We are all studying geodynamics, but what does that really mean? Do we limit ourselves to the mantle? The lithosphere? The equations we solve? In this Wit & Wisdom post, Colin Hardy, PhD student in fluid dynamics at the University of Leeds, United Kingdom, makes his case for an often forgotten boundary condition of mantle geodynamicists: the core. Let us start with the basics and break down th ...[Read More]

The Sassy Scientist – EGU GA 2020 RIP: MTFBWY

Tokío’s contract is about to expire. Confident she would convince someone to hire her through expert presentations, astute questions, insightful discussions and uncanny charm, she now frets: I was counting on networking at the EGU GA to find a new job, but now I can’t. What can I do? Dear Tokío, I’ve got a bad feeling about this. Don’t trap yourself in a panicking fit just ...[Read More]

Plume-induced subduction inititation?

This week in News & Views, dr. Marzieh Baes from GFZ Potsdam introduces us to the mechanisms behind subduction initiation. Moreover, she discusses the different types of subduction initiation in reaction to plume-lithosphere interaction that she observed in her recent 3-d numerical modelling study. Possible scenarios of subduction initiation According to plate tectonics, oceanic plates are for ...[Read More]

The Sassy Scientist – Sharing Secrets

During the umpteenth conference call this week, it is finally time for Carrie to share her screen. So, naturally, she asks: Where is the share screen button? Dear Carrie, I am not sure how to break this to you. Indeed, I am not sure if I should be the person telling you this. However, since you ask, I feel obliged to divulge this secret to you. Just promise me you will not tell anyone. Okay? Do I ...[Read More]
