HCBC 2019 Hawaii Bleaching Analysis Ready Clustered Data

Published by Pacific Islands Fisheries Science Center | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 10, 2026 at 06:01 AM | Dataset Last Updated: January 01, 2021 at 12:00 AM
The analysis-ready data described here result from performing hierarchical clustering of individual coral bleaching surveys conducted across the Hawaiian Archipelago in 2014, 2015, and 2019. In order to resolve issues of spatial autocorrelation, the surveys were grouped into distinct clusters with a spatial resolution of 1km. The data was stratified across depths to generate metrics for up to three depth bins per cluster: shallow (0-6m), mid (>6-18m), and deep (>18m). This dataset contains environmental data paired for all 2019 observations, used to analyze drivers of the coral bleaching event. No environmental drivers data is included for 2015 and 2014 observations, as the data from these bleaching events was solely used in a temporal analysis comparing the 2014/2015 events to the 2019 event. This dataset also contains weights assigned to each observation (all years) for use in the drivers, temporal and spatial analyses.
