'event' is the core, 'depth' is the midpoint distance each sediment sample was taken from the top of the core in cm, 'age' is the calibrated age in both years before present and in common era calendar years, '# Diatoms' is the number of diatoms in each 0.5 mL sample to be measured, 'Si 28 concentration' is the measured total concentration of silicon-28 in each 0.45 mL sample aliquot in µg/L, 'blank corrected Si' is the total silicon-28 concentration minus the average blank value in µg/L, 'SiO2/diatom' is the blank corrected silicon-28 concentration scaled up from 0.45 mL to 0.5 mL, scaled from Si to SiO2, and divided by the number of diatoms per sample in ng, 'isoutlier' identifies values more than three scaled median absolute deviations from the median.
