Benthic Habitats of American Samoa Derived from IKONOS Imagery, 2001-2003

This project is a cooperative effort among the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment; the University of Hawaii; BAE Systems Spectral Solutions; and Analytical Laboratories of Hawaii, LLC. The goal of the work was to map the coral reef habitats of American Samoa, Guam and the Common Wealth of the Northern Mariana Islands by visual interpretation and manual delineation of IKONOS satellite imagery. A two tiered habitat classification system was tested and implemented in this work. It integrates geomorphologic reef structure and biological cover into a single scheme and subsets each into detail. It also includes thirteen zones. Benthic features were mapped that covered an area of 71.5 square kilometers of which 10.56 were unconsolidated sediment and 60.94 were coral reef and hard bottom. Of the coral reef and hard bottom class, 62.8% is colonized by greater than 10% coral cover.
