Title:
CRED REA Fish Team Belt Transect Surveys at French frigate Shoals,
2002
Belt transects along 3 consecutively-placed, 25m transect lines were
surveyed as part of Rapid Ecological Assessments conducted at 12 sites at
French Frigate Shoals in September and October, 2002 NOAA vessel Townsend
Cromwell (TC02-07). Raw survey data included species level abundance estimates.
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:
The maximum observation depth was 20 meters.
Fish observed:

Observations at each site were made by two divers both of whom are experts
in fish taxonomy. Observations were periodically checked during the
expedition for consistency between divers, and little discrepancy was ever
noted between divers. It should be noted, however, that this data set is
quite large, and probably includes typographical or other errors that might
be discovered at a future date.
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. Periodic
examination of the data through the duration of the trip showed no signs of
diver bias or other discrepancies.
Completeness_Report:
The survey sites were selected to be representative of the coral reef
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.
Data were collected by two divers swimming in tandem along the length of a
25m transect line. The team swam each transect two times. During the
initial swim-out, each diver recorded the abundance and size of all fish
observed over 20cm TL within 4m of their side of the transect line. On the
return swim, each diver recorded the abundance and size of all fish less
than 20cm TL within 2m of their side of the transect line. Fish were
identified to the lowest possible taxon which in most cases was the species
level. This data is recorded in the spreadsheet as DataTyp = QUAN.
Following the completion of three transect replicates at each site, the
divers spent their remaining bottom time roving the general area near the
site recording the presence of all fish species observed at the site. This
data is recorded in the spreadsheet as DataTyp = PRES. Upon returning to
the ship and Honolulu offices, data were error checked, and data from the
three fish surveyors were consolidated into one spreadsheet. Data have not
been modified, and this data set includes raw data.
