Pacific Reef Assessment and Monitoring Program: Stratified Random Surveys (StRS) of Reef Fish, including Benthic Estimate Data at Coral Reef Sites across the Pacific Ocean from 2007 to 2012

The stationary point count (nSPC) method was used to conduct reef fish surveys in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of NOAA's Pacific Reef Assessment and Monitoring Program (Pacific RAMP) from 2008 to 2012. Stationary point count is a non-invasive underwater survey method that catalogs the diversity (species richness), abundance (numeric density), and biomass (fish mass per unit area) of diurnally active reef fish assemblages in shallow-water (less than 30 m) hard-bottom habitats. Starting in 2010, visual estimates of benthic cover and topographic structural complexity were also recorded, with benthic organisms grouped into broad functional categories (e.g., 'Hard Coral', 'Macroalgae'). A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems throughout the U.S.-Pacific regions. For all regions, the survey domain encompassed the majority of the mapped area of reef and hard bottom habitats and the stratification included island, reef zone, and depth, with the exception of the Main Hawaiian Islands that included habitat structure type as well. Sampling effort was allocated based on strata area and variability.

At each REA survey site, 1 or 2 nSPC fish surveys were conducted, with each survey being carried out by a pair of divers each recording the number, size and species of all fishes within adjacent 15-m diameter cylinders. Benthic estimates were recorded at the end of the fish surveys.

Reef fish and benthic estimate data provided in this data set were collected during stationary point count surveys as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) led Pacific RAMP cruises. Data collected as part of Papahānaumokuākea Marine National Monument funded research cruises in the Northwestern Hawaiian Islands in 2007, 2009, 2011, and 2012 are also included as these data were funded separately from but are complementary to the Pacific RAMP data collected by ESD.
