Exciting Bermuda Day 3 for our @oxuniearthsci.bsky.social undergrads on board the RV Atlantic Explorer with expert guidance from @stannescollege.bsky.social + Earth Sciences alumna Eloise! Sampling and processing water from down to 3500 m depth in the subtropical Atlantic.

@oxuniearthsci.bsky.social 2025 Bermuda trip is complete! We were super lucky to see a trichodesmium bloom in the Sargasso Sea and sampled an anoxic layer in Harrington Sound (usually fully mixed at this time). Bermuda is a perfect location to bridge modern and paleo ocean-climate processes!

We've had an amazing two days welcoming visitors from far and wide to the Department as part of the University of Oxford Open Days. It was a joy to meet so many brilliant aspiring geoscientists and their families!

.. delighted to see recognition for Hugh Jenkyns (@oxuniearthsci.bsky.social) who published his first paper in 1967, discovered Ocean Anoxic Events in the 1970s, and is still publishing papers on the Jurassic today!

New research has shown rivers release ancient carbon dioxide into the atmosphere, uncovering a greater role for plants and soil in the carbon cycle 🌱 Featuring @profbobhilton.bsky.social‬ Read the full story: buff.ly/yv82d3X

Fantastic day @oxuniearthsci.bsky.social doing a sedimentary journey through the Triassic and Jurassic! Oo-tastic @drsturobinson.bsky.social

The #EarthSciences are under threat at Australian universities. As Rhodi Davies and Dorrit Jacob from ANU highlight: "climate resilience, sound environmental policy and energy security all begin with understanding the planet we live on" www.timeshighereducation.com/opinion/eart...

Earth science is critical to national resilience – so why is it being gutted?

Australia must fund its universities in ways that reflect their mission – not just their margins, say Rhodri Davies and Dorrit Jacob

Lacustrine ooids and coated grains (mainly ostracods) from the Eocene Green River Formation, UT (USA). #ThinSectionThursday

The isle of Rùm and its layered intrusion remain undefeated for thin sections. Foliated troctolite (ol+plag) or 'allivalite' from Hallival, in the NMS rock collection. #ThinSectionThursday

Some excellent sedimentary structures at the junction of Cecil St and Peel St in Derby courtesy of the burst water main. Thanks to Severn Trent for the 3 day experimental run. #Streetsedimentology

New post on Mary Lyell - one of the least-known pioneering Earth sci women despite her deep involvement in husband Charles Lyell's life and science and their network of geologist colleagues, including Darwin, Agassiz, Murchison, et al. www.geological-digressions.com/mary-lyell-1... ⚒️🧪

Mary Lyell (1808-1873)

Mary Lyell, wife of Charles Lyell, was an accomplished geologist and conchologist although her place in history is relatively obscure.

🌊 🧪 The belts and escalators represent the organized flow of water, and the wandering of the people is the turbulent mixing superimposed on this organized flow. Although not perfect, this analogy does capture the important factors influencing the distribution of nutrients in the sea. -

Microbialites (sedimentary buildups formed by microbial activity) were very common in the Proterozoic, but other groups took over in the Phanerozoic. But when the environment is stressed, they come back - and we can use them to infer on past stress gradients. 🧪⚒️ www.sciencedirect.com/science/arti...

For anyone who is interested, a very brief explainer of what’s going on with historic church buildings: Church of England listed buildings are exempt from listed building controls, because the CoE has its own strict rules. The general council now proposes to bypass those rules.🧵
