The joint ICTP-EAIFR-IUGG Workshop on Computational Geodynamics: Towards Building a New Expertise Across Africa is now open for registration and abstract submission! Katz is a speaker https://indico.ictp.it/event/10183/overview. The meeting will be held in Kigali at the Univ Rwanda.
It’s been a while #ScienceTwitter but check this video I made on small-scale convection beneath a mid-ocean ridge. Ridges are still surprising! @foa_lab @EGU_GD @OxUniEarthSci #Geodynamics #MagmaDynamics
Do faith-based extrapolations of olivine rheology from lab to mantle conditions concern you? Ever wondered why n=3.5? A new paper by Tom Breithaupt models the dislocation physics to parsimoniously explain olivine transient and steady creep, and more. https://www.pnas.org/doi/10.1073/pnas.2203448120
Three PhD projects are advertised for collaborative research in the FoaLab. For more information about Oxford graduate admissions please see https://www.earth.ox.ac.uk/teaching/graduates/graduate-admissions/. Contact Richard Katz with questions.

Clusters of subglacial seismicity are interpreted as evidence for 'sticky patches' at the ice–bed interface, even where subglacial water pressure is high. PhD student Hanwen Zhang has shown that sticky patches also promote and localise basal crevassing. https://doi.org/10.1017/jog.2022.75
Mid-ocean ridges have cross-axis asymmetry; explanations have been unsatisfactory. A new publication by @AdinaPusok et al. shows that chemical (density) fractionation by melt segregation can amplify convection, break symmetry and explain observations. https://doi.org/10.1093/gji/ggac309
