🎨 On #DeepDay, we celebrated seamounts at the Lord Howe Rise and South Tasman Sea Symposium with an outstanding mural created by the Chilean artist #PayoSochting and Bla! Art Collective, illustrating their rich biodiversity and aboriginal knowledge and art. 🌊⛰️
#ProtectSeamounts
This week marked #DeepDay 2025. As deep sea mining negotiations progress, concerns grow over how to safeguard submerged tangible and intangible cultural heritage. This article sheds light 👇 #SundayRead
🐙 Did you know the deep sea is home to as many as 1 million species? We’re celebrating #DeepDay by working to protect these critical deep ocean habitats and the animals living there from deep-sea mining.
❌ We must stop deep-sea mining before we do irreversible harm to the ocean: bit.ly/3Za22C3
A photo from an undersea robot or ROV, the robotic arm is reaching out towards a small rock partially buried in the seafloor sediment, with a translucent white colonial tunicate growing on it.
A different rock, picked up from the seafloor and displayed with a ruler in front of it. It has sponges, anemones, and lots of other tiny invertebrate life growing all over it.
I heard it's #DeepDay, so here's a fun deep sea fact: we picked up 18 rocks from deep in the North Atlantic and looked at every single animal that was using those rocks. In total, we found ONE HUNDRED (and one) species* of invertebrates on those rocks alone 🧪

We loved having you! Great way to recognize #deepday
Very cool to see Aotearoa punching above its weight in this paper discussing how much of the deep seafloor we have seen.
Even more knowing that continuing this research is expensive & threatened by cuts to science by the current government. #DeepDay 🌊🌏🐙🦑

#DeepDay and #WormWednesday!
Happy #DeepDay. The deep sea seems so far away and yet we are more connected to it than we think.
I consider myself very lucky that my work allows me to go to and study this amazing ecosystem.

We know more about the moon than the deep sea — yet deep-sea mining threatens this fragile, vital world. On this #DeepDay, OceanCare calls for a global moratorium before it’s too late. Some places must remain untouched. 🪼

This #DeepDay, let’s celebrate science & Indigenous knowledge—and act on what that tells us.
The deep sea is under threat from destructive #DeepSeaMining. Let knowledge, not exploitation, shape our ocean’s future.

Science is only just beginning to explore the deep sea—but many Indigenous cultures have long held deep-rooted knowledge of these waters.
On #DeepDay, we spotlight the value of scientific and traditional wisdom for ocean protection. #DefendTheDeep
To mark #DeepDay, we hosted recently a screening of Deep Rising, a powerful documentary directed by Matthieu Rytz and executive produced by Dona Bertarelli, amongst others, followed by a team discussion on the future of the deep ocean.
A powerful reminder of why this mission matters.
Happy #DeepDay for those who celebrate. Take a few seconds and glide through marine snow in the aphotic zone. It consists of organic matter (yes also 🐟💩) and inorganic particles. It provides nutrients to the deep sea and is crucial for pumping CO₂ from the surface into the oceans‘ depths.

Fewer people have explored the deepest parts of the ocean than have walked on the moon! The deep sea remains one of Earth’s most remote frontiers, an uncharted
treasure trove waiting to be discovered. Dive into a world of discovery this #DeepDay. @deepseaconserve.bsky.social #DefendTheDeep🌊 #STEM
It’s #DeepDay !! Protect the deep sea-our planet’s largest, least explored habitat. #DefendTheDeep Get involved! deep-sea-conservation.org/explore/deep-day @deepseaconserve.bsky.social
Happy #DeepDay!
Today is all about celebrating the deep sea —our planet’s largest, least explored habitat—and advancing knowledge to protect it. Because the more we know, the better we can #DefendTheDeep: bit.ly/3RUrojw
On #DeepDay, we come together to spotlight the critical threats facing the deep ocean, from the looming risk of deep-sea mining to the destructive impacts of bottom trawling on vulnerable marine ecosystems.
We also celebrate the community working to protect this vast, mysterious world.
#DeepDay 2025 is all about advancing knowledge—scientific and cultural—to protect the deep sea. The more we know, the better we can protect.
There is so much to discover in the deep sea, but what we know is that it is critical for the functioning of our planet. buff.ly/dglpCPc
Scientists estimate that the top 1 meter of seabed contains 3117 gigatonnes of carbon.

We are the first to witness the wonders of the deep, and perhaps the last with the power to protect them.
On #DeepDay, I reaffirm a stance I've long held: the deep deserves caution, not haste.

🎉 On #DeepDay, we join @deepseaconserve.bsky.social in celebrating the critical role the deep ocean plays in making life on Earth possible.
The deep ocean is teeming with life, holds cultural histories, and is one of our greatest allies in the fight against the climate crisis. buff.ly/dglpCPc
🎉 Happy #DeepDay! Today, we join our partners at @deepseaconserve.bsky.social in celebrating the deep sea.
We’re proud to support the coalition as its communications partner, working to raise awareness, build momentum, and drive action to #DefendTheDeep.
