Megalodon had the teeth to make a meal of a whale. Fossils show that it did--but the menu was more varied than a succession of enormous animals. They ate their fill of what was swimming in the ocean around them. Small whales, other marine mamma...

While spooky season is officially in the rearview mirror, it's not too late to talk about ghosts, is it? Not the bedsheet-wearing, candy-hunting ones that may have haunted our doorsteps last week, but a much older, more elusive kind: the geochemica...

Saturn is best known for its spectacular rings, but the rings are closely connected to the surrounding Saturnian environment. One of the sources of material in this system is the small icy moon Enceladus. During the Cassini mission, spectacular plumes were discovered erupting from fractures near Enceladus' south pole, known as the tiger stripes. These plumes consist predominantly of water vapor, accounting for about 90% of the ejected mass, with the remaining ~10% in the form of icy dust grains. The plume material is continuously released into space, and because of Enceladus' low escape velocity, much of it escapes the moon and spreads throughout Saturn's magnetosphere.

We are excited to announce the 24th edition of Geodesy Campfire - Share Your Research in November. 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, Alexey Kupriyanov and Marcel Iten. Below, you can find the details of the topics awaiting us. We will have time to network after the presentations.

Permian Rotliegend sandstones form one of northwest Europe's most important gas reservoirs. Yet, despite decades of mature field production and apparently excellent reservoir properties, something has never quite added up. On paper, these reservoirs look excellent. Core measurements often show high permeability and good reservoir quality. Once taken into production, however, they can behave very...

By Natalie Raia, AGU Board of Directors The AGU Board of Directors is charged with the duties of care, loyalty, obedience, and foresight for the organization. It's not surprising, then, that the theme of resilience -- for AGU, for our scientific community, and for the knowledge infrastructure that supports science -- has been at the forefront of conversation lately. Nature provides us with...

For this month's episode of HydroTalks, we're thrilled to welcome Dr. Hossein Hashemi, an associate professor in the Division of Water Resources Engineering at Lund University in Sweden and a member of the Center for Advanced Middle Eastern Studies. His research focuses on groundwater and surface water management in arid and water-scarce regions, combining remote sensing, artificial intelligence and climate analysis.

The problems started in 2023 with Project Red in Nevada. Fervo's self-published paper described their small demonstration project as "commercial scale". But Project Red was neither commercial (as in economically profitable), nor of significant scale. While providing some interesting results that they could have quietly built on, instead Fervo's initial reporting for Project Red overstated...

Extreme heatwaves of unprecedented magnitude are expected to become increasingly frequent in coming decades. These heatwaves come with severe consequences for human health, infrastructure planning, and economic prospects - particularly during events lasting multiple weeks [10]. In recent decades, Western Europe has become a hot-spot for record-breaking and long-lasting heatwaves [9], raising a critical question: How extreme could future heatwaves in this region plausibly get?

Everyone wants something from Arrakis. The Emperor wants control, the great houses want spice, and the Fremen would quite reasonably like everyone else to leave. I would settle for a geological map. Preferably with a few cross-sections, although I realise that asking someone to carry a seismic survey across sandworm territory might complicate the risk assessment.
