diving deep with sylvia

Diving in a 1 person submarine with Sylvia Earle.

This sub was one in a line of small deep diving vessels that eventually led to the development of the submarine that James Cameron used when he teamed with national Geographci on his historic dive to the deepest spot on the planet, the Marian Trench
