    "title": "National Coral Reef Monitoring Program: Benthic Images Collected from Stratified Random Sites (StRS) across the Mariana Archipelago from 2022-04-12 to 2022-08-10 (NCEI Accession 0279441)",
    "description": "The data described here are benthic habitat imagery that result from benthic photo-quadrat surveys conducted along transects at stratified random sites across the Mariana Archipelago from April 12 to August 10, 2022 as a part of Rapid Ecological Assessment (REA) surveys for corals and fish.\n\nA stratified random sampling (StRS) design was employed to survey the coral reef ecosystems across the Marianas. 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 to ultimately produce estimates of relative abundance (benthic cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.\n\nThe 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.",
