... you'll learn how to identify and separate tiny shells from old sediments, before analysing their chemistry in the lab.

You'll be based in Aix-en-Provence and using mass spectrometry (firing atoms really fast to learn what they are) to better understand past climate. We'll look at the changing ocean chemistry of the Pleistocene.

how evolution impacts the fossil record and our climate data from the all-important mid-Pliocene interval (~3.2 million years ago).

You'll be based at @climatecerege.bsky.social in Aix-en-Provence and looking at tiny fossil seashells called foraminifera. These shells lock away the ocean's chemistry and can be used as a Time Machine to explore past climate.

With @jysuarezibarra.bsky.social, me and others you'll explore...

Thank you to everyone who came to our workshops & @pages-ipo.bsky.social meeting, contributed to the special issue, the community at large who use our CO2 reconstructions, and of course our funders @erc.europa.eu , @ukri.org, @dfg.de and @leverhulme.ac.uk! pastglobalchanges.org/publications...

Also check out the whole special issue, there are some really great papers inside... agupubs.onlinelibrary.wiley.com/doi/toc/10.1...

We look at the history and future of d11B-CO2 reconstructions, as well as their major limitations throughout the last 70 million years. I hope this will be a great resource for boron people new and not new, students and not students! Reach out if you want to know more.

He doesn't just do the lab either, he's happy to brave the waves and come help us sample in the field. Go Maxime! (Here in the middle of the Atlantic, May 25)
