Twelve quadrats were sampled along 2 consecutively-placed, 25m transect lines as part of Rapid Ecological Assessments conducted at 3 sites at Gardner Pinnacles in the Northwestern Hawaiian Islands in July 2003 from the NOAA vessel Oscar Elton Sette (OES03-06). Raw survey data included genus presence and relative abundance, and voucher specimens. Detailed taxonomic analyses of voucher specimens are presented.
