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" !!

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! www.sciencedirect.com/science/arti...

My besties! ♥️ @chalkyoceans.bsky.social & @antacl.bsky.social Science has never been about competition! It’s about sharing, learning, and enjoying the journey together. Thank you for being such wonderful researchers and friends! #ICP15 @climatecerege.bsky.social

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

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! ⏩🏳️‍🌈

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

✨ Honored to witness the inauguration of the BISSAP lab at UCAD — a new lab for ecosystem monitoring in Senegal! 🌍🔬 Huge congratulations to everyone involved! @climatecerege.bsky.social @ird-fr.bsky.social #ScienceForAll #UCAD #IRD #Biodiversity #Africa #BISSAP www.ird.fr/inauguration...

🚨New paper alert🚨 Using the mean and 95th percentile of cross-sectional area measurements, we documented ecological and taphonomic imprints on the test size variation of planktonic foraminifera. @soniachaabane.bsky.social @chalkyoceans.bsky.social @tdegaridel.bsky.social doi.org/10.61551/gsj...

SASHIMI has arrived in Senegal 🇸🇳 Not the sushi!! the microscope. It scans tiny fossils with love, patience, and cables 🌀 From @cerege.bsky.social to BISSAP Lab, it crossed borders to help us see the invisible. Welcome, little scanner. Let’s make micro-history together 🇸🇳❤️ #ScienceHasNoBorders

«You can’t have it all» they said. After weeks of field work in Bermuda, partly with my little one and significant other, thanks to the support of the amazing @chalkyoceans.bsky.social… I feel very optimistic that it is possible. Keep going! There’s room for science and tiny humans in our lives 💪🏼

We then collect the live plankton and try to keep them alive long enough to get to the lab. There we can look at how they respond to different conditions in a controlled setting. (And if you know @chalkyoceans.bsky.social, you know there will be boron involved).

Excited to have hundreds of baby Forams in the lab after the first towing - different species - different behaviors! @exoceanlab.bsky.social @chalkyoceans.bsky.social

Julie Meilland, marine biologist at the CNRS, studies planktonic foraminifera — focusing on their population dynamics, life cycle, reproduction, and ecological role in the carbon cycle. Her research explores their adaptive potential as model species in the modern and future oceans.

Tom Chalk, an isotope geochemist (interested in the tiny variations in mass of chemical elements), specialising in boron, the 5th element. I am the Principal Investigator of the ERC project ForCry and CNRS researcher, interested in the natural history and unnatural future of Earth’s climate.

Olivier Sulpis, marine biogeochemist at CNRS. In the ERC Deep-C project, I combine experiments under crushing pressure with mechanistic models to investigate the fate of calcium carbonate in the ocean, from the dissolution of shells in the deep to the role of sediments as long-term carbon sinks.

🚨Hello world!🚨We'd like to introduce you to our new laboratory for "experimental ocean science", ExoCean (C is for carbon). We are three researchers teaming up to work on culturing, dissolving, & measuring marine samples. @juliemeilland.bsky.social, @sulpis.bsky.social & @chalkyoceans.bsky.social.

Sending buckets full of solidarity from Montpellier, France to the #StandUpForScience movement. Officially, with support from my institute #FRBiodiv @frbiodiv.bsky.social - and less formally with my #Cesab crew ✊🔬🌐🗽

🚨Postdoc Offer🚨 Fully funded 2-year research position at Paris or Aix-en-Provence: your choice! The project aims to predict OAE feedbacks and environmental impacts in the ocean interior, in particular at the seabed. See job ad : nuage.osupytheas.fr/s/4zMfHFZ8S2... Please share widely! ⚛️

Come work with us at CEREGE, in Provence, for a position at the intersection of science, communication and management!
