Down-core magnetic profiles for 16 discrete samples across the PETM for ODP Hole 1263C. a–c Published bulk sediment carbon isotope, carbonate content, and Fe concentration (X-ray fluorescence measurements)4. d, e Bulk Ms, f Mrs/Ms, g bulk coercivity, h bulk coercivity of remanence, i hard IRM plotted on a carbonate-free basis (HIRM-CFB), j S-ratio, k–m IRM-CFB coercivity components, n fitted B1/2 and o DP values for the biogenic magnetite component from IRM curves. Left: Core photo of the PETM interval in Hole 1263C40. Horizontal dashed lines and stars indicate positions of the three samples with magnetic properties presented in Fig. 2, and detailed TEM observations presented in Fig. 4. Grey bars mark different stages across the PETM. Arrows in e, m, n, o are visual guides for data trends
