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...

The influence of early diagenesis on trace element and molybdenum isotope geochemistry

Creator:: Poulson, Rebecca L.
Abstract:: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

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...

Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

Creator:: Muratli, Jesse M.
Abstract:: Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

Influence of a Sedimentary Source of Nd on Deep Ocean εNd Distributions

Creator:: Abbott, April N.
Abstract:: Ocean circulation is an important component in Earth's climate system. Predicting future climate and circulation changes requires an improved understanding of the past relationship between climate and ocean currents. The neodymium isotope composition (εNd) of water masses is frequently used as a quasi-conservative tracer to reconstruct ocean circulation. The current...

Evidence of work engagement and its link to performance in lean manufacturing implementation

Creator:: Fairman, Zachary J.
Abstract:: Work engagement is demonstrated when employees are involved with, committed to, enthusiastic, and passionate about their work. The goal of this study was to summarize relevant information on work engagement, produce a working coding system to identify evidence of work engagement, and discuss the implications of work engagement on an...

Hydrothermal links between ocean plateau formation and global anoxia at the Cenomanian-Turonian boundary

Creator:: Snow, Laura J.
Abstract:: The Cretaceous was a period of extreme climatic conditions accompanied by major perturbations in ocean-atmosphere biogeochemical cycles. One of the most intriguing features is the sporadic interruption of normal marine pelagic sediment deposition by organic rich sediments deposited during oxygen-deficient conditions (ocean anoxic events OAEs). A current model for the...

Contribution of cold seep barite to the barium geochemical budget of a marginal basin

Creator:: McQuay, Erica L.
Abstract:: Large barite (BaSO4) structures mark cold seeps in the southern San Clemente Basin. Barium flux to San Clemente sediments is two to three times greater than fluxes measured in surrounding California Borderland basins. Analyses of sediment trap material, water column samples, sediments and pore water indicate that expected bariumbearing mineral...

Leg 202 synthesis: Southeast Pacific paleoceangraphy

Creator:: Tiedemann, Ralf and Mix, Alan C.
Abstract:: Ocean Drilling Program (ODP) Leg 202 has opened a new window into understanding late Paleogene and Neogene global environmental change by providing high-quality sediment sequences from a previously unsampled region, the eastern South Pacific. Eleven sites (1232– 1242) that record variations on timescales ranging from decades to tens of millions...

Leg 204 synthesis : gas hydrate distribution and dynamics in the Central Cascadia accretionary complex

Creator:: Tréhu, Anne Martine, Torres, Marta E., Bohrmann, G., and Colwell, Frederick
Abstract:: Ocean Drilling Program (ODP) Leg 204 to Hydrate Ridge, located on the continental slope offshore Oregon (USA), was the first drilling expedition dedicated to understanding gas hydrate processes in accretionary complexes and provided a testbed for a number of different techniques for estimating the gas hydrate content of sediments. It...
