Weblagoons in southern Sri Lanka, to assess their geochemical composition, their source, and subsequent environmental impacts. Principal component analysis of the tsunami sediments shows that 42% of the total variance is accounted for calcium oxide and Sr. That is, the tsunami deposits are rich in biogenic phases derived from shallow marine sediments. WebThe formal name for this approach of rotating data such that each successive axis displays a decreasing amount of variance is known as Principal Components Analysis, or PCA. PCA produces linear combinations of the original variables to generate the axes, also known as principal components, or PCs.
