Os isotope ratios of Late Eocene sediments from the tropical Pacific
High resolution records (ca. 100 kyr) of Os isotope composition (187Os/188Os) in bulk sediments from two tropical Pacific sites (ODP Sites 1218 and 1219) capture the complete... -
Stable oxygen isotope ratios of marine barite from Cenozoic sediments
We report new data on oxygen isotopes in marine sulfate (delta18O[SO4]), measured in marine barite (BaSO4), over the Cenozoic. The delta18O[SO4] varies by 6x over the Cenozoic,... -
Bromine and iodine concentrations in sediments and pore fluids of ODP Leg 112
At the Peruvian convergent margin, two distinct pore fluid regimes are recognized from differences in their Cl- concentrations. The slope pore fluids are characterized by low... -
Late Pliocene stable oxygen isotope and Mg/Ca record, and paleotemperature re...
The onset of Northern Hemisphere Glaciation (NHG) ~2.7 Ma ago coincided with prominent climate changes in the tropical regions such as the African and the Asian monsoons.... -
Major element concentrations in spinel, olivine and pyroxene from peridotites...
Serpentinized spinel peridotites of the Newfoundland margin drilled during ODP Leg 210 at Site 1277 have preserved, relic mineral compositions similar to the most depleted... -
Re-OS and Pb isotope ratios of sediments from Saanich Inlet, Western Canada
Re-Os and Pb-Pb isotopic analysis of reduced varved sediments cored in the deeper basin of Saanich Inlet (B.C.) are presented. From core top to 61 cm down-core, spanning... -
Geochemisty and Re-Os isotope ratios of peridotites from ODP Hole 209-1274A f...
Comprehensive major-, trace-element and rhenium-osmium (Re-Os) isotope data are presented for abyssal peridotites from Ocean Drilling Program (ODP) Leg 209, in the North... -
Contents, partition, and isotopic composition of sulphur in sediments from OD...
We have determined (1) the abundance and isotopic composition of pyrite, monosulphide, elemental sulphur, organically bound sulphur, and dissolved sulphide; (2) the partition of... -
Organic geochemistry of deep sea sediments from the Nankai Trough and the Sou...
Earth's largest reactive carbon pool, marine sedimentary organic matter, becomes increasingly recalcitrant during burial, making it almost inaccessible as a substrate for... -
Rare earth element data for sediments from ODP Leg 127
The relative effects of paleoceanographic and paleogeographic variations, sediment lithology, and diagenetic processes on the recorded rare earth element (REE) chemistry of... -
Stable isotope composition of O, H, S, and C from serpentinites of the Marian...
The Mariana and Izu-Bonin arcs in the western Pacific are characterized by serpentinite seamounts in the forearc that provide unique windows into the mantle wedge. We present... -
Chemical and isotopic compositions of altered MORB from ODP Holes 187-1154A, ...
Boron and Pb isotopic compositions together with B-U-Th-Pb concentrations were determined for Pacific and Indian mantle-type mid-ocean ridge basalts (MORB) obtained from shallow... -
Element concentrations of aluminosilicate components from ODP sites in the Pa...
We measured major and trace element concentrations in the operationally defined, chemically extracted, residual aluminosilicate component of sediment from Ocean Drilling Program... -
Magnetic observation of ODP Site 152-919 in the Irminger Basin, North Atlantic
Component natural remanent magnetizations derived from u-channel and 1-qcm discrete samples from ODP Site 919 (Irminger Basin) indicate the existence of four intervals of... -
Chlorine stable isotopic composition of basement fluids from ODP Leg 168 sites
This paper presents chlorine stable isotope compositions (delta37Cl) of sediment pore waters collected by squeezing sediment cores from the sediment-basement interface along an... -
Geochemistry of Hawaiian volcanics
The "Ko'olau" component of the Hawaiian mantle plume represents an extreme (EM1-type) end member of Hawaiian shield lavas in radiogenic isotope space, and was defined on the... -
Rock magnetic susceptibility of ODP Leg 204 sites
Mineral magnetic results and electron microscope observations from gas hydrate-bearing marine sediments cored at southern Hydrate Ridge during Ocean Drilling Program Leg 204... -
Dust flux in the eastern equatorial Pacific
Atmospheric dust levels may play important roles in feedbacks linking continental source areas, tropical convection, marine productivity, and global climate. These feedbacks... -
Sedimentology and Cd/Ca ratios of benthic foraminifera from ODP Site 172-1060...
The Western Boundary Undercurrent (WBUC), off eastern America, is an important component of the Atlantic Meridional Overturning circulation and is the principal route for... -
Sedimentology, planktonic foraminifera distribution and stable isotope compos...
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...
