Bravo Louise!!

Bravo @juliemeilland.bsky.social!! 🎉
Well deserved 🍾

So excited to see how this revolutionises foraminifera work. Well done and deserved @juliemeilland.bsky.social, but not sure I can ever forgive you for getting me into the "living stuff" !!

Thank you so much for everything! you were part of this success too! 🥰
And huge congratulations to you as well for the new position, I’m so happy our paths will keep crossing! I’m strictly “team flat ground”. Expect some breaks, lot of complaining and photos as an excuse to stop walking 🤣⛰️

Thanks @sulpis.bsky.social !!! Thanks for all the help and for everything, always. Looking forward to the next decades with you!

Thank you so much @juliemeilland.bsky.social !!! Thanks also for all the support I received from you during all these years! ❤️

So happy to have our first publication together!! looking forward to many more collaborations ahead!

🐚 Small shells, big impact.
Proud to contribute to this collective effort revealing how microscopic calcifiers are key players in Earth’s carbon future. 💙🌎

By comparing CaCO₃ production, shallow export, and burial, we show each group follows a unique pathway.
Future climate impacts will be group-specific, yet current models cannot capture this diversity.

We compare functional traits of the three major calcifying groups, coccolithophores, foraminifera, and pteropods, and evaluate how these traits shape their roles in carbon and alkalinity cycles, and sensitivities to climate change and ocean acidification.

Calcifying plankton: From biomineralization to global change The cycling of calcium carbonate (CaCO3) in the ocean is closely linked to seawater alkalinity and the regulation of atmospheric CO2. In the modern pelagic ocean, almost all CaCO3 is produced by three...

Excited to share our new paper out today in Science led by Patrizia Ziveri and the BIOCAL Working Group!
With @willerstorfi.bsky.social, @nanophyto.bsky.social, @tdegaridel.bsky.social and many colleagues!

The lab keeps evolving and we are THRILLED! More equipment is about to arrive, some more is planned, and we feel super excited about our different projects. Also really… what a view when the doors are open, one can even see the emblematic « sainte victoire » behind the trees!

Exciting chance to join the ERC-funded Deep-C project with @sulpis.bsky.social at CNRS-CEREGE in Aix-en-Provence 🇫🇷.

If you’re passionate about oceans, climate change, and marine biogeochemistry, this is your call to dive into world-class research 🚀.

📚 Requires a PhD in geochemistry/oceanography.

Apply by mid-Oct here: emploi.cnrs.fr/Offres/CDD/U.... We'll extend to end of October if needed.

The authigenic and detrital neodymium isotopic composition in the modern Mediterranean Sea: implications for paleocirculation proxy Neodymium isotopic composition (143Nd/144Nd or εNd) has been used as a tracer of water mass provenance in the modern and the past oceans. However, rec…

Nice comparison of foram-coating derived and sediment derived #Ndisotopes in the Mediterranean from Kazuyo Tachikawa and others @climatecerege.bsky.social and @cerege.bsky.social. Small cautionary tale for unrestricted use (of sediment), but normally it works!

Watch this space for so much new exciting science from the new influx of Ceregiens. @cerege.bsky.social

Anta delivering her #ICP15 talk in Bengaluru.

Future (and past) @climatecerege.bsky.social superstar @antacl.bsky.social giving her #ICP15 talk now. Modelling the Indian monsoon in the Miocene, and some important praise to the organisers for their diverse programme of speakers. Bravo!

Thank you so much for the invitation #ICP15. Diversity makes us stronger, and the data shows it! ⏩🏳️‍🌈

Miso is the best!
Big thanks to @tdegaridel.bsky.social!
Stay tuned for the next Miso generation!

Lovely to hear from @chalkyoceans.bsky.social about need for #diversity (of careers, people, methods and
minds) that underpins our working 🙏🏼 #ICP15

@antacl.bsky.social you are my favorite ❤️
