Figure F31. Shipboard correlation of Sites 1233, 1234, and 1235 based on biostratigraphic (<260 ka for all sites) and magnetostratigraphic (e.g., location of Laschamp Event at ~41 k.y.) evidence as well as long-term patterns in magnetic susceptibility, organic carbon, and calcium carbonate concentrations. These data suggest that all three sites will contain viable records of century- to millennial-scale climate change. IU = instrument units.
