Hello Martin! Welcome to GeoTalk. Could you briefly introduce yourself to our readers? Dear EGU Community! My name is Martin, and since 2004 I have had the honour of being the Managing Director of Copernicus. By training, I am a hydrologist, but even before I graduated, I was drawn into the EGU General Assembly in …[Read More]
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]
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]
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]
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]
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]
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]
Here is a great resource for anyone working on ocean carbon: Jiang et al. (2026) compiled a comprehensive synthesis of data products for ocean carbonate chemistry — all in one place for you! The paper provides a comprehensive synthesis of 68 existing ocean carbonate chemistry data products and data product sets, including: 🛳️ Cruise-based Compilations …[Read More]
“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]
“I am forced into speech because men of science have refused to follow my advice without knowing why. It is altogether against my will that I tell my reasons for opposing this contemplated invasion of the antarctic—with its vast fossil-hunt and its wholesale boring and melting of the ancient ice-cap —and I am the more …[Read More]
