Featured Video


A feature-length movie exploring the peculiar life that thrives at sites of chemosynthesis in the deep sea, from the towering chimneys of hydrothermal vents to the surreal landscapes of cold seeps, and the sites of partial chemosynthesis that form at whale-falls and sunken wood.

The deep ocean is a place of wonder, and challenges for life. With minimal resources, no sunlight, and only a slow trickle of nutrients making its way down here as 'marine snow', life must find unique ways to exist in the depths. Food is scarce, and with very little energy, survival in the depths is a challenge for any creature. There are some locations in the deep that life has clung to for millions of years, and where food and energy is ever abundant.

Coming Soon

2. Night on the Reef

Episode 2 turns everything on its head to explore the peculiar alien-like world of suspension feeders that emerge after dark to feed on the vertically migrating plankton.

4. A Troubled Paradise

Featuring interviews with cameraman Edi, who has spent 30 years diving in the region, we will discuss the anthropogenic impacts affecting the Coral Triangle.

1. The Coral Triangle

Episode 1 will serve as an overview of the reef ecosystem, and its incredible colourful inhabitants.

Watch the trailer for the upcoming five-part feature-length series about the Worlds of the Deep Sea, created in collaboration with Schmidt Ocean Institute and featuring stunning 4K visuals from their ROV SuBastian.

2. The Midnight Zone

Below a depth of 1,000 metres, the light of the sun is altogether absent, and a host of dramatic animals take to the stage.

4. Seamounts and Canyons

Breaking up the uniformity of the abyssal plain, the seamounts and canyons provide solid ground where colourful corals and gardens of sponge create complex reefs.

1. The Twilight Zone

Just below 100 metres, the ocean midwater becomes a world of gloom, where dazzling bioluminescent drifters and fish of bright silver shimmer in the twilight expanse.

3. The Abyssal Plain

Beneath the crushing pressure of kilometres of water lies a great sea of silt and clay, where curious mud-dwellers abound.

5. Hydrothermal Vents

Where tectonic plates move apart, towering cities can be found in the depths; vents of superheated water, hosting incredible life.
