The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

Title: | Benthic Images Collected from Stratified Random Sites (StRS) across the Northwestern Hawaiian Islands (NWHI) in the Papahānaumokuākea Marine National Monument from 2015-07-30 to 2015-08-21. (NCEI Accession 0276273) |
Abstract: | The data described here are the 2015 benthic habitat imagery (color-corrected photographs) from benthic photo-quadrat surveys conducted along transects at stratified-random sites (StRS) across the Northwestern Hawaiian Islands (NWHI) from 2015-07-30 to 2015-08-21 during the Papahānaumokuākea Marine National Monument (PMNM)-led 2015 Reef Assessment and Monitoring Program (RAMP) cruise to the NWHI. 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. 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. |
