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 🌱

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

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked,

"If they raised the Mary Rose, why not raise the Titanic?"

Allow our scaled diagram to explain...

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
Just one of the best thin section images you're likely to see. Brightly coloured fresh olivines in blues, yellows, and oranges among smaller black, white and grey plagioclases, which generally define a fabric from left to right.

#fossilfriday a shell bed in the Purisima Formation at Capitola, northern CA coastline, early Pliocene (4.9-5.3 Ma). Many of the shells retain much of their original coloration!
Fossil mollusk shells with some of their original coloration in a shell bed in a boulder on the beach in Santa Cruz CA. A rock hammer is there for scale. The shells are between 1 and 8 cm in width.

An neat write up of what may have caused the planet covering glaciations between 720 million and 635 million years ago based on a geologically constrained global plate model: large-scale shut down of oceanic spreading centers decreases CO2 release.
(Figure from link.)

Image from linked write up on the Cryogenian glaciations and Earth's tectonics showing the configuration of continents and oceanic crust of different ages (from dark (oldest) blue-black to light (youngest) blue-white) based on a geologically constrained model (left) and a paleomagnetically constrained model (right). The continents are somewhat different but the oceanic crust's age is extremely different. The left image shows mostly old oceanic crust while the right image shows a large amount of young oceanic crust.

🌊 🧪 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. -
