Oligocene and lowermost Miocene diatom stratigraphy and datums of ODP Site 19...
Completion of studies on material collected during Ocean Drilling Program Leg 199 at Site 1220 in the equatorial Pacific allows calibration of the ranges of >35... -
Foraminiferal Mg/Ca and Mn/Ca ratios across the Eocene-Oligocene transition
Constraining the magnitude of high-latitude temperature change across the Eocene-Oligocene transition (EOT) is essential for quantifying the magnitude of Antarctic ice-sheet... -
Magnesium isotope ratios of pore-fluids and dolomites
Magnesium concentrations in deep-sea sediment pore-fluids typically decrease down core due to net precipitation of dolomite or clay minerals in the sediments or underlying... -
Radiolarian biostratigraphy and chronology of radiolarian events of ODP Leg 1...
A generally rich radiolarian fauna ranging in age from Quaternary to early Eocene (Zone RP7) was found at five of the eight sites drilled during Ocean Drilling Program (ODP) Leg... -
Organic carbon, freely extractable lipids and ketone recovery of ODP Leg 199 ...
Six samples from Sites 1219 and 1221 ranging in age from early Eocene to early Oligocene were analyzed for freely extractable lipids to determine whether the low organic carbon... -
Phosphorus components and barite in untreated and in carbonate-free sediments...
We determined changes in equatorial Pacific phosphorus (µmol P/g) and barite (BaSO4; wt%) concentrations at high resolution (2 cm) across the Paleocene/Eocene (P/E) boundary in... -
Accumulation rates, carbon composition and Eocene carbonate compensation dept...
CaCO3, Corg, and biogenic SiO2 were measured in Eocene equatorial Pacific sediments from Sites 1218 and 1219, and bulk oxygen and carbon isotopes were measured on selected... -
Geochemistry and sedimentation rates of ODP Leg 199 sites and of surface sedi...
We present the first high-resolution organic carbon mass accumulation rate (MAR) data set for the Eocene equatorial Pacific upwelling region, from Sites 1218 and 1219 of the... -
Chemical composition of bulk sediments from ODP Hole 199-1221C
A record of inorganic geochemical variability was produced from a contiguous sequence of 35 samples, with 1 cm spacing, recovered from Hole 1221C. This record covers from 153.91... -
Chemical composition of bulk sediments from ODP Hole 199-1215A
Elemental concentrations were determined on 21 samples from Hole 1215A to evaluate the influence of hydrothermal sources on bulk sediment composition. Rare earth element (REE)... -
Chemical composition of ferromanganese micronodules and bulk sediments from O...
Distribution, size, mineral, and chemical compositions of ferromanganese micronodules (FMMNs) and chemical composition of host sediments were examined in a series of red clay... -
Late Eocene-early Oligocene radiolarian events and abundances in ODP Leg 199 ...
During Ocean Drilling Program Leg 199, eight sites (Sites 1215-1222) were cored in the Central Pacific. Late Eocene-early Oligocene thick radiolarian-rich biogenic sediments... -
Relative abundances of selected radiolarian species in sediments of ODP Leg 1...
During Ocean Drilling Program (ODP) Leg 199, sediments were recovered from eight sites in the Central Pacific. Late Oligocene and early Miocene radiolarians are common to... -

We investigated Oligocene and early Miocene benthic foraminiferal faunas (> 105 µm in size) from Ocean Drilling Program (Leg 199) Site 1218 (4826 m water depth and ~3300 to... -
Stratigraphic correlation of ODP Site 199-1218 and 199-1219
During Ocean Drilling Program Leg 199 a high-resolution (~1-2 cm/k.y.) biogenic sediment record from the late Paleocene to the early Miocene was recovered, containing an... -
Stable isotope record, Mg/Ca ratios and age model of St. Stephens Quarry, Ala...
In the largest global cooling event of the Cenozoic Era, between 33.8 and 33.5 Myr ago, warm, high-CO2 conditions gave way to the variable 'icehouse' climates that prevail... -
