**Figure F27.** Plots of representative alternating field (AF) demagnetization results for discrete paleomagnetism samples, Site U1409. Upper plots show intensity variation with progressive demagnetization, and lower plots show vector endpoints of paleomagnetism directions on orthogonal vector diagrams (i.e., Zijderveld plots). Vector diagrams indicate reasonably resolved calculate the characteristic remanent magnetization (ChRM) directions for the (A) normal and (B) reversed chrons from the APC core intervals, whereas (C) some samples do not show stable component. Solid circles = horizontal projections, open circles = vertical projections, gray circles = data not used to calculate ChRM direction, black dashed line = ChRM direction. Inc = inclination, Dec = declination, MAD = maximum angle of deviation.
