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]
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]
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]
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]
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]
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]
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]
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]
A frozen lake can be more than a layer of ice. It can become a road, a fishing ground, a place of spiritual significance, or a window into a changing climate. From the ice-covered waters of the Northern Hemisphere to Patagonia, lake ice shapes ecosystems and influences communities. But as temperatures rise, lake ice is …[Read More]
A question with no single answer Imagine you are responsible for the water supply of a small town in the hills. Your wells tap groundwater, fed by rain and snowmelt seeping slowly through soil and rock. One day the town council asks a simple question: Will there still be enough water in August, fifty years …[Read More]
