    • HCBC 2019 Hawaii Bleaching Analysis Ready Clustered Data

    Metadata Updated: December 13, 2025

    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.

    Lineage Coral bleaching surveys were conducted during the 2014/2015 and 2019 thermal stress events in the Hawaiian Archipelago. In order to avoid spatial autocorrelation in subsequent analyses, hierarchical clustering was performed to group survey data 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). Transformed and scaled weights were assigned per cluster based upon the inverse of the standard error of mean percent bleaching.
