Figure F32. Millennial-scale variability at Site 1233. Magnetic susceptibility and diatom abundance plotted on a preliminary age scale for the interval 0 to 45 k.y. The age scale is based on Holocene age control points derived from a correlation of the magnetic susceptibility records between Site 1233 and AMS-14C dated core GeoB 3313-1 (Lamy et al., 2001) and the location of the Laschamp Event. All ages are calendar years are BP and are linearly interpolated between the dates. The data are compared to the GISP2 ice core in Greenland (Grootes et al., 1993) and the Byrd ice core in Antarctica (Bender et al., 1999). SMOW = oxygen isotopic composition of standard mean ocean water.
