National Coral Reef Monitoring Program: Stratified Random Surveys (StRS) of Reef Fish, including Benthic Estimate Data of the Mariana Archipelago since 2014

Metadata Updated: February 27, 2019

The stationary point count (SPC) method is used to conduct reef fish surveys in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The SPC method 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. Visual estimates of benthic cover and topographic complexity are also recorded, with benthic organisms grouped into broad functional categories (e.g., 'Hard Coral', 'Macroalgae'). A stratified random sampling (StRS) design is employed to survey the coral reef ecosystems throughout the U.S.-Pacific regions. For all regions, the survey domain encompasses the majority of the mapped area of reef and hard bottom habitats and the stratification includes island, reef zone, and depth, with the exception of the Main Hawaiian Islands that includes habitat structure type as well. Sampling effort is allocated based on strata area.

Data provided in this data set were collected as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led NCRMP mission around the Marianas Islands since 2014. Additionally, data collected as part of a shore-based survey effort around Guam in 2014 are included as these data are funded separately from but are complementary to the NCRMP-funded data.

Reef fish and benthic estimate data collected during SPC surveys can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.
