- Abstract:
-
Belt transects along 2 consecutively-placed, 25m transect lines were
surveyed as part of Rapid Ecological Assessments conducted at 8 sites at
Ofu and Olosega Islands in American Samoa in February, 2004 from the NOAA
vessel Oscar Elton Sette (OES04-02). Raw survey data included genus
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.
- Purpose:
-
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
- Supplemental_Information:
-
Maximum depth was 17 meters.

Observations were made by one or two divers both of whom are experts in
coral biology. The population parameter survey is conducted one time per
site per survey year; it is not replicated.
- Logical_Consistency_Report:
-
The same methods of data collection were used at each of the sites surveyed
at this location, and were conducted by the same scientists.
- Completeness_Report:

The survey sites were selected to be representative of the dominant
habitats at this reef system

As divers swam along the transect line, they 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 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.
