Super excited to see this published in the home of diamond open access seismology! Across the full workflow (writer, reviewer, handling, copy) @weareseismica.bsky.social is fantastic!
Want better surface wave tomography?

Jack Muir describes how Gaussian Processes benefit tomography imaging processes and deliver robust uncertainty measurements.

It’s the end of my first week at Fleet Space - really interesting and invigorating to see things from the industry perspective. I’ve certainly learnt more this week than the early days of my PhD!

Gas properties of toys:
- They expand to fill available space
- pressure (on your feet) and volume inversely correlated
- sometimes the thermodynamic demons only care about the partial pressure of Lego

Joyfully experiencing one last Oxford tradition (having your bike stolen in Michaelmas term) before I head back to Aus! From international, to national, to personal, a wonderful week all round…

In Australia, the absence of relief in the interior means that the timescales of groundwater flow can be even older ... maybe even millions of years.

And, interestingly, this means that tilting due to dynamic stresses from the mantle may influence the flow patterns.
Ancient groundwater: Why the water you're drinking may be thousands of years old
As surface water diminishes in the Western US, people are drilling deeper wells – and tapping into older groundwater that can take thousands of years to replenish naturally.

How can we map anomalies on the core-mantle boundary nearly 3000 km deep?
@CarlMartin_
presents a fresh Bayesian methodology and its application to the anomaly at the base of the Hawaiian mantle plume and a 2-part paper.

Signed - the Tories desperate attempts to manufacture a wedge have no place in scientific society.
✉️ Some science 🧪 buddies and I have written an open letter to the UK government, strongly opposing their “kicking woke ideology out of science” sentiments, which stand to damage the UK’s scientific standing and ability to deliver for public good.
