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