Into the Abyss: Chemosynthetic Oases
Exploring hydrothermal vents, cold-seep habitats, and food-falls including whale-falls and the communities at shipwrecks

The Stages of Whale Decomposition
Fallen whale carcasses, abundant in the deep-sea, form ecosystems of their own. As it decomposes, different stages support a succession of marine biological communities. It is these complex and fascinating stages that are here explored.

Mysteries of the Twilight Zone | Worlds of the Deep
In the deep ocean, life is concentrated at chemosynthetic oases where primary production is made possible via chemosynthesis at cold seeps and deep sea hydrothermal vents. The non-chemosynthetic regions of the deep are divided into two very different worlds. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this movie, we delve into the Twilight Zone.
