More Than a Rain Gauge: When Salt Starts Steering the Sea

More Than a Rain Gauge: When Salt Starts Steering the Sea

Posted in: Ocean Sciences | Reviews & Perspectives | Ocean Science Jubilee Special Issue We usually think of ocean salinity as the ocean’s rain gauge. Rain, rivers, and melting ice freshen the surface; evaporation leaves it saltier. Seen from space, these changing patterns reveal how Earth’s water cycle is evolving, with wet regions generally becoming fresher and dry regions saltier as the cli ...[Read More]

Reflecting on fifty years of Mars through Viking 1’s lens

Reflecting on fifty years of Mars through Viking 1’s lens

On July 20, 1976, a machine of steel and titanium dropped through a thin atmosphere and touched the dirt of Chryse Planitia. Scientists at NASA held their breath, since five years earlier, the Soviet Union’s Mars 3 probe had died less than two minutes after touchdown. To mitigate this nightmare, engineers programmed Viking 1 to scan its own footpad first. If the lander sank into oblivion, hu ...[Read More]

Behind the Poster: An Interview with EGU 2025 Outstanding Student Paper Presentation (OSPP) Award Winner Carlos Castillo-Rivera

Congratulations on receiving the OSPP Award 2025! What was your reaction when you found out you had been selected for the award? I was very surprised when I received the email, and I read it several times to make sure it was real. After that, I felt extremely proud of my work because I could see the evaluation scores, comments, and recommendations from the judges. Their feedback confirmed that my ...[Read More]

The pulsed rise of the Nahuelbuta Range: How glaciers indirectly built a mountain in Patagonia

The pulsed rise of the Nahuelbuta Range: How glaciers indirectly built a mountain in Patagonia

Forearc ranges are a striking example of how tectonic processes shape our planet. The Nahuelbuta Range in southern Chile is one of such settings. This week, Ambrosio Vega-Ruiz from the GFZ Helmholtz Centre for Geosciences, Germany, is telling us the story of this remarkable range, exploring how climate feedback can influence tectonic uplift across coastal forearcs. Tectonic uplift before tectonic ...[Read More]

Chasing glacial lakes in the shadow of Everest

Chasing glacial lakes in the shadow of Everest

Turquoise lakes. Towering Himalayan peaks. A maze of rock, ice and meltwater. At first glance, this hardly looks like a glacier at all (Figure 1)… Yet as glaciers thin and retreat across the Himalayas, networks of meltwater ponds and glacial lakes are forming both on glacier surfaces and at their margins: one of the most visible signs of a changing high-mountain landscape. I spent four weeks in Ne ...[Read More]

Could the Chilean Altiplano host natural hydrogen for the energy transition?

Could the Chilean Altiplano host natural hydrogen for the energy transition?

The contribution from Sergio León-Ríos, Associate Researcher at the Advanced Mining Technology Center (AMTC) at the University of Chile, where he does seismology research. Post edited by Adam Ciesielski prior to publication. Introduction Hydrogen sits at the heart of today’s energy transition. From policy documents to industry roadmaps, it is widely promoted as a clean alternative to fossil fuels. ...[Read More]

Mangroves at the edge: Coastal ecosystems in a year of climate extremes

This Sunday, July 26, marks the International Day for the Conservation of the Mangrove Ecosystem. We are currently experiecing critical crossroads globally, where groundbreaking data on global forest recovery collides with the immediate threats of an escalating climate crisis.El Niño is pushing Pacific sea surface temperatures toward levels that rank among the highest on record, and climate specia ...[Read More]

What machine learning can and cannot tell us about floods

Collage based on a picture by Imad Clicks via Pexel

Floods are shaped by complex and nonlinear interactions between weather patterns, rainfall, soil properties, topography, land cover, and how wet a catchment already is. This complexity is one reason machine learning (ML) is increasingly used in hydrology. ML models can learn patterns from large and complex datasets with many variables.  Early in my PhD, while exploring machine learning models for ...[Read More]
