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!

exoCean Laboratory @exoceanlab.bsky.social · 6d

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!

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

«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're away from our lovely light and temperature controlled incubators @exoceanlab.bsky.social, but that doesn't mean we can't keep our plankton happy. @biosstation.bsky.social water baths to the rescue. If you've ever wondered what culturing for trace isotope systems looks like, it's this! #d11B

Dozens of small plastic flasks, each containing an individual foram sit in a temperature controlled water bath, under lights.

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...

Planktonic foraminifera are tiny marine organisms that are important for the marine ecosystem. In response to the increasing warming and acidification of the oceans, they are migrating deeper into the sea to preserve their populations. Photo: Sonia Chaabane & Julien Sulpis
