws or coastal sections erode, this carbon can enter the sea, where microorganisms can break it down and co...

The president is a liar. He lies constantly & without hesitation. His lies about American elections are among his most dangerous b/c they are meant to convince a susceptible public that democratic outcomes cannot be trusted. They are antidemocratic lies in service of holding onto power. He’s a liar!

Canadian AQI model has joined the U.S. models in predicting potentially record-breaking smoke levels Wed-Fri in the Great Lakes. A bad look for the Detroit, Milwaukee, Cleveland, Buffalo, and Toronto metro areas. The EPA site to judge records is down, not removed, as I incorrectly stated before.

NEW: A lot of bad has happened to American science over the last year but nothing comes even close to what’s about to happen if we don’t speak out in opposition to the OMB rule changes and I hope @aaas-socsci.bsky.social @apsphysics.bsky.social and others will launch public campaigns about this. 🧪🔭⚛️

It's the End of American Science As We Know It

We have 45 days to express our opposition to catastrophic changes.

🧵 Public science in the US has taken some heavy hits over the last year, but the White House OMB is proposing a series of changes that will result in a TKO for science as we know it unless we fight back. Here's what's happening, and why it matters. 1/n

🚨New paper alert! Former UMaine M.S. student, Jill Herlinger (now at Northwestern), led a brilliant paper that utilizes Mg/Ca and δ¹⁸O on foraminiferal calcite in the Gulf of Maine to show that that the Laurentide Ice Sheet was melting and retreating like crazy during Heinrich Stadial 1... 1/

Rainfall intensity matters as much as how much rain falls. New in Nature: Corey Lesk and I show that daily-scale concentration of precipitation dries the land over the long-run, an effect as strong as total precipitation is climatological wetting. Paper here: www.nature.com/articles/s41...

More concentrated precipitation decreases terrestrial water storage - Nature

Concentration of precipitation in large events decreases land water availability, and this effect will further increase with a future warming climate.

As many know, there was a massive fire at USF CMS. The building held offices, labs, equipment, etc and is a total loss. We are most concerned about the finanpcial losses of our students. Please consider donating to the official go fund me supporting our graduate students.

Just published: our comprehensive review of bacterial hopanoid & steroid biosynthesis, function, evolution, and diagenesis. We cover decades of research across multiple disciplines and highlight many remaining open questions. More context provided below👇 link.springer.com/rwe/10.1007/...

Bacterial Hopanoid and Steroid Biosynthesis, Function, Evolution, and Diagenesis

A wide diversity of bacteria produces hopanoids, which are pentacyclic triterpenoid lipids. A smaller subset of bacteria produces steroids, tetracyclic triterpenoid lipids that, like hopanoids, are bi...

And if you have not been accepted, understand that this is a VERY weird time for grad admissions. Lack of acceptance may not be due to YOU, but due to uncontrollable factors at the university. Keep trying in the future.

Annual reminder: if you’ve been accepted to multiple graduate programs and are still deciding, please let the ones you’re definitely not going to know as soon as possible! -Someone who got into his PhD off the waitlist the day after the deadline

Stoked to contribute to this excellent work by Chandranath et al. reconstructing the circulation history of the deep South Pacific across the MPT. When accounting for endmember Nd isotope change, the records point toward Southern Ocean processes as initiating the MPT 👀👀
