“Bored by the Lower Mantle? Think again!” In my new @EGU_GD blog, I talk about how deep mantle dynamics can be “seen” with seismic anisotropy, revealing a lot more going on down there than we think. Enjoy and don’t get bored!😊 blogs.egu.eu/divisions/gd/20…

Bored by the Lower Mantle? Think Again!

Is the lower mantle boring? For a long time, the lower mantle was thought to be relatively featureless and uniform compared to the more dynamic upper mantle. But recent seismic observations are...

Interested in how we can use geodynamic simulations for resource exploration? ⚒️ I wrote a blog for @UCDgeodynamics, on simulating natural H2 gas resource development in nature. 😃 The blog: geodynamics.org/highlight-au… The original @ScienceAdvances paper: doi.org/10.1126/sciadv.adr34…
