Welcome to GeoTalk, Caitlyn and John! Could you please briefly introduce yourselves to our readers? John Hillier (Interim Division President): I have a very mixed research background. I started off in marine geophysics and then I moved to glacial geomorphology. At the end of that I worked for an insurance company as a catastrophe modeller, …[Read More]

GeoRoundup: the highlights of EGU Journals published during October!
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights section. For September, we are featuring Geoscience and Society (GS), Geomorphology (GM) , Biogeosciences (BG). They are represented by the journals Geoscience Communication (GC), Earth Surface Dynamics (ESurf), …[Read More]
Gravity – The Invisible Force Shaping Our Earth | New educational short film
How do geodesists measure gravity? And what does it reveal about our planet? Gravitation is one of the most familiar forces in everyday life, yet almost no one can explain how geodesists use it to monitor a changing Earth. A new short film from IAG’s Global Geodetic Observing System (GGOS), “Gravity – The Invisible Force …[Read More]
Halloween nightmares: haunting tales of data gone missing
One major pillar of science are datasets. Collecting, analysing and understanding data is basically what research is all about. In this blogpost, Claire Treat tells a story about haunting data experiences that researchers from other fields can relate to for sure. In honour of Halloween, I decided to regale the good readers with spooky, haunting …[Read More]
Which rain and temperature should drive your model? A guide to select daily forcing datasets , with application to northern Italy
If you want to run a hydrological model anywhere, the first question is which meteorological forcing to use. For the Po basin, or anywhere in northern Italy, there are today at least a dozen gridded products, regional and European, built from different meteorological networks, with different methods and for different purposes. I reviewed them from …[Read More]
Cooling glaciers in a warming world?
Small glaciers are often written off: too small to matter, and soon gone anyway. Yet recent disasters in the Alps show that they can still pose a threat. And some are doing something rather unexpected: while the climate warms, the ice inside them has turned cold. We drilled into six small Swiss glaciers to find …[Read More]
The Breathing Ice Sheet: How Antarctica’s Changing Ice Moves the Ground Beneath It
In this week’s blog, Dwijendra Pandey, a PhD student in the Tectonic Geodesy Group at CSIR-NGRI, Hyderabad, India, takes us beneath Antarctica’s ice to explore how changes in ice and snow move the solid Earth, and how scientists track this subtle motion from space and on the ground. Antarctica might seem like the last place you …[Read More]
Unraveling Low-Latitude Ionospheric Delays: How Solar Flux and Energetic Protons Shape Storm-Time TEC Across Solar Cycles 23–25
Introduction Geomagnetic storms present a constant challenge to global navigation satellite systems (GNSS), driving space weather researchers to better understand how the ionosphere responds when solar drivers strike. A primary key to this puzzle is ionospheric delay time, the exact duration between the onset of a geomagnetic storm and its peak impact on the Total …[Read More]
From Fault Architecture to Grain-Scale Deformation: Integrating Field, Microstructural, and Experimental Approaches
Fault zones are far more complex than the lines we draw on geological maps. Their internal structures, mineralogical compositions, and deformation histories offer important clues to deformation mechanisms and even how earthquakes might occur. But how can we connect what we observe in the field with the microscopic processes and mechanical behaviour of faults at …[Read More]
Habitability in the Solar System and Biomining: From extremophiles to space resources
Hello readers! We’re thrilled to announce the new campfire event of the EGU planetary and Solar System Sciences (PS) Division dedicated to astrobiology, habitability in the Solar System and biomining. Our guests will be Joseph McNeil (Natural History Museum of London), Adrienne Kish (National Museum of Natural History of Paris) and Luca Tonietti (University of …[Read More]
