“I am forced into speech because men of science have refused to follow my advice without knowing why. It is altogether against my will that I tell my reasons for opposing this contemplated invasion of the antarctic—with its vast fossil-hunt and its wholesale boring and melting of the ancient ice-cap —and I am the more reluctant because my warning may be in vain.” The opening lines from At the Moun ...[Read More]

The sassy scientist: we regret to inform you

The Sassy Scientist April 1, 2026

With the winds of change brought by a new season, I’m back to help my readers to get out from dispair. This time a reader ask: Dear Sassy scientist, How do I deal with rejection during a job hunt? Dear Sarah, I hear you writing from the edge of despair. Let’s be honest: you’ve chosen the scenic route to career purgatory. Nevermind watching your lifelong friends enjoying their permanent contr ...[Read More]

Dr. Siavash Ghelichkhan is the 2026 EGU ECS Awardee for the Geodynamics divison. Congratulations, Sia! The image in the upper-right corner is the present-day thermal structure predicted from a global mantle convection simulation in G-ADOPT (see https://gadopt.org/).

The Division Outstanding Early Career Scientist Awards highlight exceptional scientific contributions made by an Early Career Scientist in the fields of Earth Sciences associated with each division. This year, the prestigious recognition for the Geodynamics Division has been awarded to Dr. Sia Gelichkhan, from the Australian National University. Today we have the pleasure of interviewing him on hi ...[Read More]

Subduction interfaces are complicated – and that’s their beauty!

The dynamics of subduction zones are strongly influenced by the subduction interface. Understanding its rheology enables geodynamic modellers to better simulate these systems and unravel the fundamental processes that govern them. In today’s blog post, we explore subduction interface rheology and discuss effective approaches for modelling it. What is a subduction interface? I first met a subductio ...[Read More]
