Growing geological Christmas trees: salt ‘Christmas-tree’ structures explained

Manel Ramos and Francina Saiz December 3, 2025

As geoscientists, we tend to see geology everywhere. Around Christmas, many people stare at decorated fir trees and twinkling lights; salt tectonicists stare at seismic lines and outcrops and see… trees as well. Tall stems, branching limbs, stacked “tiers” of material; a whole forest of geological Christmas trees hiding in the subsurface. In salt provinces around the world, from the Flinders Range ...[Read More]

SEDIMENTARY BASINS OF ALGERIA: THEIR ROLE IN EUROPE’S ENERGY SECURITY AND EMERGING GREEN HYDROGEN FUTURE

Ramon Lopez December 2, 2025

Algeria is often described as one of the great energy engines of Africa and the Mediterranean, and with good reason. Its proven oil and gas reserves are impressive, but what truly sets the country apart is the extraordinary complexity of its geological history. Over more than two billion years, tectonics, climate shifts and sedimentation created a series of basins that today host some of North Afr ...[Read More]

GMPV ECS Campfires – Mineralogy Meets Soil Science: Remediation, Weathering Processes and Interactions

GMPV ECS Campfires Team December 2, 2025

How do minerals shape the future of soils, and how do soils drive mineral transformations? This campfire highlights remediation strategies, contamination hazards, and mineral–soil interactions that control water quality, carbon storage, and ecosystem health. Join us on Wednesday, December 17th @ 11 am CET to explore how weathering, organo-mineral processes, and innovative approaches help tackle po ...[Read More]

ECS Spotlight: Evolution of the Dynamics of Centennial Hot Summers in Western Europe With Climate Change

Robin Noyelle December 1, 2025

Extreme meteorological and climatological events can be immensely damaging and disruptive to society. Understanding the physical mechanisms driving these events, and how they will evolve with climate change is crucial for informing societal adaptation to our changing climate. However, extreme events are, by definition, rare. Our capacity to understand these events is, therefore, hindered by the sm ...[Read More]

Climate change mitigation and India’s road to net zero

Pallavi Saxena, Saurabh Sonwani and Nicola Krake November 28, 2025

Climate change poses a significant threat to humanity, prompting numerous countries, including India, to implement effective mitigation strategies to alleviate its impact. India is recognized as one of the 17 megadiverse countries, harboring approximately 10% of the world’s known floral and faunal species. This rich biodiversity is largely attributed to its geographical diversity, encompassi ...[Read More]

A model to trace methane from the seafloor to the atmosphere

Knut Ola Dølven November 28, 2025

When people picture gas leaking from the seafloor, they often imagine plumes of bubbles that make up a direct path from the seabed to the sky. The reality, however, is far more complex and far more interesting. Between the seafloor and the atmosphere lies an entire ocean of physics, chemistry, and biology that controls the fate of the released gas. In fact, typically, most methane is dissolved int ...[Read More]
