Using depth-dependent clustering analysis of global Vs and Vp tomographic models, we have constructed a new reference model for LLSVP shape and volume. We obtain new, much larger estimates of the volume/mass occupied by LLSVPs—8.0 % ±0.9 (μ ± 1σ) of whole mantle volume and 9.1 % ±1.0 (μ ± 1σ) of whole mantle mass. We also […]

This month, Anthony Mautino obtained his MS in Geology with a thesis about characterizing spherical Couette flows with acoustic normal mode splittings. Here, we are gathered to celebrate Anthony’s achievement, as well as bid farewell to Andrew Eagon who was a summer intern in the lab from Wisconsin, Whitewater.
Congratulations to Anthony Mautino Read More »
REM-3D is a project funded by the National Science Foundation and carried out by Raj Moulik, Ved Lekic, Barbara Romanowicz, and Adam Dziewonski. If you have questions, please do not hesitate to contact us. You might find the answer you are looking for in our new FAQ section. The aim of the project is to develop a three-dimensional

Together with collaborators Max Rudolph at Portland State University and Carolina Lithgow-Bertelloni at University College London, we used a novel inversion framework to detect the presence of an increase in viscosity in the Earth’s mid mantle. As Science magazine put it: A mysterious mid-mantle slowdown The viscosity of Earth’s deep interior plays a key role
