Temperature Reconstruction at Iceberg Lake

Reconstructed melt season temperatures from the Bagley Icefield region based on Iceberg Lake varve thickness (V). Temperatures (thick curve) are presented as anomalies from the reconstructed A.D. 442 to A.D. 1998 mean and have been smoothed with a 40-year low pass filter. Thin curves are 95% confidence intervals. Regression based upon temperature reconstruction (TD) of Davi et al. (2003) where TD = 9.857 + 0.264 * ln(V). r2 = 0.09, p = 0.000.
