Beyond Navigation: How GNSS Reveals Earth’s Hidden Secrets

Radosław Zajdel and Jan Douša April 24, 2026

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]

Beyond wind speed: what really controls air-sea gas exchange?

Yuanxu Dong April 23, 2026

When we think about what drives air-sea gas exchange (such as CO2), wind usually gets all the credit. Strong winds stir the surface, enhance turbulence, and speed up gas transfer. But a new study in Atmospheric Chemistry and Physics shows there is more to the story: CO2 exchange does not just follow the wind, it …[Read More]

Low-cost equipment keeps urban waterway greenhouse gas emissions research afloat

Liz Flint April 22, 2026

Greenhouse gas emissions from urban waterways Every field scientist knows to never go to the field without ample supplies of duct tape and cable ties. We utilised this notion daily within the University of Bristol’s Watershed Carbon Lab team, as we undertook a 2-year long field campaign across the UK, Europe and China collecting data …[Read More]

A Free Tool That Maps Ancient Coastlines Like an Expert

Julius Jara-Muñoz April 22, 2026

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

Ravinandrasana P. Vecchia April 20, 2026

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]

From Finland to Switzerland: A Campervan Journey for Snow Research

Maiju Ylönen April 17, 2026

a scientist lays on the grass with a dog in the sun. Its a casual setting with camping equipment scattered around them

Traveling by land within Europe is relatively easy, and for me it’s also a conscious choice to push back against the fast pace of modern travel and the normalization of flying. I chose to drive a van instead of taking the train mainly because of my dog, and because finding pet-friendly accommodation during the high …[Read More]

Podcast Launch: History of Hydrology Interviews

Pau Wiersma April 16, 2026

“The number one piece of advice I would give anybody is to pick a problem and go after that problem. Ideally, you should pick a problem that requires a lifetime to solve.” Prof. Siva Sivapalan, episode 1 “A lot of greybeards telling us what we should be doing is absolutely the wrong way to do …[Read More]
