Introduction 14 Igneous petrology 18 Metamorphic petrology 21 Structural geology 26 Geochemistry 33 Microbiology 38 Paleomagnetism 40 Petrophysics 49 References 11 Sum up section recovered lengths and enter as total core recovered; compute percent recovery. 12 Select microbiology sample if appropriate. Designated scientist 13 Wash and space out pieces in split liners; mark "upward" orientation. 14 Reconstruct fractured pieces if possible; shrink-wrap fragile pieces. 15 Add spacers between pieces (no glue yet). 16 Check binning and draw splitting line on each piece; mark working half. Designated scientist 17 Permanently glue spacers in split liner; angle braces point upcore so top of piece is at top of bin. 18 Enter spacer offsets in registry for piece log. 19 Enter final "curated section lengths" in registry. 20 Optionally enter piece lengths in registry for piece log. Designated scientist 21 Image whole-round surface (0°, 90°, 180°, and 270° quarter images). Designated technicians, scientists 22 Prepare whole-round composite images. Imaging specialist 23 Measure gamma ray attenuation (GRA) and magnetic susceptibility loop sensor (MSL) with Whole-Round Multisensor Logger (WRMSL). 24 Measure natural gamma radiation (NGR) with Natural Gamma Radiation Logger (NGRL). 25 Split sections (i.e., split pieces along the lines indicated by designated scientists). 26 Label piece halves. 27 Image dry surface of archive halves with Section Half Imaging Logger (SHIL). 28 Measure reflectance spectroscopy and colorimetry (RSC) and point magnetic susceptibility (MSP) on archive halves with Section Half Multisensor Logger (SHMSL). 29 Macroscopic description of archive half (and working half if needed). 30 Measure paleomagnetic properties on archive halves. Paleomagnetists 31 Measure P-wave velocity on Section Half Measurement Gantry (SHMG). Physical properties specialists 32 Select and flag samples to be taken from working half for shipboard analysis. Designated scientist 33 Cut shipboard and shore-based samples from working-half pieces. Curatorial staff 34 Microscopic description of thin sections. Core describers 35 Inductively coupled plasma-atomic emission spectroscopy (ICP-AES), X-ray diffraction (XRD), and carbon-hydrogen-nitrogen-sulfur (CHNS) analyses. Geochemists 36 Measure paleomagnetic and rock magnetic properties on cube samples. Paleomagnetists 37 Measure moisture and density (MAD) on cube samples. Physical properties specialists 38 Select and flag personal/group samples to be taken from working half for shore-based analysis. Scientists 39 Inspect and approve personal samples. Sample Allocation Committee 40 Cut shipboard and shore-based samples from working-half pieces. Curatorial staff 41 Place archive halves in D-tubes when description and paleomagnetic measurements are complete. Store in refrigerator until shipment to designated IODP core repository (i.e., Kochi Core Center). 42 Bag and pack personal/group samples in boxes for shipment to designated investigator addresses.
