"We want to attract responsible people who appreciate nature," told me Ramona Remmen, local museum manager on Norway's Træna archipelago. While tourism can support these tiny islands' economy, its uncontrolled growth risks disrupting both the community and local ecosystems.

Where marine science meets tourism: on Faial Island, the whale-watching company Naturalist stands out — it’s run entirely by scientists 🐋 Marine biologist Gisela Dionísio told me why that makes it a win-win.

Fish are vital for🇲🇷#Mauritania’s economy and food security. But some key species face serious threats. In Nouakchott, I spoke with Mohamed El-Hafedh Ould Ejiwen, head of IMROP, about how science is guiding efforts to preserve and restore fish stocks.

With floating turbines, offshore wind parks can move into deeper, windier waters — unlocking 80% of Europe’s sea area for green power. At @WindEuropeEvent, I spoke with Stine Myhre Selås from @Equinor about this next leap for renewables. #FloatingWind

Some sectors can’t go electric — but they can go green. In Esbjerg, I interviewed Lars Dyrholm from European Energy on how #GreenHydrogen and #EMethane, produced with offshore wind energy, can replace fossil fuels for hard-to-abate industries. #EnergyTransition

Les pêcheurs 🇫🇷 testent des balises #DolphinFree — une nouvelle approche pour éloigner les dauphins des filets. À Audierne, j’ai parlé avec Virginie Lagarde du #CDPMEM29 : cette balise peut-elle protéger les dauphins tout en aidant la pêche à reprendre normalement ?

French fishers are testing #DolphinFree pingers, using a new approach to keep dolphins away from nets. In Audierne, I spoke with #CDPMEM29 Virginie Lagarde about what fishers think of this tech — can it protect dolphins while helping fishing in the Bay of Biscay return to normal?

The 𝟳𝟬th episode of my TV series "Ocean" airs this week! This time, we explore how Northern Sweden managed to preserve its wild salmon while many other regions couldn’t.

Italy’s underwater WiFi. Portugal’s fish-powered farms. Europe’s #blueeconomy startups are innovating big—but funding them? In this Ocean episode, w/@euronewsgreen shows how the EU’s #BlueInvest is helping turn ocean ideas into real change. 🌊 https://t.co/x90OjSu1nX

Here’s me explaining the ⁦@WSENSE_IoUT⁩ underwater communication system while diving with Italian marine biologists in the latest episode of Ocean 🤿 Looks interesting? Watch the full episode on ⁦@euronews⁩ TV and online in seven languages 👉 https://t.co/A3kcKhLMep

GETTING AROUND THE WORKPLACE 🛗 Normal people: take elevator 🤿 Me: gets towed by speedboat in full SCUBA gear

Yesterday, we filmed a dive in the “Secche della Meloria” marine protected area near Livorno, where Italian researchers tested an underwater acoustic “WiFi/GPS” system developed by @WSENSE_IoUT through the WTAG project. Look out for my TV story on it, coming in November!

Five offshore wind test sites (including @plocan that I visited this year) teamed up to improve conditions for floating wind projects — they aim to tackle challenges like permitting to speed up testing and innovation, keeping EU at the forefront of floating wind technology

It takes a scientist a full day at the microscope to count plankton in a seawater sample, but AI can do the same work in just 30 minutes. Ocean data is exploding, opening up incredible possibilities. Don’t miss this month’s Ocean episode, which I produced in Italy and Belgium!

🌡️🌊 "Spreading like wildfires" We were pleased to welcome @euronews' Denis @Loctier to our office and share insights on the work of Mercator Ocean to monitor and forecast marine heatwaves. Watch the video report and learn more at this link ➡️ https://t.co/ZazvBwv185

Today is the day ❗ Tune in tonight on Euronews TV to watch the new episode of ‘Ocean’ documentary series and explore the innovative research #CMMI is conducting. ⏳ Tonight at 20:45 CET (21:45 Cyprus time) in 7 languages! 📍 #Euronews TV & https://t.co/JSlVIZIl17

Pierre Bahurel is the DG of @MercatorOcean — it develops software to model and forecast key ocean features using @CMEMS_EU data. Their weekly bulletin provides sea users with early warnings of marine heatwaves and supports policymaking. 📺ᴏᴄᴇᴀɴ by @euronews & @EU_MARE

Underwater sensors in #Cyprus constantly record sea temperatures, giving a clear picture of ongoing warming. 🌊🔥 @Louishadj, marine ecologist at @cmmicyprus, told me he expects many local corals to die this season based on the data. 📺ᴏᴄᴇᴀɴ by @euronews & @EU_MARE

In Larnaca, Nikhil Thomas from @cmmicyprus explained me how #photogrammetry helps create detailed 3D models of #coral reefs to monitor their health over time — a vital tech to understand the impact of marine heatwaves on fragile ecosystems. 📺ᴏᴄᴇᴀɴ by @euronews & @EU_MARE
