Principal Component Analysis (PCA) of IRD content in Heinrich Event layers (H1-H6) and interlayers (I1-I5) of sediment core GeoB18530-1
The data matrix of 192 classified IRD count data from H1-H6 and I1-I5 (excluding I6 because of too low IRD counts) by 22 IRD lithologies (https://doi.pangaea.de/10.1594/PANGAEA.971280) was row-normalized to 100% to give equal weight to all IRD assemblages independently of their specific IRD abundanc...

The data matrix of 192 classified IRD count data from H1-H6 and I1-I5 (excluding I6 because of too low IRD counts) by 22 IRD lithologies (https://doi.pangaea.de/10.1594/PANGAEA.971280) was row-normalized to 100% to give equal weight to all IRD assemblages independently of their specific IRD abundance, but not column-normalized in order to limit the influence of rare, statistically less relevant IRD lithologies.
