Very excited to share the culmination of a 5-year journey, now published in @nature.com. We built the first-ever 3D attenuation model for the whole mantle! This was a collaboration between @uugeo.bsky.social, @mitpress.bsky.social and @vassar.bsky.social!

Here, we used the first whole-mantle 3D attenuation model to interpret the longevity & viscosity of the large low velocity provinces (LLSVPs). To explain our observations the #LLSVPs need to be not only hotter but also have larger mineral grains, in contrast to their surroundings

Great new Nature paper from my Utrecht seismology colleagues on the physical properties of the enigmatic LLSVPs!

Global 3D model of mantle attenuation using seismic normal modes - Nature
Using whole-Earth oscillations to constrain a 3D global model of attenuation for the whole mantle, low attenuation correlates with low velocity in the lower mantle, suggesting long-lived deep-man...
