Logging data are measurements of physical properties of the formation surrounding a borehole, acquired in situ after completion of coring (wireline logging) or during drilling (Logging-While-Drilling, LWD). The range of data (resistivity, gamma radiation, velocity, density, borehole images,…) in any hole depends on the scientific objectives and operational constraints.

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.

dives.These data will be valuable for a comparison with proposed Site KK-03B in the Kerala-Konkan Basin (see Geological setting of the Kerala-Konkan Basin, below) and other monsoon-dedicated IODP expeditions.The proposed site in the Kerala-Konkan Basin provides the opportunity to recover colocated oceanic and terrestrial records for monsoon and premonsoon Cenozoic climate in the eastern Arabian Sea and India, respectively.The site is located on a bathymetric high immediately north of the Chagos-Laccadive Ridge and is therefore not affected by strong tectonic, glacial, and nonmonsoon climatic processes that affect fan sites fed by Himalayan rivers.The cores are expected to consist of a continuous sequence of foraminifer-rich pelagic sediments with subordinate cyclical siliciclastic inputs of fluvial origin from the Indian Peninsula for the Neogene and a continuous paleoclimate record at orbital timescales into the Eocene and possibly the Paleocene.

Laurel B. Childress Carlos A. Alvarez Zarikian A. Briais K.A. Dadd J.-M. Deng

The Vibration Isolated Television Optic Fiber equipment provides visual observation of the seafloor during reentry of an existing borehole. An altimeter mounted to the frame provides accurate height of the VIT frame above the seafloor. An underwater color camera with pan, tilt, and zoom functionality is used for surveying the seafloor and examining mechanical devices.
