🆕 Today we are proud to launch the Knowledge Hub — a digital space to learn, share, and celebrate the vital role of the deep ocean for the Earth.
The deep sea is vital, mysterious, & vulnerable. Understanding it is key to protecting it.

New financial analysis highlights growing risks around The Metals Company’s #DeepSeaMining plans.
With no proven revenue or track record, deep-sea mining remains a speculative and risky bet.

Deep sea mining companies are desperate to exploit minerals at the bottom of the Pacific ocean. To get their way, they’re making false claims about the economic and environmental benefits this destructive industry will bring.

❌Deep Sea Mining tests impact over a third of seabed animals.
Machines mining minerals in the deep ocean have been found to cause significant damage to life on the seabed, scientists carrying out the largest study of its kind say.

A new op-ed in @Oceano_mag by DSCC Executive Director @siankowen highlights a critical gap in the outcomes of COP30: the deep sea.
#COP30 #DefendTheDeep #DeepSea
COP30 elevated the ocean, bringing it closer to the heart of the global climate agenda, but the deep sea – everything below 200 metres and making up roughly 90% of the ocean – stayed buried in the margins. oceanographicmagazine.com/fe…

The deep ocean is still mostly unexplored—and so are the risks of mining it. Without sufficient scientific knowledge, it's impossible to write rules that truly protect marine life.
If we can't measure the impact, we shouldn't take the risk. @deepseaconserve
ALT No pause? No protection. Deep-sea mining would cause irrevocable damage to our fragile deep-ocean ecosystems.

We were at the @UN_FAO_GFCM annual meeting urging stronger deep-sea protection in the Mediterranean. Pilot projects show the costs for fishers are minimal, yet countries missed a key chance to act.
The EU must lead & extend the trawl ban to at least 800m by 2026. #DefendTheDeep
