Deep ocean mysteries and wonders

In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean -- from the deepest trenches to the remains of Titanic -- marine biologist David Gallo explores the wonder and beauty of marine life.

Most of Earth's surface lies hidden beneath water, with an average ocean depth equal to fifteen stacked skyscrapers. While humans have explored just five percent of the ocean, even this tiny glimpse has revealed volcanic eruptions, rivers, and astonishing life forms thriving where sunlight never reaches. The deep sea is home to ecosystems richer in diversity than any tropical rainforest. Our understanding of the planet remains incomplete until we venture further into these mysterious depths.
