Mars’ lost oceans: Inside the new planetary hydrology model published in EGU’s Geoscientific Model Development (GMD)

If we look at Mars today, we’ll see a cold, dusty desert, but peel back the surface geology, and the planet tells quite a different story! Networked river valleys, ancient deltaic fans, carved impact crater lakes, and potential palaeoshorelines all point to a warm and active past during the Noachian and early Hesperian epochs, circa 3.7 to 4.1 billion years ago. For decades, planetary scient ...[Read More]

The giant seafloor sponge: how water ends up in subducting crust

The giant seafloor sponge: how water ends up in subducting crust

In this week’s blog post, Daniel Douglas teaches us everything about poroelasticity, water in subduction zones and… sponges under the sea! Are you ready kids? Aye, aye, Captain! Why study subduction zones? “Subduction” is a process that occurs when two tectonic plates collide with each other. As long as one of the plates is an “oceanic plate”, then the denser of the two tectonic plates ...[Read More]

GMPV-PS Campfire: Rocks across the Solar System: From planetary differentiation to surface processes

What can meteorites tell us about Earth’s environment? How do minerals record a cosmic collision? And could Venus be hiding lava tubes? Our joint GMPV–PS Campfire brings together four talks exploring these questions and the early differentiation of Mars, plenty of planetary ground to cover! From environmental and shock processes preserved in chondrites to the formation of planetary crusts and the ...[Read More]

A Remote Sensing Solution for Nitrous Oxide: The Greenhouse Gas We Need to See Better

When we talk about greenhouse gases and climate change, carbon dioxide (CO2) and methane (CH4) usually receive most of the attention. Yet another gas, nitrous oxide (N2O), quietly plays an important role in our changing climate. Commonly known as “laughing gas”, N2O is a powerful greenhouse gas with nearly 273 times the warming potential of CO2 over a 100-year period. Once released, it can remain ...[Read More]

Next-Gen Computing in Geosciences: High-Performance Computing, AI, and Quantum Frontiers

and October 2, 2026

The Earth is an intricately coupled system, and simulating its behavior (from volcanic eruptions to global climate shifts) requires immense computational brute force. For decades, computers have been the quiet backbone of geosciences. Today, however, we stand at a major inflection point. High-Performance Computing (HPC) is pushing the boundaries of high-resolution simulations, while emerging techn ...[Read More]

Meet the Snow Dunes of Antarctica

By Marine Poizat, PostDoc at the Geological Survey of Finland. Email: marine.poizat@gtk.fi, website: https://www.gtk.fi/en/experts/poizat-marine/. Antarctica has dunes. And they are made of snow. When people think of deserts, they usually picture vast expanses of sand beneath a blazing sun. Yet Antarctica is also a desert, receiving remarkably little precipitation, especially inland. And like othe ...[Read More]

“State of the ECS”: EGU 26 and, our new members!

For this “State of the ECS”, our Seismo-team will introduce themselves and tell about their ECS experience. Happy reading! Greetings! I’m Adam and by a twist in the timestream in Vienna in 2024 I ended up as the Editor-in-Chief of a blog of the Seismology ECS division (yes, this one). If your (or your colleague’s) research touches on any aspect of Seismology or related fields, please reach o ...[Read More]

EGU Campfire Geodesy – Share Your Research – 23rd Edition

We are excited to announce the 23rd edition of Geodesy Campfire – Share Your Research in October. The Geodesy EGU Campfire Events “Share Your Research” give (early career) researchers the chance to talk about their work. We have two exciting talks by our guest speakers, Saqib Mehdi and Laura Giaccio. Below, you can find the details of the topics awaiting us. We will have time to network after the ...[Read More]

The Sassy scientist – Where are the disabled geologists?

  Dear Sassy Scientist, In my institute I never see any disabled people. Only one or two people in wheelchair at the EGU GA. Considering the statistics in the global population, I’m sure some people are impared, but tell me : Where are the disabled geologist ? Is it impossible to be disabled and geologist ? Your gnocchie Dear gneiss human, Thank you for putting light on this question. To answ ...[Read More]
