The high correlation and statistical similarity between the measurement series in Lake C2 permitted the construction of a composite thickness series. Two composite indices composed of unfiltered and filtered data were constructed by averaging the index values from cores C2-8, 83, 84 and 85. The data was filtered by replacing couplets identified as turbidites with the series mean. Measurements from up to three cores contributed to each value in the final 3300 year composite indices with the majority derived from two cores.
