Schematic of the Deep-C high-pressure reactor and in situ sensors.

#exoCeanadvent Day 6: To study the deepest ocean trenches, we’re building reactors that make our lab behave like the deep ocean. Funded by @erc.europa.eu #Deep-C, they will hold cold seawater at ~1000 bar (10km water) so we* watch pressure shape chemistry and biology 🔬🌊

*mostly @sulpis.bsky.social

A schematic graph showing global temperature, plotted against CO2. We know CO2 increases temperature, but the how far and how fast are still not totally constrained. Tipping points, or sensitivity changes could impact this relationship in the future, and may have done in the past.

#exoCeanadvent Day 4: Why did we set up this lab? Part I. What is going to happen to climate as CO2 levels go up? @chalkyoceans.bsky.social and @erc.europa.eu project #ForCry look at CO2 in the past to better understand climate sensitivity. Part of this is making better past CO2 reconstructions.

A plankton net (think large wind sock) hangs from the back of a boat. We use these to conduct surveys of the ecosystem and bring back live plankton to the lab.

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.

Merci, tjs pas la réf 🤣

Merci!

I was awarded the Alan Higgins Award by @micropalaeosoc.bsky.social for my work on planktonic foraminifera reproduction and culture. I feel very honored and can only thank all the great colleagues who supported me along the way in Norway, Ireland, the UK, Germany and France!

Well well well deserved! Congrats again!

Slowly but surely the lab we had in our heads with @sulpis.bsky.social and @chalkyoceans.bsky.social is coming to life. High pressure incubators are about to come, more microscopy equipments… Such a nice adventure has started!

Join us as a postdoc with the amazing @sulpis.bsky.social in the exciting @exoceanlab.bsky.social

Come work in our lab! All the usual awesome things apply about doing exciting science, plus this one might save the world! @sulpis.bsky.social hiring a 2 year position to observe and model deep ocean processes using high-pressure reactors.

*Goes to gather a bunch of forams to be dissolved* 😅

Hi @oceanhelen.bsky.social, super interesting! I was wondering (still am as we need more data) what the effect of such a warm event would be; we could have sampled only sad forams or empty shells…

End of June was particularly warm in southern France and the Mediterranean Sea experienced very high temperatures (28 degree Celsius?!). We were lucky enough to have ship time and sample days later. Today we’re going through the samples - full of truncs! @exoceanlab.bsky.social

If you have interesting science to share on ocean ecosystems sensibility &/or OA etc, consider submitting it to the upcoming collection « Ocean Ecosystem Services and Sustainable Development Goals » of the new Springer Nature journal Ocean Ecosystem! bit.ly/3FzQH7E

Great week of scientific talks at the ICOP/ISOP 2025 in Korea and some nice work done with @raphaelmorard.bsky.social, Mattia Greco, @sandinmm.bsky.social, Nicolaas Glock and co.!

Yay!!

«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 💪🏼

Bermuda cave sampling today with @blancobercial.bsky.social for these little monsters (lovely forams)! Thank you Leo, @chalkyoceans.bsky.social, @biosstation.bsky.social !
@exoceanlab.bsky.social

Having fun in the lab @biosstation.bsky.social with @chalkyoceans.bsky.social, @thefosterlab.bsky.social and co.

Look at this beauty! freshly fished out of the Sargasso Sea and imaged at the Bermuda Institute of Ocean Sciences with @chalkyoceans.bsky.social @juliemeilland.bsky.social and others 🧪🌊⚒️

With the « Life of Retaria » we do podcasts! Listen to the first one during which we interviewed @fabnot.bsky.social #protistsonsky

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

Check what we do and follow us @exoceanlab.bsky.social

🚨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.

@exoceanlab.bsky.social

Interested in doing a PhD with living planktonic foraminifera? Come work with us! Check our PhD subject and get in touch! @tdegaridel.bsky.social

Hey! No I never saw that… looks really strange! Is that little bubbles everywhere?

Thrilled to announce that I officially started my new job as a @cnrs.bsky.social researcher in the @climatecerege.bsky.social, France. I am very thankful for the support I received for my project. Amazing views of Provence and a running lab, already with living forams to play with - what else?!

Not all adaptation strategies to #climatechange will be sufficient for planktonic #foraminifera to survive, an international team of researchers with #MARUM participation comes to this conclusion in the scientific journal @nature.com ➡️ www.marum.de/en/Climate-c...

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 ...

Can we (and by we I mean foraminifera) migrate our way out of the climate crisis? It doesn't look like it. Massive study by @soniachaabane.bsky.social with @tdegaridel.bsky.social, @juliemeilland.bsky.social, @sulpis.bsky.social, me and others!
