Still a week left to apply for this PhD opportunity @bas.ac.uk, working on palaeoecology of #Antarctic marine ecosystems in the #Eocene (deadline 13/1/25). Please get in touch if you're interested and want to know more about the project or the application process!

Artists rendition of the death of the Late Palaeozoic Ice Age from this great paper by Hana Jurikova @mudwaterclimate.bsky.social and others (www.nature.com/articles/s41...). The papers also contains some lovely boron isotope data tracing CO2 300 million years ago! 🧪⚒️🌊

Come do a PhD with us at Bristol! Looking for a student to look at B incorporation into silica - both experimentally-precipitated and biogenic.. With @krhendry.bsky.social @sophwestacott.bsky.social and Franziska Stamm. Deadline Monday 13th of January! DM or email me for more details. bit.ly/3W8WshH

There are more than 10m children in school in the UK…but, per Times, 3,000 might move to state sector because of VAT rise…so Whitehall is “braced” 😲😲😲 Says a lot about UK media bubble, the way this story is reported. You pay VAT on luxuries. Private schooling is that.

Taphonomy of organelles and the origin of eukaryotes with @phil-donoghue.bsky.social @jameswclark.bsky.social @tweethinking.bsky.social Davide Pisani, John Cunningham [NERC GW4+ Jan 13] Ground-truthing the boron isotope-pH proxy in biogenic silica with @michaelhenehan.bsky.social [NERC GW4+ Jan 13]

Back in Villefranche! Reunited with our lovely hosts. First day plankton sampling today- wish us luck (or more specifically lots of radiolarians!)

The first paper from my student Simon Ring's PhD thesis is out now! He quantifies boron partitioning and isotope fractionation during adsorption onto different clay minerals.. refining the mechanisms for how it works and what it means for global B fluxes. doi.org/10.1016/j.gc...

🦖I'm readvertising a PhD project at Bristol applying B isotopes to Cretaceous Ocean Anoxic Events as part of the @petrarch-project.bsky.social . Deadline April 12th, starts mid-September. See www.bristol.ac.uk/media-librar... for details! RTs (or RBSs?) appreciated.

2nd PhD project within the Petrarch project still open- deadline 14th Feb.. come work within a lovely team to figure out how large igneous provinces and maybe the biological pump interacted to drive Cretaceous OAEs.. www.petrarch-project.science/join-us

🚨2 geochemistry positions 🚨 in beautiful St Andrews(1 postdoc, 1 lab tech) studying volcanic forcing of climate. FWIW I am definitely better at science & supervising than social media!👩🏻‍🔬 Deadline extended Jan 10. tinyurl.com/29c6ebxc & tinyurl.com/mpd7tphh

Loads of PhD openings, some with me, some not (a thread 🧵)- please spread the word (🙏). First is a @PETRARCHproject one with me at @UoBEarthScience , open to all nationalities, working on the causal drivers of Cretaceous OAEs with boron isotopes bit.ly/petrarch2 . . 1/7

Wow, seems like I'm late to the party.. what have I missed? Not a great URL - evokes Murdoch BSkyB..
