🆕 Today we are proud to launch the Knowledge Hub — a digital space to learn, share, and celebrate the vital role the deep ocean plays in life on Earth.
The deep sea is vital, mysterious, & vulnerable. The more we know, the better we can protect.

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.
