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

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

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 is also directly affected by surface conditions (Fig. 1). Using the eddy covariance te ...[Read More]

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

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

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 for our FLF funded ‘Urban Waterways’ project. Rivers are known t ...[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 ...[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, Pico sessions, networking opportunities, and short courses. All scientific ...[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 confin ...[Read More]

From Finland to Switzerland: A Campervan Journey for Snow Research

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 season was challenging. I’m visiting the Snow Hydrology research group in WSL Insti ...[Read More]

Podcast Launch: History of Hydrology Interviews

“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 science. Science is anarchic, it’s bottom-up.” Prof. Mike Kirkby, episode 2 “I wr ...[Read More]

At the Mountains of Madness: Lovecraft Applied for Geology (and Failed)

At the Mountains of Madness: Lovecraft Applied for Geology (and Failed)

“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 reluctant because my warning may be in vain.” The opening lines from At the Moun ...[Read More]
