Orbitally tuned age model of sediment cores 340-TC1, 340-PC1, and 333-PC2 dry bulk density composite section

Cores 333-PC2, 340-TC1, and 340-PC1 were correlated to generate a continuous composite section based on dry bulk density.Magnetic susceptibility profiles (Peck et al., 1994) between cores 333-PC2, 340-TC1, and 340-PC1 along our composite section are generally correlative, indicating our correlation of the cores' physical properties is robust. Our 333-340 composite section was then assigned age by correlating dry bulk density to the orbitally-tuned BDP-96 biogenic silica record (Prokopenko et al., 2006), supplemented by published radiocarbon dates (Peck et al., 1994) and an assumed core top age of 0 ka.
