Belt transects along 2 consecutively-placed, 25m transect lines were
surveyed as part of Rapid Ecological Assessments conducted at 3 sites at
Gardner Pinnacles in the Northwestern Hawaiian Islands in September, 2004
from the NOAA vessel Hi'ialakai (HII04-01). Raw survey data included
species presence and relative abundance, colony counts and size classes,
and visual estimation of percent cover. Either 0.5m or 1m on each side of
the transect lines were included in the belt (for a total of 50m2 or 100m2
per site), depending on colony density.
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 20 meters.

Observations were made by a single diver who is an expert in coral biology.
The population parameter survey is conducted one time per site per survey
year; it is not replicated.
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

As diver swam along the transect line, she inspected the corals whose
center fell within a 1m- or 2m-wide belt (i.e., 0.5 or 1m on each side of
the transect line, depending on colony density). Each such coral was
tallied by genus (and in most cases species )and classified by its maximum
diameter in one of 7 size classes: 0-5cm, 5-10cm, 10-20cm, 20-40cm,
40-80cm, 80-160cm, or >160cm. At the end of this survey, a visual
estimation of coral percent cover was made and recorded. Lastly, a larger
area around the transect belt was inspected for additional coral taxa that
did not occur within the belt; the relative abundance of all corals was
qualitatively assessed using the DACOR system (D = Dominant, A = Abundant,
C = Common, O = Occasional, R = Rare.
