Reef Fish of Navassa Island 2004
This record refers to reef fish data collected on the 2004 cruise to Navassa Island National Wildlife Refuge. The random point count method (Bohnsack-Bannerot 1986) was used and parameters collected include 1) sample information (latitude-longitude, depth, date, observer, time, visibility); fish species (numbers and size ranges); and 3) habitat information (percent benthic cover, bottom type, and rugosity).

Coral Reef Status of Navassa Island 2004
공공데이터포털
Benthic and habitat data collected on the 2004 cruise to Navassa Islands National Wildlife Refuge. Parameters include benthic cover, coral disease prevalence, location of fishing gear, coral density and sizes. Data were collected in situ by divers, some using digital cameras. Fishing gear locations were determined visually from boat transects.

CRED Rapid Ecological Assessment Reef Fish Survey at Tinian, Marianas in 2011
공공데이터포털
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.
