The existing reef appears to be developed on an older surface that extends as a terrace into the lagoon and beyond the seaward margin of the reef. A sketch map shows the distribution of the terraces in relation to the existing reefs.Reef zonation is briefly described, and a classification of reef types based upon the characteristics of the marginal zone is presented. Illustrations are given from Bikini's reefs and those of near-by atolls. A sketch map shows the distribution of the reef types at Bikini relative to prevailing winds and currents. The processes of reef growth and unusual areas wherein the existing reef appears to be undergoing destruction are also described and figured. This content is PDF only.
