Twelve quadrats were sampled along 2 consecutively-placed, 25m transect lines as part of Rapid Ecological
Assessments conducted at 12 sites at Johnston Atoll in January, 2004 from the NOAA vessel Oscar Elton Sette
(OES04-01). Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed
taxonomic analyses of voucher specimens are presented.
Part of an initial assessment program in which corals, algae, fish, and other macroinvertebrates are co-sampled along
the same set of transect lines
Maximum depth was 18 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.
