EGU NP Paper of the Month “Finite-size local dimension as a tool for extracting geometrical properties of attractors of dynamical systems”

Martin Bonte June 19, 2025

The original goal of this study was to understand how the local dimension of the attractor of a dynamical system could be used to estimate the predictability of the future state of the system, and apply this in the case of radar images of rain. The local dimension using Extreme Value Theory (EVT) has been introduced and used in Faranda et al. (2017) to infer the current predictability of different ...[Read More]

How to include AI methods in your next proposal

Jan Dirk Wegner and Bettina Schaefli June 19, 2025

For all those of us who write research funding proposals, the massive avenue of powerful AI methods poses a serious challenge: how can we appropriately include such methods in our next research project? Is it mandatory, or can we happily focus on our field, lab or numerical methods that we used to always work with? For proposal evaluators, on the other hand, there is this feeling that many proposa ...[Read More]

What Distributed Acoustic Sensing (DAS) can find in the Atlantic Ocean

EGU Seismology ECS Team and David June 18, 2025

The contribution from David Schlaphorst, the member of ECS SM division team. David is a PostDoc in Dom Luiz Institute (IDL), University of Lisbon, where he does seismology research. Introduction Distributed Acoustic Sensing (DAS) has been used exponentially over the last decade.If you are eager to learn the basics but in song form try this link. In this blog post, we want to dive into one example ...[Read More]

What drives the extensional deformation in the central Apennines (Italy)?

Maaike Fonteijn and edited by Alexis Gauthier June 18, 2025

The central Mediterranean is a geodynamically complex region shaped by the interaction of multiple active subduction zones. In Italy, the central Apennines display a distinctive pattern of surface deformation that is proposed to be linked to a slab break-off beneath the area. In this week’s blog post, Maaike, a PhD student at ISTerre in Grenoble, France, explores the key processes driving surface ...[Read More]

Tracking the Footprints of a Vanishing Glaciers in the Greater Caucasus

Levan Tielidze June 13, 2025

Aerial image showing the climate change impact on small glaciers in the central Greater Caucasus, Georgia. Slopes are extensive deposits of moraines and loose rock debris, left behind by retreating glaciers. A small glacial lake (near the center-bottom of the image) fed by meltwater from the surrounding ice and snow was developed after glacier retreat [Credit: Levan Tielidze].

In this week’s blog, Levan Tielidze tells us about his recent glacier study from the Greater Caucasus. By combining geomorphology, remote sensing, and historical cartography, the team reconstructed nearly 200 years of glacier and climate change across one of the world’s most dynamic cryospheric frontiers. Glaciers’ transformation provides a high-resolution archive of post-Little Ice Age climate dy ...[Read More]

Highlighting: The Blatten landslide in Switzerland

Christophe Lambiel June 11, 2025

In the morning of May 28, 2025, the picturesque Swiss alpine village of Blatten sat quiet and serene in the Lötschen Valley. Exceptionally quiet, in fact, as the village was evacuated on May 19th after a local Natural Hazards expert spotted a worrisome change in a local mountain looming about the village, the Kleines Nesthorn: it was collapsing faster. The Kleines Nesthorn is a 3,341-meter peak w ...[Read More]

Monitoring the Ocean’s Green Pulse: A New Global Dataset for Phytoplankton Phenology

Sandy Thomalla June 10, 2025

Phytoplankton are tiny, single-celled organisms mainly found in the ocean’s sunlit surface, where they grow through photosynthesis, forming the marine food web’s base and regulating Earth’s climate by absorbing carbon dioxide. Their seasonal growth cycles—known as “blooms”—drive marine productivity and influence everything from carbon uptake to food security. But how can we track ...[Read More]
