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!

#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!

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* 😅

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 @bmc.springernature.com

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.!

«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.
