Identification Information

Title:

National Coral Reef Monitoring Program: Stratified random surveys (StRS) of coral demography (adult and juvenile corals) across the Northwestern Hawaiian Islands from 2015-07-30 to 2015-08-21 (NCEI Accession 0184909)

Abstract:

The data described here result from benthic coral demographic surveys for two life stages (juveniles, adults) across the Northwestern Hawaiian Islands from July 30 to August 21, 2015. The data provide information on juvenile and adult coral abundance (density, proportion occurrence, and total colony abundance), size distribution, partial mortality, prevalence and abundance of recent mortality and cause, prevalence of disease and bleaching, and diversity. Juvenile colony surveys include morphology and size. Adult colony surveys record morphology, colony size, partial mortality in two categories - old dead and recent dead, cause of recent dead partial mortality, and non-lesion forming conditions including bleaching and disease. A two-stage stratified random sampling (StRS) design was employed to survey the coral reef ecosystems throughout the region. 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 belt transects to collect juvenile and adult coral colony metrics. 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. The data were collected as part of Papahānaumokuākea Marine National Monument funded research cruise to the Northwestern Hawaiian Islands in 2015. These data are funded separately from but are complementary to coral demographic data collected during National Coral Reef Monitoring Program (NCRMP) missions led by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) across the Hawaiian Archipelago.
