Red Sea

The team explores the remote and unexplored Southern Red Sea, teeming with marine life and home to some of the warmest waters on the planet.

With unique access, expedition leader Paul Rose, environmentalist Philippe Cousteau Jr, maritime archaeologist Dr Lucy Blue and marine biologist and oceanographer Tooni Mahto investigate whether the vibrant coral here can help other coral reefs threatened by global warming.

They dive in one of only two places on Earth you can see a new ocean being born; they explore the wreck of an Italian ship, to find her top secret, deadly cargo; and they uncover archaeological evidence of one of early man's first encounters with the sea.

And Philippe Cousteau Jr has an emotional journey to the remains of an ambitious underwater village established by his grandfather, Jacques Cousteau, in 1963 to discover whether humans could live beneath the waves.
