Figure F40. Depth-scale representation of the magnetic susceptibility (MS) record at Site 1265 between 278.9 and 294.8 mcd (early Eocene, 53.3 to 53.9 Ma). Assuming an average sedimentation rate of ~2.1 cm/k.y., the energy bands centered on the 0.5- and 2.5-m scale may be linked to precession and eccentricity forcing, respectively. The 1-m energy band might be linked to obliquity. Modulations in the energy bands are probably related to slight changes in sedimentation rates.
