Great idea. We should rescue all the papers and data. Universities should provide a place to publish them so they are accessible to anyone. 📝

Four days later, I think I can finally process this: I’ve been awarded a Marie Skłodowska-Curie Postdoctoral Fellowship (#MSCA -PF 2025). 17,066 applications this year. ~9.6% funded. Still feels slightly unreal.

CO2-driven warming during the Pliocene can be used as an analog for present-day warming. A temperature record from a Colombian sedimentary core suggests that the tropics were 4.8 °C warmer in the Pliocene than during the late Pleistocene. In PNAS: https://ow.ly/iJ1c50YbG8B

Paper Alert❗️We present the first Oligocene record of orbital variability in abyssal ocean temperature based on benthic foraminiferal clumped isotopes. Temperature changes up to 4 degrees C with a 110 kyr pacing, indicating Antarctic ice-volume at this time was less dynamic than previously thought.

#exocean advent calendar day 24! Today we thought it was a good fit to show an image/talk about “conception”… One of the thing we (try to) do best at ExoCean is planktonic foraminifera reproduction. Here two immaculate mummies… 😏 We would like to wish you all a beautiful Christmas Eve!

#exoCeanadvent Day 23: at exoCean we also look at some old questions: in the late 1800s, during the HMS Challenger expedition, they discovered that you can have a constant rain of shells from above, and still end up with a seafloor that looks like the carbonate budget never existed. Why? Pressure. 🌊

#exoCeanadvent Day 22: Winding down for the holidays often means one thing... more mass spectrometry time is available! With our friends in @cerege.bsky.social's #ENVITOP facility, we're making use! Thanks to their equipment we're working on measuring elemental compositions down to the nano-gramme!

#exocean advent calendar Day 21! The strongest link between all of us is our love for the ocean. Leaving Marseille with a magnificent sunrise reminds us each time we go out how lucky we are to do what we love for a living! We already have our ship time for the first 6 months of 2026 - exciting!

#exoCeanadvent Day 18: looking for a good read waiting for Santa? 🌊 Try marine carbon removal: @sulpis.bsky.social co-chaired the working group behind the @emarineboard.bsky.social MRV brief, because “trust me bro” isn’t a monitoring protocol. Emissions cuts first; then *maybe* carbon removal.

#exoCeanadvent Day 19: Friday edition: today’s post is about the peacocks at CEREGE, because it’s Friday and our brains are in weekend mode. They wander around like they own the campus, scream for no reason, and block paths with absolute confidence. Honestly, goals. 🦚

Read the European Marine Board report here: 📘👀 www.marineboard.eu/publications...

And...you. 🫵🏼! If you want to come work with us then get in touch. Message us here, or head to the website in our profile details. 'Tis the season*. *Of @cnrs.fr applications, good luck to everyone who is applying!

#exoCeanadvent Day 20: it's wishing time... Whether you believe in Santa (the French singer 🎤), FC, or as I recently heard, Professor Xmas... We can all hope for some things in the holiday season... At @exoceanlab.bsky.social we would like (in no particular order):

#exoCeanadvent Day 16: We're getting closer to the holidays, but we don't stop yet. @erc.europa.eu postdoc @jysuarezibarra.bsky.social was out today presenting his work @maxplanck.de in Mainz. @soniachaabane.bsky.social is also visiting to chat with colleagues.

#exoCeanadvent Day 12: End-of-year celebration - raclette edition. On the agenda for this team meeting: cheese, cheese, cheese, goals for next year: even more cheese. We’ve officially reached our melting point. 🧀

The results did not reveal significant trend among the treatments, suggesting that under the tested conditions, the addition of olivine did not appear to affect foraminifera biology. Good news! Also, if anyone needs water filtration in the field with no electricity, Maxime is your guy.

#exoCeanadvent Day 9: Meet Maxime (again). At @exoceanlab.bsky.social and @climatecerege.bsky.social Maxime has been conducting several experiments focusing on the culture of marine organisms. One project involved culturing foraminifera in the presence of olivine (Mg,Fe)2SiO4, an igneous mineral.

#exoCeanadvent Day 10: As winter creeps into Provence we remember warmer days from our fieldwork in Bermuda. We stayed with the lovely folk at @biosstation.bsky.social, like @blancobercial.bsky.social who helped us to look for different foraminifera to catch, than our usual Mediterranean stuff.

#exoCeanadvent Day 11: Science makes you do strange things. Meet @astridhylen.bsky.social, a postdoc working with carbonate dissolution in coastal sediments. She recently found herself in the middle of a salt marsh, stirring one of the ponds with a (clean) toilet brush taped to a curtain rod.

#exoCeanadvent Day 8: Meet Katoo Declerk's Erasmus+ work. During her internship Katoo is investigating recently dead foraminifera (handily available in our lab!) Forams typically sink to the ocean floor soon after death, but partial or total dissolution can occur before getting there.

Once finished, these measurements will be combined with CT scans, and modelling to work out exactly what is happening in these first stages of sediment formation, or indeed alkalinity recycling in the water column. Stay tuned for results later in Katoo's project!

#exocean advent calendar Day 7! We are lucky to be based in a pine forest, in Southern France, which means loads of possible walks to discuss science in a wonderful environment. We also like to run together - as we did Friday to finish the week!

#exoCeanadvent Day 4: At exoCean we also investigate what happens to calcifiers who mysteriously die (answer: a lot happens). For that we must go at sea and collect evidence, just like CSI but with more seasickness pills, same sunglasses.

Day 2 of #exoCeanadvent: Come with us to sea (you can also be a land based participant). As an 'inland' ocean lab, we don't quite have the sea on our doorstep, but that doesn't mean we can't bring it to us! We're based just 30–60 minutes from boats out of Marseille and Toulon.
