Geodynamic modelling helps us understand Earth’s internal processes by providing a framework to test hypotheses. Analogue modelling uses physical models governed by the laws of nature, with resolution down to Planck’s length. In contrast, numerical modelling employs mathematical methods to approximate solutions to the physical laws governing Earth’s processes. Each modelling approach comes with it ...[Read More]

Biogeodynamics – Let’s model the entire world!

Timothy Gray and edited by Betti Hegyi May 15, 2024

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]

Dihydrogen (H2) is a promising source of energy that may allow reducing carbon emissions in industry and transportation. Artificial production methods have been explored, natural sources of H2 (also called white dihydrogen) offer a more eco-friendly and cost-effective production process. In this week’s blog post, Alexis Gauthier, a PhD student from ISTeP, France, is discussing the H2 production pr ...[Read More]

Geoscientists explore the nature from a different perspective than the commoners. In this week’s blog, Stephanie Sparks from Arizona State University shares her story how her passion for mountains gradually became her profession. Her journey through different regions in Himalaya leads her to understand the exhumation rate and the underlying geodynamic processes behind the formation of world’s high ...[Read More]
