I remember the day very well. It was the first time we drove up to the glacial ice from our base station in Kangerlussuaq (Western Greenland), where we had patiently been waiting for two days for the weather to clear. I took this photo during a three-week fieldwork campaign as part of the Deep Purple project. As part of the project, we were in the field to collect glacial ice-algae samples, whic ...[Read More]

Hydrotalks: IAHS working group leaders and coordinators on HELPING scientific decade, working groups activities, and writing community papers
In episode 8 of the Hydrotalks podcast, we hosted four coordinators of working groups of the HELPING hydrological decade. We warmly welcomed Dr. Giulio Castelli (University of Florence) and Dr. Natalie Ceperley (University of Bern), group co-leaders of Co-Creating Water Knowledge working group; Dr. Soham Adla (ING Bank, Netherlands), a coordinator of Science communication, outreach, and promoting ...[Read More]

Tuna and Tufo: The geology and history of the Aegadian Islands near Sicily
The Aegadian or Egadi islands (not to be confused with the Aegean islands situated between present day Greece and Türkiye) is a small archipelago of islands around 20 km off the Western coast of Sicily. These islands are most known for their historic industries, namely for a type of rock quarried from the largest island (Favignana) and the large tuna fishery around the island. In recent times this ...[Read More]

Under pressure: measuring stress within the crust
At the geodynamic scale, tectonic forces guide the distribution of stress. Stress in the Earth is not constant, but varies through space. Variations in gravitational energy caused by changes in mass distribution within the Earth, forces acting at plate boundaries, and basal mantle drag all cause stress to vary and act in different directions. Overall, stress plays a key role in tectonics. It allow ...[Read More]
Climate: Past, Present & Future
Inside the Baltic Sea N2O Hunt: Tracing Sources using Isotopic tools
Nitrous oxide (N2O), commonly known as laughing gas, is one of the most important greenhouse gases, and its rise in the Anthropocene significantly contributes to global warming and depletion of stratospheric ozone. The marine environment, especially coastal and marginal seas, is an important (about 25%) contributor to the global atmospheric source of N2O. Nitrous oxide is primarily produced in mar ...[Read More]

Why “Perfect” Infrared Spectrometers Are a Myth – and Why That Matters for Atmospheric Measurements
Modern atmospheric science relies on precise and stable measurements to understand how the composition of the atmosphere evolves over time. From air quality to climate-relevant trace gases, long-term observations are essential for identifying trends and detecting subtle changes. One of the key tools enabling such measurements is infrared spectroscopy, which allows scientists to identify and quanti ...[Read More]

ST-ECS Networking Campfire: “How to Mentor”
In academia, success is often measured with quantifiable outputs such as publications, grants, and awards. On the other hand, the challenging road leading to this success is not something discussed openly. The relationship we build with our colleagues, the support and guidance we receive from mentors and supervisors are important factors affecting our success as individuals and as a community. Me ...[Read More]

Is Soil Quality the same in all Conservation Agriculture Fields?
Soil degradation has become a major environmental concern. Today, 62% of European soils are affected by at least one degradation process, largely driven by land sealing and unsustainable farming practices (Mason et al. 2023; EUSO 2024). Conservation Agriculture (CA) is often promoted as a promising alternative, combining sustainable production with improved soil quality (Chabert et Sarthou 2020; T ...[Read More]

What’s blobbing inside the Earth? – insights from numerical modelling
Seismic waves tell us that something unusual is happening in the lowermost few hundred kilometers of Earth’s mantle. Beneath Africa and the Pacific lie two enormous thermochemical structures known as Large Low-Shear-Velocity Provinces (LLSVPs). These “large blobs” are slower to transmit shear waves, but beyond that, their physical nature remains one of the biggest open questions in deep Earth geod ...[Read More]
