Figure F48. Magnetic susceptibility (MS) and CaCO₃ through the Paleocene–Eocene transition at the shallow to deep transect. The MS graphs represent both point magnetic susceptibility (PMS) data measured on the split core and loop sensor (MSL) data measured on the whole core. For correlation of these two methods, 1-cm resolution PMS data were linearly interpolated at 2.5-cm resolution, after which a linear expansion formula was calculated and PMS values were normalized to MSL values: MSL = 2.0683 x PMS + 7.8257 (R² = 0.9885). For Site 1263, MS data from Hole 1263C are spliced with data from Hole 1263D at 335.88 meters composite depth (mcd). Sample depths for Hole 1263D were normalized to Hole 1263C mcd using a linear expansion based on PMS correlation through the P/E transition: Hole 1263C mcd = Hole 1263D mcd x 1.383 – 128.45. For Site 1262, sample depths of CaCO₃ data from Hole 1262A (Core 208-1262A-13H) were normalized to Hole 1262B mcd using a linear expansion based on PMS correlation through the lower part of the P/E transition: Hole 1262B mcd = Hole 1262A mcd x 1.1343 – 18.785 (R² = 0.996; only for data below 139.95 mcd). At Site 1266, CaCO₃ data from Hole 1266B (Section 208-1266B-6H-7) give way to Hole 1266C values at 306.56 mcd. LO = last occurrence, FO = first occurrence.
