Pacific Reef Assessment and Monitoring Program: Stratified random surveys (StRS) of reef fish at coral reef sites across the Northwestern Hawaiian Islands from 2007-09-21 to 2012-08-19, including benthic estimate data from 2011 to 2012. (NCEI Accession 0178974)

Reef fish data provided in this data set were collected during stationary point count (SPC) surveys as part of Papahānaumokuākea Marine National Monument funded research cruises to the Northwestern Hawaiian Islands in 2007, 2009, 2011, and 2012. Benthic estimate data were collected at the end of the reef fish surveys starting in 2011.

The SPC 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. The data described herein collected by the Papahānaumokuākea Marine National Monument are complementary to the Pacific RAMP data collected by PIFSC Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division).

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. At each REA survey site, 1 or 2 SPC 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. Visual estimates of benthic cover and topographic structural complexity were also recorded at the end of the fish surveys, with benthic organisms grouped into broad functional categories (e.g., 'Hard Coral', 'Macroalgae').

In the Northwestern Hawaiian Islands, a stratified random sampling (StRS) design was employed to survey the coral reef ecosystems. 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. Sampling effort was allocated based on strata area and variability.
