Raw survey data included species presence and relative abundance, colony counts and size classes by genus, and determination of benthic cover using the line-intercept method. Depending on colony density, 1 m on each side of the transect lines was included in the belt (for a total of 25-50m2 per site). Purpose: Part of a long-term monitoring program at biennial intervals in which corals, algae, fish, and other macroinvertebrates are co-sampled along the same set of transect lines. Supplemental_Information: Maximum depth was 16 meters.

The population parameter survey is conducted one time per site per survey year; it is not replicated. Logical_Consistency_Report: With the exception of the non-quantitative survey along the backreef, the same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists. Completeness_Report: The survey sites were selected to be representative of the dominant habitats at this reef system. Efforts were made to include broad spatial coverage of the reef area, but weather conditions or other environmental constraints may have precluded the team from surveying windward or exposed sites.

The diver identified all corals whose center fell within .5m on either side of the transect to the species/genus level and estimated the sizeassigned each colony a size class based on estimates of the maximum diameter of the colony ( 5 cm; 5-10 cm; 10-20 cm; 20-40cm; 40-80 cm; 80-160 cm; or greater than 160 cm).
