New video: A glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated. Watch this video to understand what happened. Study by @ciresnews #Antarctica #glaciermelt

Torres del Paine is another geological wonder of this region! Although the weather was a bit harsh, I was just amazed to see the granitic laccolith with my own eyes. Kudos: herds of guanacos and a puma

Following #ISAES2025 I have embarked from Puerto Natales to discover the Serrano and Balmaceda glaciers with a fantastic group of Antarctic geologists. The glacial landscape and the geology in the Magallanes region of Chile 🇨🇱 are breathtaking 🤩🏔️🧊❄️

Yesterday I was among the lucky few who enjoyed a guided tour of the new Chilean ice breaker “Almirante Viel” and the onboard scientific facilities #ISAES2025 in Punta Arenas 🇨🇱

Short paper in @joss-openjournals.bsky.social on 'segmenteverygrain', a machine learning model for segmenting grains in images. Review process: a bit slow, but transparent, friendly, rigorous, and useful joss.theoj.org/papers/10.21...

Measuring rock slides is cool, but modelling rock slides is cool too. So why not do both? Come join us at the beautiful Côte d'Azur! We have a fully-funded PhD opportunity available in the framework of the ERC UNREST project. Application window is open until 25 August: emploi.cnrs.fr/Offres/Docto...

New study in #Nature reveals the 'Gollum effect': nearly half of surveyed scientists report territorial behaviors—data hoarding, gatekeeping—mostly during #PhD. Early-career researchers bear the brunt; 1 in 5 left academia as a result.

Science’s ‘Gollum effect’: PhDs bear brunt of territorial behaviour
Survey respondents at all career stages report colleagues engaging in territorial and possessive behaviours — but early-career researchers are most often affected.

**BIG NEWS in the geology world!** For the first time, scientists spotted an active eruption along the mid-ocean ridge!!
They visited the hydrothermal vent the day before, where a vibrant ecosystem thrived in the sweltering water. The next day, everything was gone. ⚒️🧪

Volcanic Eruption in Deep Ocean Ridge Is Witnessed by Scientists for First Time (Gift Article)
Researchers diving in a submersible in the eastern Pacific realized that the landscape they had studied the day before had been glassed over by fresh lava.

Who wants to see waterfalls inside an ancient lava lake? Well… who doesn’t?
This is the Ray-Pic waterfall in Ardèche (SE France). Beautiful columnar jointing in a Pleistocene basanite full of mantle xenoliths 🤩⚒️

How beautiful is Tassie?! 🇦🇺
Back from Antarctica I took a couple days off to explore parts of southern Tasmania with some mates (in Mount Field NP & Maria Island NP). The luxurious forests with fern trees and waterfalls felt like a trip to Carboniferous times.
