Biogeodynamics – Let’s model the entire world!

Biogeodynamics – Let’s model the entire world!

All models are wrong, but some are useful – we all have heard this quote. But it raises several questions (including but not limited to) – What would a model of the entire world look like? Can you couple geodynamical models with climate and biological evolution models? Would these models be useful? In this week’s blog post, Timothy Gray, a PhD student from ETH Zürich is looking for ans ...[Read More]

Modelling CPO evolution with D-Rex

Modelling CPO evolution with D-Rex

As a result of Earth’s mantle convection, rocks in the earth’s interior flow and develop a crystallographic texture. These textures reveal the planet’s thermal and tectonic history and are responsible for the viscous anisotropy, which can be used to study the planet’s deeper recesses that are not visible through other means. This necessitates the use of models that can pred ...[Read More]

Into the anisotropic Earth

Into the anisotropic Earth

While we have sent several rovers to Mars, drilling down even just to the mantle of our own planet is a challenge that we are yet to overcome. How is it then that we know all these things about our planet’s interior? It turns out, we do not need to be inside the Earth to know what is happening there. Observations from geophysics and geochemistry can inform us about the processes and the properties ...[Read More]
