Osmium concentrations and isotope ratios of ODP Site 146-893A, supplement to: Williams, Gwyneth A; Turekian, Karl K (2004): The glacial-interglacial variation of seawater osmium isotopes as recorded in Santa Barbara Basin. Earth and Planetary Science Letters, 228(3-4), 379-389

Gwyneth A Williams & Karl K Turekian
The Pleistocene deposits of Santa Barbara Basin (SBB) show laminations during interglacial periods typical of an anoxic or suboxic depositional environment and more sporadically laminated deposits during glacial times, indicating a more oxic environment of deposition. The 187Os/188Os value of sediment leaches varies as a function of climate, consistent with a more radiogenic Os signal during interglacial times and less radiogenic Os values more typical of glacial times. The signal is confounded by contributions from...

Neodymium isotope ratios of fish teeth from ODP Site 113-689 (Appendix A), supplement to: Scher, Howie D; Martin, Ellen E (2004): Circulation in the Southern Ocean during the Paleogene inferred from neodymium isotopes. Earth and Planetary Science Letters, 228(3-4), 391-405

Howie D Scher & Ellen E Martin
Long-term records of neodymium (Nd) isotopes from sedimentary archives can be influenced by both changes in water mass mixing and continental weathering. Results of Nd isotopic analyses of fossil fish teeth from ODP Site 689 (Maud Rise, Southern Ocean) provide a long, continuous, high-resolution marine sediment Nd isotope record (expressed in epsilon-Nd units). Correlation of down core secular variations between the epsilon-Nd record, delta13C values from benthic foraminifera, and clay mineral assemblages demonstrates that long-term...

Revised geomagnetic polarity timescale for the late Oligocene to early Miocene of ODP Site 177-1090, supplement to: Billups, Katharina; Pälike, Heiko; Channell, James E T; Zachos, James C; Shackleton, Nicholas J (2004): Astronomic calibration of the late Oligocene through early Miocene geomagnetic polarity time scale. Earth and Planetary Science Letters, 224(1-2), 33-44

Katharina Billups, Heiko Pälike, James E T Channell, James C Zachos & Nicholas J Shackleton
At Ocean Drilling Program (ODP) Site 1090 (subantarctic South Atlantic), benthic foraminiferal stable isotope data (from Cibicidoides and Oridorsalis) span the late Oligocene through early Miocene (~24-16 Ma) at a temporal resolution of ~5 ky. Over the same interval, a magnetic polarity stratigraphy can be unequivocally correlated to the geomagnetic polarity time scale (GPTS), thereby providing direct correlation of the isotope record to the GPTS. In an initial age model, we use the newly derived...

Smear slide analysis of sediment core GeoB5836-2, supplement to: Seeberg-Elverfeldt, Ismene A; Lange, Carina Beatriz; Arz, Helge W; Pätzold, Jürgen; Pike, Jennifer (2004): The significance of diatoms in the formation of laminated sediments of the Shaban Deep, Northern Red Sea. Marine Geology, 209(1-4), 279-301

Ismene A Seeberg-Elverfeldt, Carina Beatriz Lange, Helge W Arz, Jürgen Pätzold & Jennifer Pike
Laminated sediments spanning the last 20,000 years (though not continuously) in the Shaban Deep, a brine-filled basin in the northern Red Sea, were analyzed microscopically and with backscattered electron imagery in order to determine laminae composition with emphasis on the diatomaceous component. Based on this detailed study, we present schematic models to propose paleoflux scenarios for laminae formation at different time-slices. The investigated core (GeoB 5836-2; 26°12.61'N, 35°21.56'E; water depth 1475 m) shows light and...

Sedimentology, planktonic foraminifera distribution and stable isotope composition during marine isotope stage 3 of ODP Site 172-1060 in the West Atlantic, supplement to: Vautravers, Maryline J; Shackleton, Nicholas J; López-Martinez, Constancia; Grimalt, Joan O (2004): Gulf Stream variability during marine isotope stage 3. Paleoceanography, 19(2), PA2011

Maryline J Vautravers, Nicholas J Shackleton, Constancia López-Martinez & Joan O Grimalt
We have studied Ocean Drilling Program Site 1060 on the Blake Outer Ridge, which lies beneath the Gulf Stream. We focus on marine isotope stage 3, 60-25 thousand years before present (ka). Sea surface temperatures (SSTs) inferred both from foraminiferal fauna and alkenone ratios, as well as counts of iceberg melt-out debris and benthic stable isotope analyses, enable our record to be interpreted in terms of regional hydrographic changes as well as changing thermohaline circulation...

Mineral, chemical and isotopic compositions of hydrothermally altered sediments from the Middle Valley (Juan de Fuca Ridge), ODP Site 139-858, supplement to: Decitre, Sylvie; Buatier, Martine D; James, Rachael H (2004): Li and Li isotopic composition of hydrothermally altered sediments at Middle Valley, Juan De Fuca. Chemical Geology, 211(3-4), 363-373

Sylvie Decitre, Martine D Buatier & Rachael H James
Li and Li isotopes have been measured in the clay fraction of sediments recovered from the Middle Valley hydrothermal site on the Juan De Fuca Ridge. The Li content of pure detrital clays is 51 ppm while hydrothermal clays and carbonates have lower Li (22+/-11 ppm). However, there is no clear relationship between the mineralogy of the hydrothermal alteration products and their Li content. The d7Li value of the detrital clays is +5.8‰. Hydrothermal clays...

Trace element concentrations and Li isotope composition in DSDP and ODP sediments from island arcs, supplement to: Bouman, Claudia; Elliott, Tim; Vroon, Pieter Z (2004): Lithium inputs to subduction zones. Chemical Geology, 212(1-2), 59-79

Claudia Bouman, Tim Elliott & Pieter Z Vroon
We have studied the sedimentary and basaltic inputs of lithium to subduction zones. Various sediments from DSDP and ODP drill cores in front of the Mariana, South Sandwich, Banda, East Sunda and Lesser Antilles island arcs have been analysed and show highly variable Li contents and d7Li values. The sediment piles in front of the Mariana and South Sandwich arcs largely consist of pelagic sediments (clays and oozes). The pelagic clays have high Li contents...
