Description:

Abstract:

Twelve quadrats were sampled along 2 consecutively-placed, 25m transect lines as part of Rapid Ecological Assessments conducted at 6 sites at Agrihan in the Commonwealth of the Northern Mariana Islands in August and September, 2003 from the NOAA vessel Oscar Elton Sette (OES03-07). 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.

Process_Description:

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.
