Earth's last frontier is the great world beneath the sea. The oceans occupy fourteen times as much space as all the land above sea level. "In many respects," writes the author of this book, "the exploration of the undersea world is as important as probing outer space."

All About Undersea Exploration describes the scientific research of seagoing oceanographers. The book tells of bold exploration by helmet and Scuba divers, by bathyscaphe and submarine. It discusses the important discoveries made by undersea archaeologists, photographers, oil geologists, and cable experts.

Skillfully and dramatically, Ruth Brindze shows how far man has succeeded in solving the mysteries of the ocean -- and suggests the exciting discoveries to come.
