Majestic lenticular clouds over the Patagonian Andes (near Aguilera Glacier)

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. www.nature.com/articles/d41... 🧪

**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. ⚒️🧪 My latest for @nytimes.com

Tuesday could be Strontium Sulfate day! Why not… Clusters of pale blue celestite crystals from Madagascar ⚒️🧪

⚒️

To brighten your weekend: pink rhodonite crystals (manganese inosilicate) from Madagascar 🤩⚒️

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 🤩⚒️

Exploring Nice’s backcountry geology with 2nd year students - near Entreveaux ⛰️⚒️

Back from a week in the field with MSc students mapping and studying deformation in variscan rocks from the Maures-Tanneron Massif near St Tropez 😍

What’s not to love with boudins! ⚒️

Bedmap3 is now out rdcu.be/ecTmO

And of course Aussie wildlife was there 🐾

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.

Looking back to some fieldwork memories earlier this year…

Happy new year 2025 from Dumont D’Urville station in Adélie Land, East Antarctica… not the best weather for geology though

One of the many pros of the French Riviera are the landscape and geology diversity… and canoeing on the Mediterranean on a sunny winter morning with a view on the snowy Alps
