Regional viscosity variations in Earth’s mantle

Regional viscosity variations in Earth’s mantle

For understanding the dynamics and evolution of the Earth’s mantle, knowledge of mantle’s viscosity structure is very important. In this week’s blog, Kenneth Gourley from University of Arizona discusses the variation of viscosity structure in Earth’s mantle in regional scale.   In order to understand the dynamics and evolution of the Earth’s mantle, geodynamicists model mantle fl ...[Read More]

The Sassy Scientist – Funding the Abyss

The Sassy Scientist – Funding the Abyss

Has the ocean temperature risen again? Are you tired of dressing like an onion to adapt to 15 degrees of change in a day? Here we have a cooling question. Peter asks: If you had infinite funding, what would you do? Dear Peter, If I had infinite funding, you’d find me setting up my new office at the bottom of the Mariana Trench – because if you’re going big, might as well go seven miles deep, ...[Read More]

Geotandem: The Red Planet, often recognized as a dead planet, is not quite dead after all, at least geodynamically speaking

Geotandem: The Red Planet, often recognized as a dead planet, is not quite dead after all, at least geodynamically speaking

Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the same topics from different but also complementing perspectives. In each edition, we will bring you a high-interest topic for the community seen from the eyes of diverse disciplines. Today, the Tectonic ...[Read More]

H2 production associated with mantle wedge hydration in subduction zones

H2 production associated with mantle wedge hydration in subduction zones

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]
