Inside the Baltic Sea N2O Hunt: Tracing Sources using Isotopic tools

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

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?

March 4, 2026

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

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]

EGU Campfire Geodesy – Share Your Research – 17th Edition

We are excited to announce the 17th edition of Geodesy Campfire – Share Your Research in February. The Geodesy EGU Campfire Events “Share Your Research” give (early career) researchers the chance to talk about their work. We have two exciting talks by our guest speakers, Hugo Lecomte and Marius Schlaak. Below, you can find the details of the topics awaiting us. We will have time to network after t ...[Read More]

On the correlation and interactions of space weather with biological indicators

On the correlation and interactions of space weather with biological indicators

1. Introduction Space weather is significantly affected by geomagnetic disturbances (GMDs) that occur during or after intense solar events such as coronal mass ejections (CMEs), which expel substantial amounts of electromagnetic particles into interplanetary space. Most of these particles collide with the magnetosphere (the outermost region of the atmosphere) where the solar wind (continuous flow ...[Read More]

IGS: A Home for the Global Cryosphere

Like many glaciologists (in the broad sense – as in, cryospheric researchers, not just those who study glaciers!), my professional “home” has been the International Glaciological Society (IGS) ever since grad school; My first conference was an IGS branch meeting, I found my postdoc by networking at an IGS symposium, I have published work in IGS journals, and IGS has supported many community activi ...[Read More]

Bits and Bites of Geodesy – Satellite Gravimetry: Studying Earth’s water cycle from space

During winter, mountains gain mass because of snow covering the peaks. In spring, the snow melts and flows downstream until it reaches the ocean or evaporates into the atmosphere to reach back on the surface as rain or snow. The global water cycle is very complex and essential for life on our planet. Did you know we can measure how the water is distributed by measuring its mass from space? How can ...[Read More]

FrenSZ workshop: a French interdisciplinary initiative around subduction zones.

Since 2022, the annual FrenSZ workshop has been bringing together a vibrant and interdisciplinary community around subduction zones in France. In this week’s blog post, we dive into how FrenSZ is organized, highlight its scientific outcomes and how it is opening new connections on the international stage. A large French community. In France, a fairly large community of Earth Scientists devote thei ...[Read More]
