Beyond Navigation: How GNSS Reveals Earth’s Hidden Secrets

Beyond Navigation: How GNSS Reveals Earth’s Hidden Secrets

Part 2 – the regional case In our previous post, we discussed global scale phenomena, showing how the Global Navigation Satellite Systems (GNSS) constellation is the ultimate instrument for monitoring the Earth as a whole: tracking plate tectonics, defining the planet’s absolute size, and measuring variations of its gravity field. Essentially, the big questions of …[Read More]

A Free Tool That Maps Ancient Coastlines Like an Expert

A Free Tool That Maps Ancient Coastlines Like an Expert

by Julius Jara Muñoz, Professor of Engineering Geology at the University of Applied Sciences Biberach (Hochschule Biberach), Germany. Email: jara@hochschule-bc.de, website: https://www.hochschule-biberach.de/kontakt/julius-jara-munoz. “Reproducibility is a cornerstone of the scientific method, yet measuring ancient coastlines has long depended on expert judgment – until now”. Coastlines are highly dynamic systems controlled by sea-level changes and surface deformation. Over thousands …[Read More]

What’s up for geodesy during the upcoming EGU26?

What’s up for geodesy during the upcoming EGU26?

It’s this time of the year again when we all meet up in Vienna and talk about our latest scientific results and, more importantly, network with old and new colleagues. The EGU General Assembly (GA) EGU26 will take place again in a hybrid format. The scientific programme consists, as usual, of oral and poster presentations, …[Read More]

ECS Spotlight: When “Day Zero Drought” Dries the Tap: How Drought is Reshaping Water Scarcity in the Anthropocene

ECS Spotlight: When “Day Zero Drought” Dries the Tap: How Drought is Reshaping Water Scarcity in the Anthropocene

Extreme events are becoming increasingly observable, intense, and interconnected. Drought, traditionally viewed as a regional and temporary phenomenon, is now undergoing a fundamental shift.  We introduce the concept of “Day Zero Drought” to describe a threshold where water demand exceeds available supply under persistent drought conditions. This study shows that water scarcity is no longer …[Read More]
