Mid-ocean ridges (MOR) and hotspots are two types of magmatic activity occurring in the ocean. The MORs are typically associated with another tectonic feature—oceanic transform faults. While numerous studies have focused on the interactions within MORs, hotspots, and transform faults, there has been limited research on cases where a hotspot and a transform fault are located at the same end ...[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]
