We're back for a third season! And now with a new logo and 10 new episodes coming each week over the next few months.

@volcaknowledge.bsky.social has just joined #BlueSky So please give a share and a follow to help us spread the good 🌋 word!

Tomorrow we take you to country FULL of great geology!

WELCOME TO VOLCAKNOWLEDGE!

The podcast exploring how volcanoes interact with nature culture and society, featuring new guests every episode. Hosted by @smitchellscience.bsky.social

Season 3 is JUST around the corner!! 🌋 So stay tuned for an exciting first episode with some VERY famous geology...

Our researchers have discovered an unexpected change in the Southern Ocean around Antarctica.

Since 2015, it has lost sea ice equal to the size of Greenland. They found surface waters are becoming saltier, causing more melting.

If you want to know more about my latest paper on the Afar plume (www.nature.com/articles/s41...) I'm presenting it as a poster today at the IAVCEI conference.
Come chat in the poster session (#147) or just come say hello if you see me about! #iavcei2025

Thanks Ali! Hope you're well!

Delighted to see Emma Watts' cool new Nature Geoscience study (with myself, @derekkeir.bsky.social and others) on the Afar plume featured so prominently in @thetimes.com today:

Finally I'd like to draw attention that this study was the hard work of everyone involved and that it couldn't have happened without each and every one of them!
Thanks everyone! Diolch yn fawr iawn!

and others!

To see if these were then linked we did K-means cluster analysis and principle component analysis showing that not only are the rifts linked, but we see a repeating pattern of pulses spreading down both rifts! Due to the different rifting rates in both, the flow from the upwelling is different.

We tested these models on our large dataset using two-deep cross validation of linear and spline models. We found that a singular upwelling that is independent across each rift (Main Ethiopian Rift, Red Sea Rift, and Gulf of Aden Rift) fit best

Following this we combined the geochemical data with geophysics data using statistical methods.

Then we tested previously published models of what the Afar plume looks like in the upper 120 km of the Earth. This included testing for a singular upwelling, plumelets and heterogeneous upwelling(s).

Our study started by gathering new geochemical data from >130 volcanic rocks across the Afar triangle, improving the spatial resolution of data.

Some of these rocks were collected during fieldwork and others were obtained from the Afar Repository at the University of Pisa @sorcerinsar.bsky.social

New paper alert🚨

In this new article in @natgeosci.nature.com we use a multidisciplinary approach (geochemistry, geophysics and mathematically modelling) to see pulsing in the mantle plume beneath Afar and how the flow varies along the rift See the 🧵 below:
