We were grateful to attend a session at #VOCALIS2026 exploring the role #Europe can play in plugging in-situ monitoring gaps in the #Arctic, strengthening ocean monitoring, and improving current and future #Copernicus missions.

Thank you to the co-moderators, panellists and attendees.

Last month, @mercatorocean.bsky.social ran a training session on the #CopernicusMarine Service for Türkiye’s MaRDA project.

Led by Dr Muriel Lux, the session explored how Copernicus Marine's services could support Turkiye in boosting its #Ocean monitoring potential. https://bit.ly/4zavU0A

The #OSR10 reveals European seas under growing pressure.

As waters warm, #MarineHeatwaves intensify, and #Storms can grow more severe, threatening marine life and coastal communities.

Find out more in the #CopernicusMarine report:

A colorful infographic titled "Extreme Events in European Seas" shows various events in 2023-2024, using icons and arrows. In February 2024, storms in two Spanish ports cause high waves. Early spring 2024 sees a chlorophyll surge in the Northern Adriatic Sea, plus marine heatwaves in the Mediterranean and Black Seas, leading to record temperatures. Storms from 2023 to 2024 cause salinity drops in the Northern Adriatic Sea. In November 2024, a storm drops the Bothnian Bay to a record-low sea level.

📢 Marking 10 years of the #CopernicusMarine #OSR

A decade of #Ocean data on warming, rising sea levels, shrinking ice and acidification, alongside policy milestones and fish stock recovery.

Explore the decade:
🔗 https://marine.copernicus.eu/access-data/ocean-state-report/ocean-state-report-10

An infographic titled "10 Years of Ocean Change" highlights key statistics: Marine heatwaves have doubled in intensity, covering five times more area in the Mediterranean compared to 1996-2005. Sea levels have risen over 3 cm, and Antarctic sea ice declined sharply this decade. Logos of the European Union, Copernicus Marine Service, and Mercator Ocean International are displayed.

The image is an infographic about ocean acidification and anchovy stock recovery. It features text highlighting accelerated ocean acidification, global and European initiatives turning data into action, and the rebound of anchovy stocks after a 5-year fishing ban. Logos for the European Union, Copernicus Marine Service, and Mercator Ocean International are displayed at the bottom. Hashtags #OceanStateReport, #OSR10, and #CopernicusMarine are included.
