All the facts about the world's oceans are here without any of the wondrous mysteries. This is a dry factual study beginning with a summer of how oceans came to be. It continues with such topics as continental shelves and how they function, the formation of islands, how and currents work, what living creatures can be found on the ocean from plants and plankton to mammals and the work of some important oceanographers. The manner of telling is hardly inspiring. The book is useful only for those readers who want straight fact, having been motivated by livelier accounts.
