Figure F1. Strontium isotope results vs. calculated age, Site 1103. Solid circles = 262.63 mbsf; open squares = 262.98 mbsf. X- and y-axis error bars represent combined timescale and analytical 2- errors. Gray lines represent the best-fit age and 95% confidence limits of the LOWESS fit to the marine Sr isotope curve of Howarth and McArthur (1997).
