These words are written on the SOOth anniversary of Columbus' discovery of the New World. Surely the deep-space exploration of other worlds in our Solar System over the past few decades is an event of similar magnitude. Man has traveled far enough to see Spaceship Earth suspended alone in black space. And he has voyaged even farther to marvel at the crescent Earth rising over the Moon's cratered terrain. Instrumented spacecraft have toured the entire Solar System even beyond the ninth planet Pluto. This work of science Morphology of the Rocky Members of the Solar System is an inquiry about our extended home. As with the Darwinian and Copernican paradigms, the nature of our planetary system, as the extended world around us, has great significance for those who ponder the human condition. The deep-space views of our Planet Ocean with its sweeping clouds, and moving oceans and creeping continents must rank as the greatest photograph ever taken. Viewing Spaceship Earth hanging in the vast void is an almost frightening experience. We are so alone! It is easy to understand why so many are attracted to a simpler account of origins, like the allegorical tale of creation written in heroic style (but eschewing math, maps, figures, tables, references, and evidence) in the first eleven chapters of Genesis. This treatise examines the morphology of the six rocky planets and their 27 satellites from a broad perspective.

The explosion of interest, effort, and information about the ocean since about 1950 has produced many thousand scientific articles and many hun dred books. In fact, the outpouring has been so large that authors have been unable to read much of what has been published, so they have tended to concentrate their own work within smaller and smaller subfields of oceanog raphy. Summaries of information published in books have taken two main paths. One is the grouping of separately authored chapters into symposia type books, with their inevitable overlaps and gaps between chapters. The other is production of lightly researched books containing drawings and tables from previous pUblications, with due credit given but showing assem bly-line writing with little penetration of the unknown. Only a few books have combined new and previous data and thoughts into new maps and syntheses that relate the contributions of observed biological, chemical, geological, and physical processes to solve broad problems associated with the shape, composition, and history of the oceans. Such a broad synthesis is the objective of this book, in which we tried to bring together many of the pieces of research that were deemed to be of manageable size by their originators. The composite may form a sort of plateau above which later studies can rise, possibly benefited by our assem bly of data in the form of new maps and figures.
