Subduction zones are dynamic regions where intense geological processes like earthquakes, volcanic eruptions, and the recycling of oceanic crust are constantly at play. A key factor that influences the behavior of these zones is *interface rheology*—the strength and viscosity of the boundary (the interface) between the subducting and overriding plates. Understanding this interface is crucial for i ...[Read More]

From ‘real life’ to a fantastic quirky teaching tool – try a PodCast Class
A giant microphone sits a few cm’s from my face. I am having vivid flashbacks to pre-show jitters and stage-fright from my earlier forages into on stage productions. Only now I’m an adult, an expert, a scientist. Our host pushes the record button. Live radio! A brilliant (?) idea takes shape I was contacted by a Norwegian scientific radio programme, Abels Tårn, and asked if I could answer question ...[Read More]

Holding it in (the learning, not the pee) – The gendered importance of toilet breaks for geoscience students during field-courses
Field-based teaching is a cornerstone of geoscience education. Concepts such as scale, complexity, spatial awareness, 3D geometries, methods, skills, and techniques are inherently difficult to teach from a lecture theatre. However, achieving the benefits of field-based teaching might require a learning module not always considered as a prerequisite: planning and providing information about bathroo ...[Read More]

Crossing borders – Glacier fieldwork at Sulitjelma/Salajekna
The time I first set foot at the university, I didn’t expect that two weeks later I would be looking at a backpack more than half my size, turning my back to the shelter of our rental car and walking almost 100 km in the Norwegian Arctic. Howling winds, heavy backpacks, daunting bridges, and endless beauty – that’s how I would describe my first experience with glacier fieldwork. I, Silje Waa ...[Read More]

DYNAMICE: An ERC Starting grant project to bridge the gap between geodynamics and ice modelling
In the 2024 ERC Starting Grant call, the European Research Council received nearly 3,500 proposals, of which approximately 14% were awarded funding. Among the 20 projects funded in the field of Earth System Sciences is DYNAMICE, led by Ágnes Király, the 2023 recipient of the EGU GD Division Outstanding Early Career Award. Through this blog, Ágnes will introduce us to her project. The vast ice shee ...[Read More]

Drilling on world’s rooftop – the Nam Co-ICDP campaign on the Tibetan Plateau
International Scientific Continental Drilling Program (ICDP) campaigns may lead scientists from all over the world to most exciting places that are often of extraordinary beauty and remoteness. All these attributes certainly apply to Lake Nam Co situated at an altitude of 4700 m above sea level on the Tibetan Plateau in the Himalayas. Today this area supplies one third of the humankind with fresh ...[Read More]

Was that a meteor or a re-entry ? The final frontier for satellites when their mission ends
Like humans, satellites have a lifespan. These machines orbiting high above Earth serve various critical purposes that range from monitoring weather systems and tracking greenhouse gases to studying the cosmos. But even the most advanced satellites reach a point when their electronics wear out, their fuel depletes, and their missions come to an end. When their time is up, what becomes of these tir ...[Read More]

Mapping the Future of Freshwater: An Interview with Niko Wanders on the World Water Map Project
Back in 2022, two hydrologists and water resources specialists from University of Utrecht launched the World Water Map in collaboration with the National Geographic Society and ESRI. Based on the outputs of their global hydrological model PCR-GLOBWB, the team of Marc Bierkens and Niko Wanders map global water resources and identify the regions most at risk of water scarcity. The maps combine stat ...[Read More]
