| Title: | National Coral Reef Monitoring Program: Benthic Images Collected from Stratified Random Sites (StRS) across the Pacific Remote Island Areas from 2018-06-08 to 2018-08-11 (NCEI Accession 0187564) |
| Abstract: | The data described here are benthic habitat imagery (photographs) from benthic photo-quadrat surveys conducted along transects at stratified random sites by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD)--formerly the Coral Reef Ecosystem Division--as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The photo-quadrat surveys are part of Rapid Ecological Assessment (REA) surveys for corals and fish conducted from June 8 to August 11 during the ESD-led NCRMP mission to the Pacific Remote Island Areas (PRIA) in 2018. A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems at each of the islands/atolls in the PRIA. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0-30 m depth range. The stratification scheme included island, reef zone, and depth. Sampling effort was allocated based on strata area and sites were randomly located within strata. Sites were surveyed using photo-quadrats along transects to collect benthic imagery (30 photos per site) to ultimately produce estimates of relative abundance (benthic cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness. However, this package only contains the aforementioned images and all analysis data is archived elsewhere. The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than sampling more transects at a site. Therefore, site-level estimates and site to site comparisons should be used with caution. |
