On the contemporary front; semi-mainstream but definitely stuff by Lankum & Mitski if you don’t have it already. Classical is so hard when the recording makes such a difference! As an Australian maybe I can plug something by Peter Sculthorpe or Elena Kats-Chernin.

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!

Maybe we can revise the code upwards to account for Lucy Jones’ functional recovery standard and end up cancelling everything out!

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!

Hi Brian, I will be in Australia by then, so I will see if I can make it - it looks like a great set of speakers! Later that month I’m starting up as head of ML at Fleet Space / I’m speaking with RSES about a visiting position, so most likely will be in the ACT somewhere

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

That’s why I stick to the wave propagation side, where linear continuum mechanics gets you 90% of the way there for most things :)

Interesting! I think it’s still an open question as to what the characteristic timescale of the earthquake nucleation process is (I’m not an expert), whereas even classical weather models are often ok on the scale of hours - days…

Models for ultrafast ensembling (I.e fourcastnet) require training on physics based simulators though, so not exactly comparable as we don’t have those for earthquakes. Although there might be others in weather you are referring to that train directly on data!

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…

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.

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.

Interested to read this! (Both links seem to go to part 2 for me though?)

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.

People seem to give of themselves more here on bluesky than back in the other place β€” in that spirit, here are 3 (bad) haiku in celebration of Autumn:

Do you do only flyovers or does GNS do ground sampling as well at the moment?

Australian bird of the year 2023: vote for your favourite #birdoftheyear in the Guardian / BirdLife ...

It's #birdoftheyear Australia time once again! I'll be continuing to hold a torch for the superb lyrebird β€” cruelly underappreciated by past polls. As an adopted Canberran I won't be sad if the gang-gang carries it though...
