Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Some suspect that these vents even hold the key to understanding the...

"It is said that the seafloor is a desert, a vast and uniform wasteland, all but devoid of life. Textbooks on the shelf in my laboratory say so. But I know that is not true", writes scientist and submersible pilot Cindy Lee Van Dover in the Introduction to Deep-Ocean Journeys. Van Dover has ventured miles below surface waves to the bottom of the sea, driven by her desire to understand the complex and thriving ecosystems recently discovered near volcanic vents. These ecosystems are models for sites where life might have originated on this planet and where extraterrestrial life is speculated to...
