"Volcanoes of the Deep Sea" is a science adventure that will plunge audiences into the ocean 3,000 metres deep for an unprecedented experience of this vast and little-explored dimension of our planet.

The film follows a team of scientists as they dive to research mysterious hydrothermal vents on the mid-ocean ridge of Atlantic Ocean. Water and chemicals spewing from these hydrothermal vents can easily reach more than 400 degrees Celsius (hot enough to melt lead), and the pressure can reach a crushing 24,000 kPa.


Spewing out thick clouds of minerals and metals, this hydrothermal vent is swarmed with shrimp that feed on bacteria.


Discovered near a hydrothermal vent site in the Pacific Ocean, this little-known octopus is nicknamed "Dumbo" for its large ear-like fins.

More amazing yet, chemicals in the vent fluid, such as hydrogen sulfide, provide food for a microbial community that is the base of the food chain for vent life. The deep-sea hydrothermal vent environment is one place on Earth where life lives off the chemical energy of the planet itself rather than on the energy from the Sun.

"Volcanoes of the Deep Sea" reveals the planet's marine depths as never before, putting audiences into the most alien and hostile environments on Earth and into contact with the planet's strangest creatures and phenomena. The film will also explore the implications that deep ocean discoveries may have for our understanding of the emergence of life and our search for its traces elsewhere in the universe.

This hexagonal trace fossil Paleodictyon nodosum dated tens of millions of years ago may be created by a creature that is still alive in the deep Atlantic Ocean.


The submersible "Alvin" drops into the depths to shoot a towering structure at a recently discovered vent site in the Mid-Atlantic.
