Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed taxonomic analyses of voucher specimens are presented. 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.

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.
