Supplemental materials for "Can freeze-thaw cycles erase traces of fire use? An experimental approach to understanding combustion residues preservation"

This is the supplementary material for Murphree et al., Can freeze-thaw cycles erase traces of fire use? An experimental approach to understanding combustion residues preservation. This includes: Macrodata_Update_CM - measured data from each of the experimental replicates* analysis.R - R code for the statisical analysis of the Macrodata_Update_CM, including graphics SI Sample Prep & Results - word document outlining the sample production methods, moisture content protocol, Measurement procedure, results of the statisitical analysis, and variation of the surface ash layers immediately after freezing** SI FTIR Spectra - FTIR procedure and results for the experimental sediments *Abbrevations used: Position B= Buried, S= Surface; Layer A=Ash, C=Charcoal; Water=Moisture content, 1 = 100%, 0.5= 50%, 0 = 0%; Nb_Cy = Number of Cycles, Avg= Average thickness; stdev= Standard Deviation; cofvariation = coefficient of variation **Abbrevation used: FTC = Freeze-thaw Cycles; Moisture = Moisture content
