In the depths of the ocean, a new contest between the US and China emerges Around the Cook Islands, the world’s two most powerful countries are exploring the possibility of deep-sea mining for critical minerals

The U.S. and China are racing to the bottom - literally. 🌊 #CookIslands caught in the middle, with #DeepSeaMining impacts risking marine ecosystems. This a test of whether we’ve learned anything from history. @theguardian.com covers this well today. Let's #DefendTheDeep.

The #ArcticCircleAssembly Ocean plenary sent a clear message on #DeepSeaMining 🌊: We know too little about the #DeepSea and once the damage is done, it may be irreversible. ❌ Let’s choose wisdom over haste and apply a #moratorium. 💙🪸 That is the only way to #DefendTheDeep.

The #Arctic is warming fast and so is the geopolitics. 🧊⚠️
As nations eye new shipping routes and #DeepSea resources, fragile marine ecosystems risk becoming collateral damage. Happy to be in #Reykjavik with colleagues to raise awareness of ocean action at the #ArcticCircleAssembly.

Policy brief: Why Arctic states must protect the deep - Seas At Risk Interest in the Arctic’s natural resources is growing, including its deep-sea mineral resources. Two Arctic countries are moving ahead with plans for deep-sea mining, Norway and the U.S., despite moun...

An unproven industry is eyeing the Arctic: #DeepSeaMining. 🌊⚒️ Fortunately, global momentum for a halt is growing. 🪸 As the Arctic Circle Assembly begins, see this new policy brief which explains why Arctic states should #DefendTheDeep. @seasatrisk.bsky.social 💡

Bare 2 av 10 vil åpne for gruver på havbunnen Flertallet er klart imot gruvedrift på havbunnen, viser en undersøkelse. Blant Aps egne velgere er det enda mindre populært.

Out today: 🧐 Only 20% of Norwegians want #DeepSeaMining. Quite a few more want to "fjord-get it"!
Time for the upcoming government to stop digging where there’s no public support - and let the #DeepSea rest. 🌊

Sharks, rays, chimaeras further threatened by deep-sea mining | University of Hawaiʻi System News The habitat of 30 species of sharks, rays, and chimaeras, also called ghost sharks, overlap with areas where proposed deep-sea mining may occur.

We’ve mapped the surface of the moon better than the #DeepSea - yet some still want to mine it before meeting the neighbors (sharks, rays, ghost sharks!). Maybe curiosity, not greed, should guide our next dive. 🌊✨ #ProtectTheDeep #NoDeepSeaMining #Moratorium #KeepItInTheSeabed

Hard-Fought Treaty to Protect Ocean Life Clears a Final Hurdle

🌊 The #BBNJ Treaty hits 60+ ratifications & will enter into force next year. This is great proof that multilateralism can work! 🎉

Now, if the world can unite to protect the #HighSeas, it can also unite to stop #DeepSeaMining. More work ahead!

The Missing Piece: Minerals Processing and Deep Sea Mining The resilience and diversification of mineral supply chains have become significant topics of concern in recent times.

🧭 Let’s be real: #DeepSeaMining won’t magically unchain us from China’s grip.

Without processing capacity, we’re just shipping rocks while Beijing keeps the refinery keys. 🔑🌊

American Samoa says no to deep-sea mining. The Trump administration might do it anyway. The CEO of a seabed mining startup says the decision about mining leases will be made in Washington, D.C.

#DeepSeaMining without Free Prior and Informed Consent, an internationally recognised principle?

That’s not “innovation” that’s #Colonisation 2.0.

#AmericanSamoa has already said NO. Respect it. 🌊✊

Cook Islands confronts critical questions on identity as debate on deep sea mining grows The question facing its people is no longer just about mining - but about identity, sovereignty, stewardship, and the ocean that binds them all.

Mining the #DeepSea isn’t just a tech gamble, it’s a cultural wound. #CookIslands debate shows why the Pacific needs a #Moratorium on #DeepSeaMining: protect identity, sovereignty and the ocean that sustains us. This in a fresh piece by @rnzrss.bsky.social today. #DefendTheDeep #KeepItInTheSeabed

🚨 New article out in #Nature: The #InternationalSeabedAuthority is nowhere ready to monitor #DeepSeaMining. 🌊⚒️

We are delighted to welcome Croatia as the 38th country supporting a moratorium or precautionary pause on deep-sea mining!

The wave continues to grow, with more countries saying no to #DeepSeaMining

#StopTheMachines

Glad to see #Croatia joining the growing group of countries calling for a #PrecationaryPause on #DeepSeaMining here at the #InternationalSeabedAuthority. With 38 countries now supporting this position, the momentum is building to protect the planet’s least understood and most fragile ecosystem.

Millions of Mysterious Deep-Sea Nodules Offer Clues to Life—And Riches to be Mined When researchers discovered evidence of “dark oxygen” last year, the news spread around the world, but the biggest challenge to the science comes from its funders

One year after the discovery of #DarkOxygen, @sciam.bsky.social explores what happened thereafter.
Still mind-blowing. Still a reason to pause #DeepSeaMining.
We should know more before we destroy what we don’t understand. #KeepItInTheSeabed #ISA #StopDeepSeaMining

Panama’s Juan Carlos Monge 🔥 at the #ISA Assembly on #TheMetalsCompany and their plans for #DeepSeaMining:

“This immoral feeding frenzy of modern-day commercial pirates… is a recipe for disaster.”

The #DeepSea isn’t a prize for the richest or the fastest. It’s the #CommonHeritageOfHumankind.

#Palau President Whipps just shredded #TheMetalsCompany at the #ISA Assembly:

I’m in Kingston for the #ISAAssembly. Governments must step up and protect the ocean before it’s too late.

'Significant declines' in some species after deep-sea mining: research Deep-sea mining could impact marine life stretching from the tiniest bottom dwellers to apex predators like swordfish and sharks, a major piece of industry-funded research found Thursday.

#DeepSeaMining companies: “The ocean will recover!” 🌊✨

Science: “Cool, we checked but the #DeepSeabed would not like it.” 🫠

Massive species decline, barely any recovery. #StopDeepSeaMining #PrecautionaryPause #DefendTheDeep #KeepItInTheSeabed

The Ocean Still Holds Mysteries. That's Why We Must Save It The more we explore and protect the ocean, the more we benefit, whether in the form of economic returns or scientific breakthroughs.

The #ocean is still mostly unexplored, and yet it sustains life, feeds millions, and holds answers to our future. 🌊

Interesting piece by @wendyschmidt.bsky.social and @donabertarelli.bsky.social in @time.com about why we need to protect it. Now’s the time to invest in discovery, not destruction.
