AMMONITES IN CONCRETION

Fossil Huntress | 28 July, 2026
At first glance they look like ordinary stones--rounded, weathered, unassuming. But then you notice the delicious hints: a spiral ghosting through the surface, a faint rib, a seam where time is ready to split wide open--it's magic!Ammonites, l...

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 Nepal's Sagarm?th? National Park in May and June 2025 as part of the Glacial Lake Observatory (GLO) project surveying these lakes and their downstream valleys using drones. The goal: to collect thousands of aerial images that can be transformed into detailed maps and 3D models, helping us better understand how these lakes are evolving and the flood hazards they may pose. What followed was more than 200 km+ in trekking, 12,000 m in elevation gain, thousands of drone photos, countless cups of Chiya (Nepali milk tea) and an unforgettable field season.

The increasing importance of DHI’s in the Rotliegend play of the Southern North Sea

GEOExPro | 28 July, 2026
It sounds odd, bearing in mind the quality of broadband seismic data available these days: unlocking an offshore gas province without using seismic DHI's to de-risk exploration drilling. Yet, that is what happened in the Southern North Sea, where the Upper Permian Rotliegend sandstones proved to be gas-bearing in many closures that were primarily drilled...

A gentle rebuke, well taken

Matt and I had a great time at DinoCon 2026 this weekend just gone. One of the highlights for me was running into Tim Versteeg and Joschua Knüppe, who run the PaleoStream channel. They had a stall in the vendor hall, stocked with some fantastic palaeoart.

Geology Word: Ooid

Ooids are sedimentary grains that form by precipitation of calcium carbonate around a nucleus. The nucleus may be an organic particle, or a mineral grain, or a shell fragment.Repeated precipitation results in a concentric coating around the nucleus. Depending upon the saturation state of the sea and other variables like temperature, ooids may be made up of either calcite or aragonite. Both have the same chemical formula, CaCO3, but they differ in their atomic structure.Ooids form in shallow seas where wave energy is vigorous. The turbulence results in the particles getting suspended and redeposited on the sea floor, resulting in an even coating around the nucleus. Beaches, tidal channels and regions near reefs are areas where ooids are accumulating today in tropical seas around the Bahamas, Caribbean, the Persian Gulf, and the Red Sea.The picture shows an ancient ooid. This particle is around 350 million years old from the Mississippian Period, deposited in a warm shallow sea which occupied the State of Alabama in North America. I collected the rock sample on a field trip during my PhD days.

EGU Campfire Geodesy – Share Your Research – 21st Edition

EGU Geodesy Division | 27 July, 2026
We are excited to announce the 21st edition of Geodesy Campfire - Share Your Research in August. 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, Shrishail Raut and Michal Cuadrat-Grzybowski. Below, you can find the details of the topics awaiting us. We will have time to network after the presentations.

The reservoir will always have its final say

GEOExPro | 27 July, 2026
With 500 Megawatts (MW) of plant capacity in construction for their flagship geothermal project at Cape Station, Utah, one might think that Fervo had already answered the questions on the subsurface reservoir and lower-than-advertised well productivity. Unfortunately, this does not seem to be the case. Confirming sufficient well productivity can only be known through well...
