🌊📉 New Paper Alert! "Migrating is Not Enough for Modern Planktonic Foraminifera in a Changing Ocean" published Open Access in Nature🧵👇

Migrating is not enough for modern planktonic foraminifera in a changing ocean - Nature

Low-latitude planktonic foraminifera are coping with rapid ocean warming, acidification and nutrient shifts by migrating to deeper water-column depths or polewards, displacing higher-latitude species ...

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!

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!

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.

Huge thanks to @tdegaridel.bsky.social for making SASHIMI happen 🙏

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 🇸🇳❤️

«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).

Tom with a fresh plankton sample about to be poured into the collection bucket. It's white so they stay cool on the way back to the lab.

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.

Julie checks on her living cultures in a temperature and light controlled incubator.

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.

Tom is packing a large metal container ready for fieldwork in Bermuda, watch this space!
