Favourable winds for the #BlueEconomy: investment is gaining momentum, dedicated funds are on the rise, and more investors are turning their attention to ocean-related opportunities. Despite this progress, the blue economy remains underfunded. #SDG14 Read the full report @ec.europa.eu#BlueEconomy⬇️

The Southern Ocean plays a central role in regulating the climate. Antarctic meltwater can strongly influence how the ocean absorbs heat and carbon, with clear implications for future #ClimateChange. @mpic.de#ClimateChange https://www.pnas.org/doi/10.1073/pnas.2502076123

Just in San Francisco Bay, 40% of deaths for gray whales were caused by blunt force trauma from ship strikes. This species is at risk of a population collapse. More via @oceanographicmag.bsky.social https://bit.ly/4w7DqZv #EndangeredSpeciesDay @marinemammalcare.bsky.social @calacademy.bsky.social

The Arctic is experiencing more and more extreme weather events. The rise in heatwaves, droughts and winter warming marks a new climate era with serious risks for Arctic ecosystems. @ilmatieteenlaitos.fi https://www.science.org/doi/10.1126/sciadv.aee7980

Kelp forests and eelgrass meadows in Nova Scotia sequester far more carbon than previously thought, mainly through dissolved organic carbon (DOC) export. Ignoring these DOC pathways leads to major underestimates of the climate value of coastal vegetation.

What do the green crab 🦀, sea walnut 🌰 and zebra mussel 🦓 have in common? They are all invasive species! Marine invasive species can have a devastating impact on biodiversity, ecosystems, fisheries, human health, tourism and coastal development. Learn more in our Issue Brief.

#MarinePollution remains one of the biggest threats to our ocean. Ocean currents funnel large amounts of human-made lead from the Atlantic into the Arctic, where much of it remains trapped. @geomarkiel.bsky.social#MarinePollution https://scienmag.com/arctic-ocean-absorbs-human-made-lead-from-atlantic/

Ocean warming is reducing seabird survival across the North Atlantic, especially after breeding when birds gather in warming hotspots. Populations exposed in multiple seasons face the steepest declines. #WorldMigratoryBirdDay

The deep ocean makes up 90% of the Earth’s marine environment & is its largest biome, but remains mostly unexplored. More scientific discoveries are revealing how important the deep ocean is to our planet. DYK the deep sea plays a central role in regulating Earth’s temperature & currents? #DeepDay

Today we celebrate #DeepDay, an international day launched by our member @deepseaconserve.bsky.social#DeepDayto amplify support for the deep and celebrate this critical environment for all of humanity. Join the celebrations! 🥳

People visiting and living near Port-Cros National Park🇫🇷 care deeply about marine pollution but often lack a full understanding of ecosystem health. The study shows that stronger, place-based #OceanLiteracy efforts are needed to turn concern into informed action. https://bit.ly/4w0FZfR

#Microplastics may undermine the ocean’s ability to regulate climate by disrupting carbon cycling and releasing greenhouse gases. A review argues that #PlasticPollution and #ClimateChange must be tackled together, not as separate environmental problems.

[Commentary] Ahead of the Our Ocean Conference, Ghana is advancing its 30x30 goals by establishing its first marine reserve. By protecting ecologically significant waters, Ghana is protecting marine life while safeguarding the future of coastal towns. *The views expressed are those of the author.

Global talks on #PlasticPollution have stalled as countries disagree over responsibility & ambition. The authors of this study argue that a flexible, standards-based #GlobalPlasticsTreaty with shared monitoring and support could unlock progress & strengthen action against marine plastic pollution.

Marine pollutants build up through food webs and reach people through seafood, threatening biodiversity and human health. Climate change further amplifies these risks and calls for stronger monitoring, regulation and integrated action from ocean to table. #MarinePollution

Hands-on field activities boost #OceanLiteracy in students. Teachers piloting a pedagogical model saw strong value when embedding ocean citizenship across primary school curricula.

