171B Preliminary Report Figures

Figure 5. Susceptibility (bold line) and color (lighter line) in a series of 25-m panels that cover part of the mid-late Eocene section recovered at Site 1052. Both measurements show variability with a wavelength of ~1 m, which probably reflects variations in the Earth-Sun orbital geometry (Milankovitch cycles) that will be investigated post-cruise for use in cyclostratigraphy and orbital timing. Note that the color code is (L*a*b) times -1 to facilitate comparison to magnetic susceptibility data.
