description: The file contains 11 worksheets: The "Splice" worksheet provides Anhysteretic Remanent Magnetization (ARM@30mT) data obtained from u-channels collected from core sections of holes U1471A, U1471C and U1471D. The experiments were carried out at the Institute of Astronomy and Geophysics of the University of São Paulo using the triaxial cryogenic magnetometer (2G, mod. 755). The "XRF Scan Data" worksheet contains the results obtained by XRF Scan measurements taken at 1 cm intervals directly on the surface of the divided half-core section (each 1.5 m long) using an Avaatech XRF-Scanning generation at the Ocean Discovery Program (IODP) International Gulf Coast Repository at Texas A&M University. Results are displayed in counts per second. The "Benchtop vs. scanner XRF data" worksheet contains data from discrete measurements in conventional XRF performed on 42 samples collected at each 3 cm interval of the central section U1471C-1H-3W (3 to 4.5 mbsf). The samples, taken in 5 g aliquots of core material, were dried and pulverized in an agate mortar. Powder samples were measured in the conventional XRF Rigaku Supermini200 from the University of São Paulo. The worksheet also presents the average of the XRF scan data for the corresponding depth of each discrete sample. The "1st age model (Sr vs LR04)" worksheet contains the Sr/sum data and the tie points obtained by correlating the Sr/sum data with the LR04 curve (Lisiecki and Raymo; 2005). The "Data with 1st age model" worksheet contains the Fe/sum and ln (Fe/Si) data linearly interpolated to a resolution of 1 kry (using the first age model) and their respective spectral analysis through the Multitaper method using Acycle software. The "2nd age model (Fe vs. NHSI)" worksheet shows the Fe/sum data linearly interpolated to 1 kry (using the first age model) and the Fe/sum data filtered using a bandpass in the precession frequency range. The worksheet also presents the tie points obtained by comparing the filtered Fe/sum data with the insolation curve for the Northern Hemisphere. The "Data with 2nd age model" worksheet contains the Fe/sum and ln (Fe/Si) data linearly interpolated to a resolution of 1 kry (using the second age model) and their respective spectral analysis through the Multitaper method using Acycle software. The "3rd age model (U1471 vs. U1467)" worksheet contains the tie points obtained by correlating the Sr/sum curves of records U1471 and U1467 and their respective ages. The "Data with 3rd age model" worksheet contains the Fe/sum and ln (Fe/Si) data linearly interpolated to a resolution of 1 kry (using the third age model) and their respective spectral analysis through the Multitaper method using Acycle software. The "Normalized data (Zmean)" worksheet contains the Fe/sum and ln (Fe/Si) data normalized to the mean equals zero and standard deviation equals one (that is, zero-mean normalization). The "Normalized data (Zmean)" worksheet contains the Fe/sum and ln (Fe/Si) data normalized to the mean equals zero and standard deviation equals one (that is, zero-mean normalization). The "Detrended data (anomaly)" worksheet contains the detrended Fe/sum and detrended ln (Fe/Si) data. Zmean normalized Fe/sum and ln Fe/Si data were linearly interpolated to a resolution of 500 years. The detrended Fe/sum data was obtained by subtracting LR04 from the Fe/sum record and the detrended ln (Fe/Si) data was obtained by subtracting NHSI from the ln (Fe/Si) record. The worksheet also presents the spectral analysis obtained through the Multitaper method using Acycle software.
