Essaouira, Morocco — here we go again 🌊🇲🇦
After heavy rain, clay-rich, iron-bearing soils from inland wash into the sea, turning coastal waters red.
Land and ocean, tightly linked.

2026 make it or break it!
Exciting science ahead!

​More than just a shell!
​Our new research shows these #mussel #holobionts are actually net #CO₂ sinks. A game-changer for how we view species interactions in the coastal systems!

📣 New paper!
#Intertidal mussels with cyanobacterial symbionts can act as net #CO₂ sinks.
Species interactions shape coastal #carboncycle!

Great energy yesterday at the Marine Station of @univlille.bsky.social!
We were thrilled to welcome the Parlement des Jeunes pour l’Eau, in partnership with the Agence de l’Eau, for a hands-on look at how we study and monitor plastic pollution. 🌊🔬

Wrapping up a great week of intertidal fieldwork — boots full of seawater, hands full of samples, and loggers full of data! 🌊🦪📊

Excited to share my feature in @nature.com Where I Work series, on my research into microplastics and their effects on marine biodiversity ☣️🧬

Thanks to Josie Glausiusz for the great conversation, and to Gianmarco di Costanzo for capturing my work on the cold shores of Iceland 🌊🦀📸

#Microplastics

📢Exciting news! BioNept PhD student Lorenzo Cozzolino (@univlille.bsky.social–LOG) is featured in Nature! 🌊
The interview highlights coastal fieldwork and the research we carry out on how microplastics impact marine #biodiversity🦀🦪🦭🦞🪼

So long, Cornwall… until next tide! 🌊
Still home to some of the most beautiful rocky shores.

Hidden reef discovered off UK coast stuns Attenborough film crew Discovered by chance during a David Attenborough documentary, a vibrant coral reef off Plymouth’s coast is now at the heart of a race to protect one of the UK’s rarest marine habitats

Great to see @bd-stew.bsky.social at @thembauk.bsky.social with film makers & PicSea map an IUCN Red List Vulnerable species, Eunicella verrucosa, in SW England.

Hi! Just a short survey in Cornwall this time, looking at mussels and their endolithic symbionts — for the rest, I trust the mighty @marclim-uk.bsky.social survey😎
No Wales stop this round, sadly😔but would love to visit Swansea and the Gower shores another time. Thanks so much for the kind invite!

Sometimes the smallest details steal the show 🦦🔍🐚

Heading from #France to #England for another intertidal survey in #Cornwall 🇫🇷➡️🇬🇧
On the ferry now—Cap Gris-Nez and Cap Blanc-Nez in the rearview, rocky shores ahead! 🌊🪸🐚

Beautiful, this truly looks like it belongs on canvas. It should be a painting! #art #intertidal

Sure, will do — and I’ve got a few other locations along the Moroccan coast too! 🇲🇦
@katynicastro.bsky.social @bionept.bsky.social

So long from the Moroccan intertidal 🇲🇦 — heading back to France 🇫🇷
Last snapshot: three tide pools side by side — perfect little replicates.

Sidi Kaouki — indeed stunning. It also reminded me of South Africa. Planning to come back in winter if anyone wants more official data beyond just photos.

Definitely harvested for food.
P. rustica I think 😊

Limpets on sale! Spotted at the fish market in Essaouira alongside the usual catch 🐚🦑🐟🦀🐙🦪
