🧊 The @EU_Commission has proposed a new #Arctic strategy focused on strengthening #resilience, advancing #ClimateResearch, supporting #EconomicSecurity and creating opportunities for #ArcticCommunities.
🔎 Read more about the EU’s priorities 👇eurocean.org/np4/2169.html
The Arctic is changing fast.
Europe’s new Arctic Strategy sets out 4 priorities:
🔹Climate action & research
🔹Security & resilience
🔹Sustainable economic growth
🔹People at the centre
Together we create a secure & prosperous Arctic future.

⚠️ How can we detect #earthquakes in the remote Central #Arctic?
A new study led by our #ECOPs presents an automated detection method that identifies #UnderwaterEarthquake signals.
🔎 How this improves #seismic monitoring in the Arctic? Read it here 👇 seismica.library.mcgill.ca/a…
🎧🌊 Listen! The #ArcticOcean is calling
A two-day public event in Bergen exploring the hidden world of #UnderwaterSound, through #science, #art and hands-on activities 🐋
📅 16-17 October
For all ages. Come have a listen👂

Hard to believe it’s almost a month since #CommOCEAN2026! 🌊
Since, the #FloatYourBoat floats have been released near the North Pole by #HiAOOS and are now drifting with the #Arctic ice. 🧊

⛵🧊 And they're off!
After travelling aboard KV Svalbard, the tiny wooden boats of #FloatYourBoat are now drifting with the #Arctic #sea #ice near the #NorthPole.
Where will the ice take them? Follow their adventure with #HiAOOS! 👇

🌊🧊 #HiAOOS is proud to be part of the #international #ocean observing community.
In the rapidly-changing #Arctic, #internationalcooperation is essential for long-term observations.

Our Ocean changes rapidly.
And it impacts our planet, our economies, and our communities.
Today, @MarkJCarney and I are rallying the world in support of ocean observation.
Which gives us eyes and ears beneath the waves ↓ xitter.cf/i/broadcasts/1qxvvepjZ…
🧊Two years beneath the #Arctic sea ice—and all five #HiAOOS #moorings are safely back!
They've collected a unique ocean dataset in one of Earth's least-observed regions.

#DYK that observations don’t have to stop when a #RV leaves the #Arctic?
#HiAOOS is testing tech that continues collecting data in remote ice-covered waters
Highly relevant to #OceanEye and #Polhavet2050, to better understand the changing ocean
