title: IODP Expedition 401 Natural gamma radiation

description: Natural gamma radiation (NGR) data in the ~0.1 to 3.0 MeV range were measured using eight custom-designed sodium iodide (thallium) [NaI(Tl)] detectors arranged along the core measurement axis at 20 cm intervals. The NGR system uses layers of passive shielding (lead) and active shielding (plastic scintillators and coincidence electronics) to reduce the cosmic-ray signal for low-count analysis of sediment core sections and to obtain the maximum signal-to-noise ratio. Data are reported on a total counts per second basis and the raw spectral files are available as compressed files for later analysis.

title: IODP Expedition 401 X-ray image logger (XSCAN)

description: Digital x-ray images were taken of core section whole-rounds (WR) or split section-halfs (SHLF) by the X-ray Image Logger (XSCAN). Each x-ray image was flatfield corrected using a dark calibration image taken with the camera shutter closed and white calibration image taken with the shutter open. The raw image width in pixels was determined by the distance between the calibration right crop and left crop pixels. Multiple scans of the same sample may have been taken at various rotational offsets. The 0 degree position along the rotational axis is the camera oriented vertically facing downward with the sample positioned below. The camera rotates around a stationary sample holder, completes an entire scan, returns to the starting position, rotates, then completes another scan. Scan speed and exposure time are relative and automatically adjust as one or the other are altered prior to a scan. To improve constrast, after each scan pixel intensities are scaled by reshaping the image intensity histogram using the histogram expansion factor and histogram anchor parameters. The operator selects the region-of-interest (ROI) to encompass only the sample material.

title: IODP Expedition 401 X-ray fluorescence (XRF)

description: Elemental peak intensities in section halves were measured by an Avaatech X-ray fluorescence (XRF) Core Scanner postexpedition. Each measurement position may be measured at multiple XRF conditions in order to excite and measure specific ranges of elements (e.g., 10 kV and no filter for light elements). Peak intensity changes (concentrations not provided) are then used to help recognize and define major chemostratigraphic units without the need for destructive sampling. Data are presented in comma-delimited (CSV) files by section and by energy/instrumental conditions.

title: IODP Expedition 401 Whole-round core section composite 360 degree images

description: Images of the outside of hard rock whole-round sections were acquired using a linescan imager (Section Half Imaging Logger [SHIL]) and a special holder that allows each 90 degree segment of the outer surface to be positioned properly. The images were taken at a resolution of 20 lines/mm (50 micropixels). JRSO staff take these quadrant images and compile them into a side-by-side rollout photograph of the section. Composite images are available as both JPG and TIF image formats. Individual quadrant images are available as JPG images only through this report; contact the IODP-JRSO Data Librarian if quadrant TIF files (~160 MB) are needed.

title: IODP Expedition 401 Thermal conductivity

description: Thermal conductivity was measured using the heated needle method in either full-space needle configuration (soft/saturated sediments) or half-space needle configuration (harder materials) of a TeKa Berlin TK-04 thermal conductivity meter. Heat is applied to the sample and then thermal equilibrium is sought. The heating and equilibration curve is reduced to derive the thermal conductivity value. Raw data are stored if a user wishes to do off-line or postexpedition reduction.
