Pacific Reef Assessment and Monitoring Program: Belt Transect Surveys for Demographics and Condition of Corals at U.S. Pacific Reefs from 2007 to 2012

The data described here result from benthic coral demographic surveys in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of NOAA's Pacific Reef Assessment and Monitoring Program (Pacific RAMP). Permanent sites located in hard-bottom habitats in 0-30 m depths were surveyed using belt transects to collect adult coral colony metrics, including colony size, partial mortality in two categories - old dead and recent dead, and non-lesion forming condition, including bleaching and disease.

The data provided in this data set were collected during NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) led Pacific RAMP cruises across the Pacific Islands Region from 2008 to 2012.

Data collected as part of Papahānaumokuākea Marine National Monument funded research cruises in the Northwestern Hawaiian Islands in 2007, 2009, 2011, and 2012 are also included as these data were funded separately from but are complementary to the Pacific RAMP data collected by ESD. A two-stage stratified random sampling (StRS) design was employed during these monument-led missions in the Northwestern Hawaiian Islands. 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. 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.
