"Narrator: This is the sea, as old as the world itself. It extends over three quarters of the surface of the globe. The sea: the birthplace of life, the great storehouse of minerals, the prison of haunting mysteries."

"Dr. J.R. Matheny: No frontier was ever explored by just one expedition."

"The Captain: I don't know about you guys, but I'm ready for a two inch steak!"

"See women trapped in fantastic caverns at the center of Earth!"
