Belt transects along 2 consecutively-placed, 25m transect lines were surveyed as part of Rapid Ecological
Assessments conducted at 10 sites at French Frigate Shoals in the NW Hawaiian Islands (NWHI) during 1 September - 4
October 2006 in the NOAA Hi'ialakai Reef Assessment and Monitoring Program (RAMP) Cruise (HI0611). Raw survey data
included species presence and relative abundance, colony counts and size classes by genus, and determination of
benthic cover using the line-intercept method. Depending on colony density, 0.5 or 1 m on each side of the transect
lines was included in the belt (for a total of 25-100m2 per site).
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 18 meters.

Observations were made by two divers who are experts in coral biology. The population
parameter survey is conducted one time per site per survey year; it is not replicated.
With the exception of the non-quantitative survey along the backreef, the same methods of
data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists.
The survey sites were selected to be representative of the dominant habitats at this reef system.
Efforts were made to include broad spatial coverage of the reef area, but weather conditions or other environmental
constraints may have precluded the team from surveying windward or exposed sites.

Instrument parameters
A diver swam along the length of three 25m transect lines that had previously been laid out along an isobath by a
fish survey team and haphazardly tossed a 0.5m x 0.5m quadrat 16 separate times. The diver identified all corals
whose center fell within the quadrat to the species level and listed coral species occurring within 0.5 m2 of each
side of the transect lines and the size class to which the maximum diameter of the colony belongs ( 5 cm; 5-10 cm;
10-20 cm; 20-40cm; 40-80 cm; 80-160 cm; or greater than 160 cm). For each coral colony, the maximum diameter and
diameter perpendicular to the maximum was measured using a hand-held tape measure.
A random swim is then conducted in the vicinity of the transect lines within an area of about 5,000m2 in which all
coral species are listed and assigned a DACOR abundance code based on visual estimation (D equals Dominant, A equals
Abundant, C equals Common, O equals Occasional, R equals Rare). If bottom time permits, corals showing signs of
disease, bleaching, or abnormal growth are tallied, described, and photographed.
