Water quality assessment of Marine Park Islands in Johor, Malaysia

This study applied agglomerative hierarchical clustering (AHC) and principal component analysis (PCA) to investigate the spatial water quality patterns of Johor islands and identify possible sources of pollution in the Johor Marine Park waters. AHC was applied to 18 sites and grouped them into three...
