National Coral Reef Monitoring Program: Methodological Case Study for 'Downscaling Ecological Trends from the Spatially Randomized Datasets' in the Main Hawaiian Islands, 2005-2016

Description

The data described here result from the application of a down-scaling method to NOAA National Coral Reef Monitoring Program (NCRMP) benthic cover data, in an attempt by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD) to make NCRMP data maximally useful to reef managers. ESD scientists took benthic cover data from the Main Hawaiian Islands from 2005-2016 and applied a statistical technique based on contiguous clustering and mixed model analysis to discover an optimal reporting sector for NCRMP data (Oliver et al 2020). Specifically, clusters were identified based on NCRMP benthic cover data collected by ESD from 4 survey methods (towed diver, line point intercept, and photoquadrat surveys in which benthic images were analyzed either using CoralNet or CPCe) and then the optimal size and number of spatial sectors was assessed to generate reporting sector assignments that balanced minimal size against maximal ecological homogeneity and statistical power. These assignments are recorded in the dataset along with the source benthic cover observations, including live hard coral cover, soft coral cover, crustose coralline algae cover, macroalgal and turf algae cover, sediment cover, and all other categories are binned into "other".

0 Zip file containing a shapefile of the selected down-scaled reporting sectors resulting from the analysis. The zip file contains the required files that comprise a shapefile, including .shp (main file that stores the feature geometry), .shx (index file that stores the index of the feature geometry, and .dbf (dBASE table that stores the attribute information of features). Additional files provided with the shapefile include .prj (stores the coordinate system information), .sbn and .sbx (the 2 files that store the spatial index of the features), .xml (metadata for ArcGIS—stores information about the shapefile), and the optional .cpg (specifies the codepage for identifying the characterset to be used). The additional and optional files were all autogenerated by ArcGIS. When viewing the shapefile in any ArcGIS application, you will only see one file representing the shapefile; use Windows Explorer to view all the files associated with the shapefile. https://accession.nodc.noaa.gov/0211127
