Figure F14. Variations in paleomagnetic declination (psu) (top), inclination (middle), and normalized relative paleointensity (bottom) at Chile margin, Site 1233, from 0–136 mcd (inferred ~0–140 ka). Note the inferred Laschamp Excursion (~41 ka) near 68 mcd, which implies an average sedimentation rate of nearly 170 m/k.y. from the core top to this level. PSV = paleomagnetic secular variation, BP = before present.
