⚓️ Just back from a #research cruise with the RV Wim Wolff.

🌊 On the Western Scheldt #estuary, we did 13-hour measurements of #hydrodynamics & #sediment transport.

🎓 The cruise is funded by #Delta-ENIGMA large-scale research infrastructure: delta-enigma.nl.

Fascisme krijgt ruimte door een hardnekkige misvatting: dat jij het niet kunt stoppen. Dat klopt niet. Gezamenlijk kunnen we ons weren tegen de woede en het wantrouwen die onze democratie overspoelen, schrijft @rosansmits.bsky.social.

Dat komt neer op een simpele keuze – die keuze is aan jou.

The Dutch government is planning to make devastating budget cuts on higher #education and #science. 🧪 Reason for all Dutch universities to participate in a relay strike that passes from city to city. Tomorrow, it will be my university's turn. 🪧 @woinactie.bsky.social

🌱 Plants that establish on a #mudflat strongly increase the #complexity & drainage efficiency of #tidal channel #networks. 🌊 #Vegetation promotes channel incision & prevents topographic smoothing. 💻Our SFERE model (doi.org/10.5281/zeno...) illustrates this 👇For the study: doi.org/10.1038/s414... 🧪⚒️

How scientists can drive climate action: celebrate nature and promote hope
After years of storytelling and running classes and festivals, I’ve seen first-hand how a love of nature makes people want to protect it.

Just saw this very clear video by @hopeenpie.bsky.social on X. Such a clear and positive explanation of why we need to restore natural processes in our #rivers to prevent disastrous #floods 🌿🌊

📢 Good news! Our review paper, "Tipping points in river deltas", will be open-access available & downloadable as PDF for the coming 2 weeks!

👇 Please use that opportunity:
