Info for the Ice data files. 

Ice_Data_Matrix: raw data matrix. 

Ice_Data_Normed_Matrix: means and standard deviations scaled to zero and one, using Ice_Standardize.m (see below)

Ice_Data_Normed_Anova_Matrix: Output from the Bayesian ANOVA package, which adjusts the means such that the records are all expressed as anomalies with respect to the entire interval spanned by the data set. 

Each column a year, given by timeline_ice.
Each row a location, given in Ice_Locs as (lon, lat).

The rows are in the same order as Table S2.

Ice_Standardize.m 
Sets the mean and standard deviations of the longest records to zero and one, respectively, over a common [1400, 1974] interval. For each other record, finds the intersection with the [1400, 1974] interval, finds the means and stds of the longest records over this interval, take averages, and scales the record to match. Note that this is mainly to assure that the variances are roughly the same, as the Bayesian Anova (Tingley, 2012) takes care of differences in the means.
