Greenland sharks grow less than 1cm per year, reach sexual maturity at 150 years old and are the slowest sharks in the world. These deep-sea creatures live to at least 250 years, making them the longest-lived vertebrates on Earth. #DeepSeaWonders

The #HighSeasTreaty is now in force; implementation is the real test. Higher standards, precaution, and real protection mean no green light for deep-sea mining or destructive bottom fishing. As the COP process begins, the deep must be at its center. #DefendTheDeep

Today, the historic #HighSeasTreaty enters into force. The majority of the high seas is deep sea. As the COP process begins, the deep and the threats it faces must be at the center of implementation. #BBNJ #DefendTheDeep

🇧🇪 Belgium wants to host the #BBNJ, while supporting deep-sea mining🤯 What a contradiction. 44 NGOs to Belgium: back a precautionary pause. After all, deep-sea mining is the BBNJ treaty's first test 17 EU states have already acted. Belgium, it's your turn seas-at-risk.org/publications...

The deep ocean is not a resource frontier, it is a life-source. In our latest Knowledge Hub Q&A, PhD researcher Vilimae Kasanawaqa explains why #DeepSeaMining threatens food security, culture, sovereignty, and human security across the Pacific. Read more: https://bit.ly/4jI1QDe

In the Northern Mariana Islands, hundreds of residents express concerns regarding proposed deep-sea mining activities, highlighting community impact.

Cook Islands govt rejects research saying deep sea mining not profitable

Named after the mountain monster thanks to their ‘furry’ claws, Yeti crabs live along hydrothermal vents over 2,000 meters below the ocean surface. They host bacterial colonies on their arms, which they eat using mouth appendages. #DeepSeaWonders

Petition against deep sea mining near Mariana Trench gaining support

From the first sighting of a colossal squid in the wild to a seriously goofy octopus, 2025 delivered some astounding photos from the ocean’s depths

Scientists discovered a rare deep-sea habitat where hydrothermal vents and cold seeps occur together at Conical Seamount, Papua New Guinea. The unique conditions support highly specialized life – another reminder of how much of the deep ocean remains unknown. Read the study: https://bit.ly/4jpbnPy

Marine snow turns the deep sea into an unexpected winter wonderland. It’s made up of phytoplankton and biological debris that fall from higher in the water column and is a primary food source for many deep-sea creatures. #DeepSeaWonders

From the depths, hope rises. As 2025 comes to a close, momentum to protect the deep sea is growing - powered by science, solidarity, and global action. We’re carrying that energy into 2026. 🌊 #DefendTheDeep

Mesopelagic fishes, found in the deep sea, produce and excrete intestinal carbonate at rates expected from size and temperature, confirming their role as major carbonate sources at depth, with implications for the global #CarbonCycle. https://www.sciencedaily.com/releases/2025/07/250726234426.htm

Recent research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones, further endangering species already at risk of extinction. Read more in Science Daily: https://ow.ly/CtSN50XG94U

Seamounts are the ocean’s hidden rest stops — vital places where migratory species pause, feed, and survive on journeys across the planet. Protecting them means protecting ocean connectivity itself. One ocean. Many connections. #DefendtheDeep

🌊 #Norway hits pause on #DeepSeaMining till 2029 and gets a UN thumbs-up. 👍 🌍✋ Special rapporteurs write in a statement that this is a win for the ocean, human rights and future generations. 💪🐙 Thanks to @astridpuentes.bsky.social et al. #KeepItInTheSeabed #DefendTheDeep #Moratorium

The International Tribunal for the Law of the Sea’s 2024 #ClimateChange opinion classifies #GHGEmissions as marine pollution and imposes due diligence. This has implications for #DeepSeaMining, pressing the ISA and sponsoring states to adopt precaution, equity and climate-risk measures.

U.S. regulators have signaled interest in leasing seabed minerals near the Northern Mariana Islands, opening the door to deep-sea mining. Critics say the move was rushed & opaque, with little consultation, & warn it could cause irreversible marine harm & echo colonial exploitation in the Pacific.

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.

A five-year-long investigation into how deep-sea mining impacts biodiversity has finally been published.