🌿 Restored salt marshes and mangroves can rebuild carbon and nitrogen stores, but full recovery takes decades. Plants recover faster than soils, and restoring existing wetlands is more effective than creating new ones. https://scienmag.com/reviving-coastal-wetlands-carbon-and-nitrogen-recovery/

Expanding #MPAs is not enough on its own. As countries work towards the #30x30 target, this study outlines 5️⃣ ways to make conservation more effective, from shared standards and climate-ready planning to better coordination and fairer outcomes for people who depend on the ocean.

The world has committed to reducing marine pollution by 2025, but currently: 🛢️+80% of global wastewater gets discharged back into the environment ☣️ 300-400 million tonnes of toxic chemicals are dumped every year 🥤12-14 million tonnes of plastic enter the ocean every year. Learn more:

Happy #WorldPenguinDay! 🐧 People believe penguins live in the North Pole, but DYK that 8 of the 17 species can be found in #Antarctica and the sub-Antarctic islands? What other fact(s) do you know about penguins? ⬇️ 📷 Julie Chandelier/Ocean Image Bank @antarcticasouth.bsky.social#WorldPenguinDay

Last year on #EarthDay, ‘Antarctica: The Melting Silence’ premiered. There is still time to enjoy the immersive experience that brings the icy wilderness of the Southern Ocean into the heart of the city. 🇦🇶 📍 Free + open to the public until May. @commsinc.bsky.social @greenpeaceuk.bsky.social#EarthDay

Across six European seas, managing #MPAs always involves trade-offs between conservation and economic use. This study concludes that no single solution fits all contexts but transparent, inclusive trade-off negotiation is essential for effective MPAs.

🌊 Ocean energy is a vast and promising source of renewable power—but it remains largely untapped. To address the triple planetary crisis, we must scale up blue investments and unlock the ocean’s full potential to secure a sustainable future. 🌎 #SDG14 #EarthDay 📷 Philip Thurston

Pure #OceanOptimism: 🇨🇱 granted full protection to 360,000km² of 🌊 around Juan Fernández & Nazca-Desventuradas marine parks, creating one of the world’s largest fully MPA & surpassing 50% ocean protection. #30x30 oceanographicmagazine.com/news/one-mil...

While the 10% of global ocean protected is a moment for celebration, it serves as a stark reminder of the work left to do: to triple in just 4 years to meet the #30x30 #KMGB Framework goals and effective management of #MPAs. @oceanographicmag.bsky.social#30x30

Protecting reef fish has helped prevent a tipping point on the Great Barrier Reef. However, climate-driven heatwaves increasingly limit how much extra benefit fish protection and culling can provide.

In Cape Town 🇿🇦, recreationists and tourists feel strongly connected to the ocean and recognise major threats, but only a few are involved in deeper stewardship activities or intend to do more. This study highlights the potential of ocean-based recreation to support #OceanLiteracy.

A recent study shows that even at 2°C warming, climate impacts can be as severe as those expected at higher temperatures (3/4°C warming), highlighting the need to consider worst-case scenarios in climate planning. #ClimateChange https://phys.org/news/2026-03-extreme-global-climate-outcomes-2c.html

On #WorldHealthDay, we are reminded that our health and survival depend on our ocean's health. #OceanClimateAction is needed to protect, manage and restore the ocean to conserve our ocean for us and future generations. Together, we must #ListenToTheOcean. 🎥 @IocUnesco

🌊 10% of the global ocean is now officially recognised as protected! A big step forward - but celebration must be tempered with urgency, because we only have four years to triple that number if we're to successfully meet the 30x30 goal. Full speed ahead! oceanographicmagazine.com/news/10-of-t...

Coastal protection is expanding, but most marine restoration remains far behind target. This paper outlines 5️⃣ linked solutions for scaling action, including better MPA design, policy reform, and restoration that addresses root stressors, including @ocean-climate.bsky.social Ocean Breakthroughs.

A “reef recovery” media frame about a 2022 coral report triggered global misinterpretation and fuelled climate-sceptic narratives. Nearly half of coverage misrepresented climate risks, and over 40% of Twitter discussion became denial-aligned. #ScienceComms #OceanComms
