Title: National Coral Reef Monitoring Program: Benthic Images Collected from Stratified Random Sites (StRS) across the Main Hawaiian Islands from 2019-04-21 to 2019-10-31 (NCEI Accession 0211063)
Abstract: The data described here are benthic habitat imagery (color-corrected 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 April 21 to October 31, 2019 during the ESD-led NCRMP mission around the main Hawaiian Islands.

A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems of Hawaii. 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 in all regions, as well as habitat structure type in the Main Hawaiian Islands. Allocation of sampling effort was proportional to strata area and variance in coral density. Sites were surveyed using photo-quadrats along transects to collect benthic imagery to ultimately produce estimates of relative abundance (percent cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.

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.
