Robert Ballard: The astonishing hidden world of the deep ocean

The astonishing hidden world of the deep ocean

Exploring the deep sea reveals life where none should exist, from thermal vents at 650°F to alkaline environments with a pH of 11.

With only 0.1% of the ocean explored, discoveries like underwater brine pools and methane volcanoes hint at Earth's unseen marvels.

Ocean's depths hold human history too, with perfectly preserved shipwrecks like the Titanic offering glimpses into our past.
