abstract
"In our final episode ... we discover that the ocean is sending us clear signals. Off the rugged and beautiful coast of British Columbia we meet scientists and fishermen who are shocked at the recent arrival of a voracious new creature ? the Humboldt squid. This monster-sized squid native to the equatorial waters of Mexico has moved north and ushered in a cascade of changes to the ecosystem. Their arrival is part of a disturbing pattern that is emerging with species movement being tracked around the world ... we illustrate how the ocean's chemistry and systems are being compromised by increased acidity, less oxygen and warming temperatures ... In the idyllic waters of the Bay of Naples, we get a glimpse of our future ocean, thanks to the mythic Mount Vesuvius. As scientists swim through lush green seagrass beds, they collect creatures whose shells are dissolving, and we discover that this amazing place has a terrible secret. It has been naturally acidified for millennia ? could this be our ocean's future?"-- One Ocean series website.
"With ... never-before-seen HD footage, this four-part documentary series from The Nature of Things dives into the world's vast interconnected ocean ecosystem - telling the story from its turbulent birth to its threatened future."--Container.
