Blue Planet Live

In the final programme of this week-long ocean health check, we look to the future to find out what it could hold for the next generation of marine life and how we can help.

The team looks at how scientists across the world are embracing technology to find solutions to the pressures faced by wildlife at sea.

In Mexico, Chris is at the end point of his journey, the southernmost tip of the Baja peninsula, to uncover the secret success of humpback whales. He joins a team deploying an innovative listening-in device that can unveil some extraordinary whale behaviour. Steve finds himself surrounded by stingrays as a team attempts to ultrasound some pregnant females to discover how successful the next generation will be.

As night turns to day, we join Liz live in Australia as she tunes in to an underwater dawn chorus and is captivated by fluorescent corals that light up the reef. She also witnesses tiny turtle hatchlings run the gauntlet of predators ahead of their epic migration.

Out on the open ocean in the Pacific, our expedition vessel reports back with exciting, never-before-seen discoveries that the latest technology has brought us from the deep, and we look to the future as the latest images arrive from submarine Alvin, revealing more about the hidden life in the seas that surround us.
