Title:
CRED REA Fish Team Stationary Point Count Surveys at Uracas, 2003
Stationary Point Counts at 4 stations at each survey site were surveyed as
part of Rapid Ecological Assessments conducted at 4 sites at Uracas in the
Commonwealth of the Northern Mariana Islands (CNMI) in August, 2003 from
the NOAA vessel Oscar Elton Sette (OES03-07). 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:
Common Name Scientific Name
Species Genus Family Order Class Phylum- Kingdom
Division
Bony Fishes Osteichthyes Vertebrata Animalia

Observations at each site were made by a single diver who is an expert in
fish taxonomy. The team of three REA fish divers rotated roles with two
divers performing belt-transect surveys and one diver performing stationary
point counts at each survey site. 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 a single diver who remained motionless while slowly
turning in a circle for a duration of 5 minutes recording the abundance and
size of all fishes greater than 25cm TL observed within a 10m radius. At
each survey site, 4 replicate counts were conducted. 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 four SPC replicates at each site, the diver spent his
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.
