Stach_2026_Fig_S7_p90_values_for_Westerly_maxima.txt

This file contains centred-log ratio (clr) values for Iron (Fe) standardised to z-scores per unit and subunit to account for sedimentological and geochemical differences across units (Toonen et al., 2015). Phases of intensified eolian activity are recognised as values at or above the 90th percentile (p90) threshold (Hobday et al., 2016; Perkins-Kirkpatrick and Lewis, 2020), calculated separately for each unit or subunit, accounting for unit- and subunit-specific backgrounds, and highlighted in the figure by a stripped purple line.
