Marine Bioregions of the Southwest Pacific - Marine and Coastal Biodiversity Management in Pacific Island Countries (MACBIO)

Zip file containing shapefile and metadata for reef-associated bioregions of the Southwest Pacific Ocean. Thirty, mainly physical, environmental variables were assessed to be adequately comprehensive and reliable to be included in the analysis. These data were allocated to over 140,000 grid cells of 20x20 km across the Southwest Pacific. K-means and then hierarchical cluster analyses were then conducted to identify groups of analytical units that contained similar environmental conditions. The number of clusters was determined by examining the dendrogram and setting a similarity value that aligned with a natural break in similarity.
