Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed taxonomic analyses of voucher specimens are presented. Purpose: Part of an initial assessment program in which corals, algae, fish, and other macroinvertebrates are co-sampled along the same set of transect lines. Supplemental_Information: Maximum depth was 15 meters.

Logical_Consistency_Report: The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientist. Completeness_Report: The survey sites were selected to be representative of the dominant habitats at this reef system.

One diver recorded the presence and relative abundance of algal genera inside each of the twelve 0.18 m2 quadrats and collected voucher specimens, while the second diver photographed each quadrat. An additional random swim was performed by the divers to collect qualitative samples.
