The record may be analyzed as charcoal accumulation rates or concentration.

Charcoal accumulation rates are in units of pieces cm^-2 year^-1, and often referred to as 'CHAR'. CHAR is calculated as sedimentation rate * charcoal concentration, or [(D_base-D_top)/(Age_base-Age_top)]*(count/volume), where D_base and D_top are the depths of the base and top of each section and Age_base and Age_top are the ages of the base and top of each section.

Use the pop-up menu to select which time series to use for all subsequent analyses. CHAR is the default.
