Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

The world's largest uninhabited island, Cocos, located 300 miles west of Costa Rica, is remote and wild, accessible only by boat and has no hotels or accommodation - it is for the determined diver. This guide provides details of a dozen open-ocean dives, whose attractions include sharks.

The book provides a pre-settlement historical account of the Cocos (Keeling) Islands and Christmas Island in their Indian Ocean context. The project began as a search for clues to locations of two 18th century Dutch shipwrecks, and was expanded into a general account of the early island histories and associated mythological Indian Ocean islands and creatures.
