Another Retaria day, remember to sign up for the seminar series “The Life of Retaria”! thelifeofretaria.github.io/index.html
Great to see more work from our culturing seasons in the Arctic twin to @juliemeilland.bsky.social and my @chalkyoceans.bsky.social Mediterranean culturing space, housed in the @exoceanlab.bsky.social at @climatecerege.bsky.social.
New paper out on planktonic foraminifera respiration. Interesting findings on polar and subpolar species! Congrats to Diane Armitage! With Audrey Morley, Nicolaas Glock, part of the Arclim group, Tali Babila and co.! bg.copernicus.org/articles/23/...
The impact of essential climate variables on respiration rates in subpolar and polar planktonic foraminifera
Abstract. This study investigates the impact of Essential Climate Variables (ECVs) on the respiration rate of polar planktonic foraminifera Neogloboquadrina pachyderma and subpolar Turborotalita quinq...

We got our first common paper out #theLifeOfRetaria with @sandinmm.bsky.social , @raphaelmorard.bsky.social, @nicolecoots.bsky.social, @mattgr3co.bsky.social, Nicolaas Glock and Natalia Llopis-Monferrer - first product of our seminar series! check it out! onlinelibrary.wiley.com/doi/abs/10.1...
Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution,...

🚨PhD alert 🚨 together with @tbiard.bsky.social and myself, based mostly in Wimereux with multiple stay in the beautiful @exoceanlab.bsky.social and focused on planktonic rhizarians C export and respiration. Get in touch!
Burning to learn more about marine protists as an early career?! This is for you! Apply and join one week of fantastic field-based summer school
Protist lovers: Please apply for a week of rhapsody! Learn by doing: MicroSEA (Microbial Sea Eukaryotes) course is a one-week, field-based summer school to train early-career researchers in the diversity, ecology, and single-cell biology of marine protists. opbc.sciencesconf.org #protistsonsky
In the changes to the 2026 and 27 @erc.europa.eu Work Programmes one can find : applicants who have been victims of gender-based violence or any other kind of violence will be able to obtain an extension of the period following their PhD to apply for Stg and Cons. Grants. Thousand claps! 👏👏👏👏
#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!
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!

Alt: mariah carey is wearing a santa suit and smiling. All we want for Xmas (and other denominated vacations) is you to come and do some cool science with us.

#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. 🦚
#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 14 Footprint reduction: we do lab-based ocean science because we genuinely love it, but also because lab experiments can replace lots of field trips. More control, more insight, and in part, fewer emissions. Bonus: dissolving old sediment cores neutralizes a bit of CO2. 😇
#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 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 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.
#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 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
#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.
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.
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!
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!
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!
Join us as a postdoc with the amazing @sulpis.bsky.social in the exciting @exoceanlab.bsky.social
Sediments dissolving on the seafloor can act as a long term sink for carbon dioxide emissions. We're bringing it to the lab, deep sea research from the comfort of Southern France! Postdoctoral position for 2 years available working with @sulpis.bsky.social in the @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* 😅
🌟 Postdoc Opportunity in Marine Biogeochemistry at CNRS-CEREGE! 🚢 Are you a passionate researcher ready to tackle climate change? Dive into the ERC-funded Deep-C project in Aix-en-Provence, France! ⬇️
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
