Supplement 2. Age-depth models for Raven, Uchugrak, Poktovik, and Little Isac lakes, including Monte Carlo boot-strapped confidence intervals.

File List LI07AgeDepthData.csv PO07AgeDepthData.csv RA07AgeDepthData.csv UC07AgeDepthData.csv Description Each file contains the output data from the program MCAgeDepth (Higuera et al. 2009, Ecological Monographs, 79:201–219), used to create Fig. 2 in the main text. File names reference site codes: LI (Little Isac), PO (Poktovik), RA (Raven), and UC (Uchugrak). Columns are as follows: Top depth of sample [cm] Calibrated age at sample top [cal yr BP] Upper 95% confidence intervals for data in column two. Lower 95% confidence intervals for data in column two. Sedimentation rate [cm/yr] Upper 95% confidence intervals for data in column five. Lower 95% confidence intervals for data in column five. Sample resolution [yr/sample] Upper 95% confidence intervals for data in column eight. Lower 95% confidence intervals for data in column eight. Missing values: none.
