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]

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]

Climate: Past, Present & Future

Winds of change – How can we reconstruct the directions of winds in the past?

Winds of change – How can we reconstruct the directions of winds in the past?

Invited guest from the EGU 2025 Outstanding Student and PhD candidate Presentation (OSPP) Award Wind is not easily visible. On historical time scales, its directions and velocities have been measured and recorded by instruments. To some degree, these parameters can also be simulated by climate models. But how about winds in the more distant past? …[Read More]
