Pacific Reef Assessment and Monitoring Program: Stratified random surveys (StRS) of coral demography and condition across the Northwestern Hawaiian Islands from 2007-09-21 to 2012-08-19 (NCEI Accession 0184869)

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 cruises to the Northwestern Hawaiian Islands in 2007, 2009, 2011 and 2012.

These data were funded separately from but are complementary to coral demographic data collected during NOAA's Pacific Reef Assessment and Monitoring Program (Pacific RAMP) missions led by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (formerly the Coral Reef Ecosystem Division) across the Pacific Islands Region from 2008 to 2012.
