Man's understanding of how this planet is put together and how it evolved has changed radically during the last 30 years. This great revolution in geology - now usually subsumed under the concept of Plate Tectonics - brought the realization that convection within the Earth is responsible for the origin of today's ocean basins and conti nents, and that the grand features of the Earth's surface are the product of ongoing large-scale horizontal motions. Some of these notions were put forward earlier in this century (by A. Wegener, in 1912, and by A. Holmes, in 1929), but most of the new ideas were an outgrowth of the study of the ocean floor after World War II. In its impact on the earth sciences, the plate tectonics revolution is comparable to the upheaval wrought by the ideas of Charles Darwin (1809-1882), which started the intense discussion on the evolution of the biosphere that has recently heated up again. Darwin drew his inspiration from observations on island life made during the voyage of the Beagle (1831-1836), and his work gave strong impetus to the first global oceanographic expedition, the voyage of HMS Challenger (1872- 1876). Ever since, oceanographic research has been intimately associ ated with fundamental advances in the knowledge of Earth. This should come as no surprise. After all, our planet's surface is mostly ocean.

Incredibly rich and realistic illustrations take readers up close to the curious creatures and plants that thrive in the vast severe habitat of the ocean's floor. Marine biologist and renowned children's book writer Sneed B. Collard III introduces children to many fascinating sea creatures–from bioluminescent fish to giant tube worms–that survive without sunlight. A history of deep-sea exploration from sonar to submersibles shows how far scientists have come in their ability to investigate these great depths. Inspire young readers to explore the possibilities of marine science.

The author participated in 38 sea going expeditions including the first manned-submersible project to explore the Mid-Atlantic Ridge. This book provides a comprehensive overview of the past 45 years of sea floor exploration. It summarizes the mineralogical and petrological composition of sea floor rocks, ocean floor volcanism in relation to the geological setting and the discovery of hydrothermal activity. In addition to learning about various scientific missions and their objectives, the reader is introduced to rift zones where the sea floor is being created, as well as to fracture zones, intraplate volcanoes, and the structural setting of subduction zones
