National Coral Reef Monitoring Program: Stratified Random Surveys (StRS) of Coral Demography (Adult and Juvenile Corals) across the Pacific Remote Island Areas since 2014

Metadata Updated: February 27, 2019

The data described here result from benthic coral demographic surveys for two life stages (juveniles, adults) across the Pacific Remote Island Areas since 2014. 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 condition including bleaching and disease.

A two-stage stratified random sampling (StRS) design was employed to survey the coral reef ecosystems of the Pacific Remote Island Areas. 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 the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) led National Coral Reef Monitoring Program (NCRMP) missions since 2014 to the islands and atolls of the Pacific Remote Island Areas, including Baker, Howland, Jarvis and Wake Islands, Johnston and Palmyra Atolls, and Kingman Reef.
