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 the Titanic -- marine biologist David Gallo explores the wonder and beauty of marine life.

David Gallo works to push the bounds of oceanic discovery.
Active in undersea exploration (sometimes in partnership with legendary Titanic-hunter Robert Ballard), he was one of the first oceanographers to use a combination of manned submersibles and robots to map the ocean world with unprecedented clarity and detail.
He was a co-expedition leader during an exploration of the RMS Titanic and the German battleship Bismarck, using Russian Mir subs.
On behalf of the Woods Hole labs, he appears around the country speaking on ocean and water issues, and leading tours of the deep-ocean submersible Alvin.
