Introduction
The supplementary data set provided in file "ts01.xlsx" contains the input matrix and principal component analysis solution presented in the main manuscript. FORC diagrams were measured using a Princeton Measurements Corporation VSM at the Australian National University. Central ridges were extracted from calculated FORC distributions using the approach of Egli et al. 2010 (doi:10.1029/2009GC002916). The principal component analysis was calculated using the "princomp" function within the MATLAB statistics toolbox. Only the leading two principal components are provided. 
1. ts01.xlsx FORC central ridges and PCA solution
1.1 Columns labeled "Bc [mT]" refer to the FORC distribution coercivity.
1.2 Worksheet "Central ridges" provides the FORC central ridges as a function of Bc for each of the sites included in the study.
1.3 Worksheet "PCA Solution" provides the scores and loadings of the leading two principal components with respect to location and Bc.
