Mantle heterogeneity and flow from seismic and geodynamic constraints [PDF]

, 2007
textI have developed 3-D models of mantle heterogeneity that satisfy seismic and geodynamic observations. The seismic constraints include body wave travel times of multi-bounce mantle and core shear waves.

Control of the symmetry of plume-ridge interaction by spreading ridge geometry

, 2010
The Iceland, Gal´apagos and Azores plumes have previously been identified as interacting asymmetrically with adjacent spreading centres. We present evidence that the flow fields in these plume heads are radially symmetric, but the geometry of the mid ...

Analytical solution for viscous incompressible Stokes flow in a spherical shell [PDF]

, 2017
I present a new family of analytical flow solutions to the incompressible Stokes equation in a spherical shell. The velocity is tangential to both inner and outer boundaries, the viscosity is radial and of the power-law type, and the solution has been

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Seismic Anisotropy in the Java‐Banda and Philippine Subduction Zones and its Implications for the Mantle Flow System Beneath the Sunda Plate

Geochemistry, Geophysics, Geosystems, 2020
The Sunda Plate is a minor tectonic plate bounded by tectonically active convergent boundaries, below which are subducting: the Philippine Sea Plate to the east and the Indo‐Australian Plate to the south and west. It is thus an ideal tectonic setting for

Large-scale adaptive mantle convection simulation

A new generation, parallel adaptive-mesh mantle convection code, Rhea, is described and benchmarked. Rhea targets large-scale mantle convection simulations on parallel computers, and thus has been developed with a strong focus on computational efficiency

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.
