#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 16: We're getting closer to the holidays, but we don't stop yet. @erc.europa.eu postdoc @jysuarezibarra.bsky.social was out today presenting his work @maxplanck.de in Mainz. @soniachaabane.bsky.social is also visiting to chat with colleagues.

Jaime introduces his project and ForCry at a team seminar in Mainz. 📷 S. Chaabane

#exoCeanadvent Day 17: Net accident, happy outcome. Ex-lab member Laura caught this phronima (monster in a barrel) “by mistake”, so we adopted it - alive - in a lab aquarium. One haul turned into days of behaviour notes.

#exoCeanadvent Day 15: Some plankton are tiny [citation needed?], and for those we need ways to measure tiny (this is a theme you'll hear us talking about a lot). Sometimes just holding samples in place can be hard.... enter the #Cryostage! ❄️

A rack of tiny samples, about 0.5mm in diameter... Here we've custom made some really clean rings to hold them in place... next step, freeze!

#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. 😇

Sometimes you can replace a boat trip with a car trip, ever wondered how much ocean you can get into a Golf?

#exoCeanadvent Day 13: Time Machine. Travel back in time with us 6 million years. Part of the reason for our work @exoceanlab.bsky.social is to better understand the past through observing the modern, but sometimes you just need some ancient mud..@chalkyoceans.bsky.social recently went to get some!

#exoCeanadvent Day 12: End-of-year celebration - raclette edition. On the agenda for this team meeting: cheese, cheese, cheese, goals for next year: even more cheese. We’ve officially reached our melting point. 🧀

The exoCean team and friends actively brainstorming on hot topics

#exoCeanadvent Day 11: Science makes you do strange things. Meet @astridhylen.bsky.social, a postdoc working with carbonate dissolution in coastal sediments. She recently found herself in the middle of a salt marsh, stirring one of the ponds with a (clean) toilet brush taped to a curtain rod.

#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.

Tom and Julie went out a few days ahead of the rest of the team to do a last minute check that all the islands and beaches and bars existed.

#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.

Don't eat that! A large foraminifera trying to eat grains of olivine. It soon realised that they weren't food, but had no problems afterwards, so... not poison!
