Twelve quadrats were sampled along 2 consecutively-placed, 25m transect lines, as part of Rapid Ecological Assessments, conducted at 10 sites at Guam in the Marianas Archipelago from 12 - 22 May 2007, aboard the NOAA ship Hi'ialakai, during the Reef Assessment and Monitoring Program (RAMP) Cruise HI0702. Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed taxonomic analyses of voucher specimens are presented.
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.
Maximum depth was 19 meters.

Algal genera were identified in the field by trained phycologists.
The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientist.
The survey sites were selected to be representative of the dominant habitats at this reef system.

A modified version of the Preskitt method was used to collect qualitative and quantitative algal data (Preskitt et al. 2004, Pacific Science). 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.
While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by errors or omissions in the data, nor as a result of the failure of the data to function on a particular system.
