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>...

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 : 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...

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...

Color Reflectance Spectroscopy : a tool for rapid characterization of deep-sea sediments

Creator:: Mix, Alan C., Rugh, W., Pisias, Nicklas G., Veirs, S., and Leg 138 Scientific Party
Abstract:: During ODP Leg 138, we tested a prototype instrument, developed at Oregon State University, for measuring light reflectance in 511 channels of the visible and near-infrared bands. The technique of reflectance spectroscopy has been used for some time in chemistry and mineralogy (e.g., Hunt, 1977; Gaffey, 1986) and has found...

Paleoceanography of the Eastern Equatorial Pacific during the Neogene : synthesis of Leg 138 drilling results

Creator:: Pisias, Nicklas G., Mayer, Larry A., and Mix, Alan C.
Abstract:: The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change during the Neogene. Two north south transects were drilled (95° and 110°W) within the region of equatorial divergence driven upwelling (and thus high accumulation rates and resolution) and spanning the major...

A summary of ODP leg 141 hydrogeologic, geochemical and thermal results

Abstract:: The subduction of the oceanic spreading center at the Chile Triple Junction is marked by a substantial thermal perturbation and marked changes in the hydrogeologic and aqueous geochemical regimes in the overthrust plate. Ridge subduction substantially changes the fluid chemistry in the wedge through variably hydrating the oceanic basement, accretionary...

Creator:: Mix, Alan C., Tiedemann, R., and Blum, P.
Abstract:: More than 7 km of long and relatively continuous sediment sequences from 11 sites in the southeast and equatorial Pacific were recovered during Leg 202 for the study of the Earth’s climate and biogeochemical systems on scales that range from tectonic (millions of years) to orbital (tens to hundreds of...

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...
