Estimating lithology from nonintrusive reflectance spectra : Leg 138

Creator:: Mix, Alan C., Harris, Sara E., and Janecek, Thomas R.
Abstract:: During Leg 138, we measured reflectance spectra in the visible and near-infrared bands (455-945 nm) every few centimeters on split core surfaces from eastern tropical Pacific Ocean sediments. Here, we evaluate predictions of the content of biogenic calcite, biogenic opal, and nonbiogenic sediments from the reflectance spectra. For Sites 844...

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...

Data report : isotopic characterization of dissolved inorganic carbon in pore waters, leg 204

Creator:: Torres, Marta E. and Rugh, W. D.
Abstract:: Isotopic characterization of carbon in the dissolved inorganic carbon (DIC) pool is fundamental for a wide array of scientific studies directly related to gas hydrate research. In order to generate integrated and internally consistent data of δ¹³C of DIC in pore waters from Hydrate Ridge, we used the modern continuous...

Late Quaternary paleoceanography in the Eastern Equatorial Pacific Ocean from Planktonic Foraminifiers : a high-resolution record from Site 846

Creator:: Mix, Alan C., Le, J., and Shackleton, N. J.
Abstract:: High-resolution records of δ¹⁸0 and relative abundances of planktonic foraminifers were generated for ODP Leg 138 Site 846 for the past 800 k.y., with an average sampling interval of 3.6 k.y. The time scale was constructed by correlating the benthic δ¹⁸0 record to the SPECMAP and ODP Site 677 δ¹⁸0...

Benthic foraminifer stable isotope record from Site 849 (0 - 5 Ma) : local and global climate changes

Creator:: Mix, Alan C., Pisias, Nicklas G., Rugh, W., Wilson, J., Morey, A., and Hagelberg, T. K.
Abstract:: Benthic foraminifer and δ¹³C data from Site 849, on the west flank of the East Pacific Rise (0°11'N, 110°3l'W; 3851 m), give relatively continuous records of deep Pacific Ocean stable isotope variations between 0 and 5 Ma. The mean sample spacing is 4 k.y. Most analyses are from Cibicides wuellerstorfi>...

Microbial methane generation and gas transport in shallow sediments of an accretionary complex, southern hydrate ridge (ODP Leg 204), offshore Oregon, USA

Creator:: Claypool, George E., Milkov, Alexei V., Lee, Young-Joo, Torres, Marta E., Borowski, Walter S., and Tomaru, Hitoshi
Abstract:: Sediments at the southern summit of Hydrate Ridge display two distinct modes of gas hydrate occurrence. The dominant mode is associated with active venting of gas exsolved from the accretionary prism and leads to high concentrations (15%–40% of pore space) of gas hydrate in seafloor or near-surface sediments at and...

Data report : spectral reflectance observations from recovered sediments

Creator:: Ortiz, Joseph D., O'Connell, Suzanne, and Mix, Alan C.
Abstract:: Sediment spectral reflectance measurements were generated aboard the JOIDES Resolution during Ocean Drilling Program Leg 162 shipboard operations. The large size of the raw data set (over 1.3 gigabytes) and limited computer hard disk storage space precluded detailed analysis of the data at sea, although broad band averages were used...

Data report : major-element chemistry of Hole 896a glass

Creator:: Fisk, Martin R., McNeill, Andrew W., Teagle, Damon A. H., Furnes, Harald, and Bach, Wolfgang
Abstract:: Ocean Drilling Program Hole 896A (1°13.01'N, 83°43.39'W) is in 3440 m of water east of the Galapagos Platform in the equatorial eastern Pacific Ocean. At this site in 5.9 Ma crust, basement rocks were recovered over the depth range of 195.1 meters below seafloor (mbsf) to 469 mbsf. These rocks...

Data report : major and trace element data for leg 202 sites 1233 and 1234

Creator:: McManus, James
Abstract:: The exchange of waters between the Pacific and the Southern Oceans occurs along the eastern boundary of the South Pacific. Because water masses of the Antarctic provide a connection among the world's ocean basins, these water masses maintain the ability to influence changes in ocean circulation and climate (Lynch-Stieglitz et...
