Had a fantastic time at the European Geosciences Union mass extinction meeting presenting our d11B record from the Triassic-Jurassic boundary, super exciting to see all the amazing research going on in the field, thanks to the organisers for a great meeting!

Hundreds of staff and students join people from across our community for the St Andrews Students' Association 'line in the sand' event as part of the global #ClimateStrike for #ClimateAction with Greta Thunberg #evertoexcel

Its heartening to see this amazing turnout. Draw a line in the sand, >1000 staff, students, school kids, nursery children, families, grandparents etc. Climate change is real, and needs to be a priority #ClimateStrikes #ClimateEmergency #schoolstrike4climate #GlobalClimateStrike

A while ago I made some instructions on how to run for trace elements and gave it a fairly boring title, today I found out @geochemjess has renamed them something much more appropriate

Big week in The STAiG Lab begins, with magnet hoisting 🧲 and a game of hide the mass spectrometer

Moving on to past ocean acidification by Molly Trudgill at IAPETUS DTP meeting

If you're at #Goldschmidt2022 I'll be sharing the first look at our Ordovician-Silurian boron isotope record at 10:15HST/21:15BST and talking about what it tells us about ocean pH and atmospheric CO2! conf.goldschmidt.info/goldschmidt/20…

.Molly Trudgill has some of the COOLEST hot-off-the-press paleoceanographic data— check out her #Goldschmidt2022 talk 🤩

So excited to have submitted my thesis yesterday 🙌🎉 thanks so much to so many fantastic supportive people who helped make it happen (including of course, big thank you James Rae )

If you're at #icp14 I'll be at poster P1-107 this afternoon sharing what we've learnt about ordovician carbon cycling from boron isotopes

🚨Exciting new work to share by Sophie Nuber as part of her @CU_Earth Earth & Environmental Science, St Andrews PhD!🚨 Sophie shows the glacial Indian Ocean gets super salty, due to sea level-restricted Indonesian Through Flow, and that this salt may help deglacial AMOC recovery nature.com/articles/s4158… 1/n🧵

So excited to share the latest on our work using boron isotopes to understand major environmental change in deep time in a couple of weeks! Link to register below if you're interested in coming along 😊

Nitrogen is likely not a volatile element in all magmatic systems 🌋 One of my PhD chapters is out today in Nature Geoscience! rdcu.be/ddxxd We show nitrogen in a cogenetic magmatic system most closely follows lithophile trace element behaviour (similar to Rb)

Just released my latest paper about the 'peri-column' on G-cubed! Introducing a new boron purification technique using pumped ion-exchange column chromatography. Cut down the process to 1.5 hrs for 12 samples🚀and limited TPBs to ~ 10pg B! #boronisotope agupubs.onlinelibrary.wiley.com/doi/10.1029/20…
