- Abstract:
-
To support a long-term NOAA Coral Reef Conservation Program
(CRCP) for sustainable management and conservation of coral reef
ecosystems, from 20110407 to 20110509, reef fish assessment
surveys were conducted, as a part of Rapid Ecological
Assessments (REA), during the Pacific Reef Assessment and
Monitoring Program (RAMP) Cruise HA1101 in the Marianas region
by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific
Islands Fisheries Science Center (PIFSC). During the cruise, 19
REA sites were surveyed at Tinian in the Marianas region. At
each REA site, fish biologists entered the water and conducted a
fine-scale (~700 m^2) and high degree of taxonomic resolution
REA survey to assess and monitor species diversity, size
distribution, and abundance of fish in shallow-water hard-bottom
(less than 30 m) habitats. Reef fish assessment surveys were
focused on cataloging the diversity (species richness),
abundance (numeric density) and biomass (fish mass per unit
area) of diurnally active reef fish assemblages. The stationary
point count (SPC) method was used to quantify reef fish species.
Two divers lay out a 30 m transect line, and position themselves
at the 7.5 and 22.5 meter marks. The SPC biologist then records
estimated size and abundance of all fish within a visually
estimated 15-m diameter cylinder centered on the stationary
diver (7.5-m radius, total area ~ 177m^2 per cylinder). The
diver first spends 5 minutes identifying all fish species in the
cylindrical area, then proceeds to count and estimate size
(total length) for each in a series of "instantaneous" point
counts or sweeps of the cylinder. Fish were identified at the
species level, wherever possible. All reef-associated fish,
including those in the water column, were surveyed. The survey
time for each stationary point count survey was approximately 20
min and generally two stationary point count surveys (one per
diver) were conducted at each fish REA site. After completing
REA surveys, divers noted the presence, at the survey site, of
any unusual fish species not counted during SPC counts, in order
to facilitate species lists per location.

Observations at each site were made by divers who have been
trained, and met minimum standards in identifying species
present at the survey locations and in estimating size of fishes
in survey counts. However, all species identifications are made
visually, sometimes in situations where a fish is only briefly
seen. Observations, including species identification and sizing,
were periodically checked during the expedition for consistency
between divers, and little discrepancy was noted between divers.
Data is checked after each cruise, but given the size of the
data set, there remains some possibility of typographical or
other errors.
- 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 clear indication of diver bias or other discrepancies.
- Completeness_Report:
-
The survey sites were randomly selected using a systematic process
based on available habitat and bathymetric habitats. However,
although efforts are made to include broad spatial coverage,
weather conditions and other environmental constraints may have
prevented the team from surveying exposed reef areas.

- Process_Description:
-
REA surveys are investigations that provide a high degree of
taxonomic resolution for reef fish communities. The surveys
were conducted by teams of two fish divers following a random
stratified design. Sites were randomly chosen within three
depth strata for hard-bottom or unknown reef areas. These
areas included forereef slopes of individual islands at depths
up to 30 meters, lagoonal-type patch reefs and offshore
oceanic banks. Transect placement was guided by: (1) a focus
on hard-bottom communities; (2) deploying lines along an
isobath to the extent possible at each site, and (3) laying
the transect lines into the prevailing current, if any.
