Save the date mineralogists, it’s gonna be a good one!

Surprisingly good view of the partial eclipse in cloudy Cumbria 🌥️

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

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!

New year and some big personal news! 🥳

In March I will be joining the University of Stirling as a lecturer in Earth and Environmental Chemistry. I can’t believe how lucky I am to get to set up a research group in such a beautiful place, finally returning (almost) to where I grew up after 20 years!

Your cat is the antithesis of my cat

The starlings never fail to impress.

Geochemical signatures of hot ash in cold water — NERC GW4+ Lead Supervisor: Pete Rowley Project keywords: Volcanic ash geochemistry oceans

I like this one: www.nercgw4plus.ac.uk/projects-202...

There's a brilliant biogeochemist on it too :D

Haha sorry Pete! 😆

I'd particularly like to highlight this project: www.bristol.ac.uk/media-librar... I would do it myself if I could ;) it will combine heritage science, biogeochemistry, engineering, and the SS Great Britain are a great project partner!

Deadline for GW4+ PhDs with us at @bristolvolcanology.bsky.social is less than a month away. If you're interested in applying please reach out to the project supervisors ASAP. www.bristol.ac.uk/earthscience...

Low molecular weight organic acids stabilise siderite against oxidation and influence the composition of iron (oxyhydr)oxide oxidation products Siderite (FeCO3) is an important reservoir of mineral-bound ferrous iron in non-sulfidic, reducing soils and sediments. It is redox sensitive, and its oxidation may facilitate the reduction of a range...

It’s been a while since I was active here, but I’m back yay with a plug for a new paper: pubs.rsc.org/en/content/a... When I first worked on this I didn’t understand why my very air sensitive siderite wasn’t oxidising in some tests, we show that it was being stabilised by organic acids.

Finally jumped ship from the bad place 👋👋
