Figure F170. Split-core inclinations, declinations, and intensities after 25-mT demagnetization for Holes 1256C and 1256D. Also shown are the principal component analysis inclinations, which are not biased in the interval near 310 mbsf like the single 25-mT inclinations are. The bias is probably caused by magnetic noise in the form of an anhysteretic remanent magnetization imparted to the sample as it passes through the in-line AF demagnetizer.
