Early this month, #CopernicusEU's #ImageOfTheDay shared two spectacular #Sentinel2 images of tidal dynamics at France's Passage du Gois: an island causeway completely flooded by the tide every day. Here's some quick outputs from our #DEAIntertidal coastal elevation workflow over the same area!

Volcanoes, Svalbard, and Greenland walk into a bar in the Early Triassic: doi.org/10.57035/jou... Publishing this article in @sedimentologika.bsky.social was the best author's experience so far! Diamond Open Access for the win!

We need to change how we publish science! New article with @camthomas.bsky.social : “Diamond is the new Green: why Green OA is not sustainable long-term.” About 15 min, perfect for a weekend reading with a coffee: @sedimentologika.bsky.social 💎 doi.org/10.57035/jou...

🚨 New Opinion Piece 🚨 Vaucher & Thomas discuss the sustainability and equity of different Open Access publishing paths and promote a shift towards Diamond OA. Read the full publication here: oap.unige.ch/journals/sdk... @romainvaucher.bsky.social, @camthomas.bsky.social

🔔 Introducing our new journal layout! We invite you to explore it in our website at sedimentologika.org 💻 #sedk #layout #openaccess #journal

🎉New paper with Brian Beaty: After the end-Permian ME, burrowers didn’t just return, they rewired seafloor chemistry. Shallow particle mixing revived C & S cycling (<200 kyr); full P recycling waited on deeper burrowers (>1 Myr). Congratulations Brian! paper: onlinelibrary.wiley.com/doi/10.1111/...

When you see the dramatic impact that a 1° change in the dip of the strata has on fluid flow in porous media, we field geologists might need to rethink our "+-5° is totally fine" when measuring strata dip angle. Thanks Thomas Poulet for the collaboration! doi.org/10.1130/G538...

🚨 New Paper 🚨 MacDonald et al. investigate passive CO2 mineralisation in anthropogenic carbonate deposits through isotopic geochemical analysis of different samples collected across Scotland and Northern England. Read the full publication here: oap.unige.ch/journals/sdk...

#AEGC2025 Perth Tomorrow we’re tackling self-organisation & allogenic artifacts in sedimentary basins — how to tell real vs apparent cycles, and what that means for basin reconstruction. I have gifs and memes, hope it helps 😇 ⏰ Tues. 11:20 📍 Sed & Strat session, riverside theatre.

So we can only hope of major volcanic eruptions to stay below+1.5 °C of global warming in the next five years? How do we react to that?

I might live under a rock. But #NotebookLM is f***ing incredible! Here is a little podcast on our #DOA paper on the coastal dynamics of the Gulf of Carpentaria we wrote with @satellitesci.bsky.social, Miquel Poyatos, Björn Nyberg, Rachel Nanson, Stephen Sagar, Leo Lymburner! tinyurl.com/3j9fb9sh

If you're like my office mate today and you need a break, check out our #preprint in Climate of the Past on the Phanerozoic climate record of #Svalbard. This manuscript is a beast that Aleks Smyrak-Sikora (NTNU, lead author) managed brilliantly! Well done! egusphere.copernicus.org/preprints/20...

Come and join our @sedimentologika.bsky.social team!🏜️🏞️🏝️

Hei #GeoSky, quick wording-question: Would you rather write 1. The Lower Triassic climate was.. or 2. The Early Triassic climate was..? Using the word stratum instead of climate, then I'd go option 1; with climate, I'm a little hesitating, though. P.s. "During the Early Triassic" isn't an option

The SedK team extends its best wishes for the New Year 2025 to the entire Sedimentology community! 🎆 💎Thank you to all our contributors, readers and supporters!
