The six Allen Coral Atlas Global Benthic Habitat Map classes described below were developed by Roelfsema et al 2013* with input from other coral reef benthic classifications.
The twelve Global Geomorphic Zones mapped by the Allen Coral Atlas are listed below, in logical order from external seaward-facing through to internal coral reef structural features. These zones are known to be fairly consistent across different biogeographic regions, and often associated with regionally distinct ecological assemblages of benthic animals and plants. Moreover, geomorphic classes like these have been shown to be reliable predictors of biological habitat richness and diversity.