📣 BREAKING: Deep-Sea Mining Watch is LIVE. Developed by the @ucsbenioffocean.bsky.social and powered by @globalfishingwatch.org technology, this new public data portal maps vessel activity linked to deep-sea mineral exploration around the world. Explore the new portal → bit.ly/4pg00v3

Seamount ecosystems can’t wait. We’re continuing to echo calls for the EU to advance deep-sea closures based on ICES science. Protection now = biodiversity for centuries. Protect seamounts. Lead by example. 🌊 #DeepSea #Seamounts #EUOceans #Conservation

Phys Org - Study measuring impacts of deep-sea mining machine finds abundance of animals at the site decreased by 37% The reduction in abundance of animals caused a 32% reduction in species richness in the directly impacted regions. phys.org/news/2025-12...

"Climate action begins in the deep. We cannot stabilise the climate without a healthy deep ocean. It has absorbed 90% of the excess heat and stored over 30% of the CO2 generated by humanity since the Industrial Revolution." https://bit.ly/4iuYZNj @deepseaconserve.bsky.social

Deep sea miners thought it would be easy to start mining the Arctic seafloor… 🤨 But thanks to campaigning, Norway has just halted all deep sea mining development! Wherever this industry tries to start, it fails. We can protect the oceans from extraction 💪 www.greenpeace.org/internationa...

I talked last week with @andrewlewin.bsky.social about How Deep Sea Mining Could Break the Ocean’s Most Important Wildlife Highways - www.youtube.com/watch?v=GlKV...

A new op-ed in @oceanographicmag.bsky.social by DSCC Executive Director Sian Owen highlights a critical gap in the outcomes of COP30: the deep sea. 🔽 #COP30 #DefendTheDeep #DeepSea

Seamounts are underwater oases where whales, sharks, rays and turtles feed, breed, and navigate, but destructive fishing is destroying these fragile ecosystems. In March 2026, countries will consider a landmark resolution at #CMSCOP15 to protect these critical habitats for migratory species.

Chimaeras (or ghost sharks) are found at depths of up to 2,600 meters below the surface, where they hunt prey with dot-like sensory organs on their face. Their closest relatives are sharks, but they’re also related to skates and rays. #DeepSeaWonders

There are widespread concerns that deep-sea mining for metals will damage fragile ecosystems. But if mining ever goes ahead, hydrogen plasma could shrink the carbon footprint of smelting the metal ores

New research led by @seaprinceaaron.bsky.social shows that 30 species of sharks, rays, and chimaeras are found in areas proposed for deep-sea mining, and nearly two-thirds are already threatened with extinction. https://doi.org/10.1016/j.cub.2025.09.019 #deepseascience #deepsea

Last week @sciaena-ngo.bsky.social passed on the torch to @peweurope.bsky.social to guard the deep sea criter! The tiny octupus will come back to #NEAFC in 2026 where it hopes to see progress being made towards EBFM and real deep sea protection 🐙 #MakeEBFMWork #VMEs #Seamounts #OceanLifelines

#COP30 helped to bring the ocean into the climate spotlight, but the #DeepSea is still at risk. We call on governments to support a moratorium on deep-sea mining and end destructive bottom trawling on seamounts. deep-sea-conservation.org/cop30-saw-th... #COP30 #DefendTheDeep

We’ve released Shifting Tides, a new briefing paper unpacking what sits behind TMC’s sudden pivot to the U.S. It’s a move being sold as progress but our analysis shows it introduces a tangle of political, legal, and reputational risks that can’t be ignored.

So… the new report on #DeepSeaMining outside American #Samoa basically says the quiet part out loud: the tech doesn’t work, the economics don’t work, and the strategy is 🤷. Turns out the real abyss isn’t the ocean floor, it’s the business model. Time to #KeepItInTheSeabed and #DefendTheDeep.

#NEAFC missed an opportunity to protect deep-sea ecosystems at its annual meeting last week. With #COP30 underway and the 2026 UN bottom fisheries review approaching, NEAFC must align with global biodiversity & climate goals. deep-sea-conservation.org/neafc-reject...

Don't use #ClimateAction or #RenewableEnergy as the excuse to damage the #Oceans!!! #COP30 #ClimateCrisis #Biodiversity We don’t need #deep-sea #mining, or its #environmental harms. Here’s why theconversation.com/we-dont-need...

The deep ocean is an enormous, natural carbon sink, storing massive amounts of carbon that would otherwise be in the atmosphere. Yet it can only continue to perform this critical role if it is healthy. As #COP30 wakes into Ocean Day, we shout loud and clear: climate action starts with the deep.

Trump sets sights on Pacific seafloor near the Marianas Trench. Efforts to expand deep-sea mining are alarming scientists and Indigenous leaders, who worry mining risks fisheries and food security. grist.org/global-indig... #Mining #Fish #Food #Ocean
