Biogenic sedimentation of DSDP Site 85-574
The equatorial Pacific is an important part of the global carbon cycle and has been affected by climate change through the Cenozoic (65 Ma to present). We present a Miocene... -
Distribution of diatoms in Oligocene to Pleistocene sediments of the tropical...
According to the drilling probes of the Deep Waier Drilling Project, Neogene sediments in a tropical area of the Pacific Ocean are divided into 15 zones based on diatoms. The... -
Calcareous nannofossil biostratigraphy of ODP Hole 108-667A and DSDP Site 85-574
Detailed quantitative analyses of selected calcareous nannofossil species were used to determine the placement of zonal boundaries. In Hole 667A in the equatorial Atlantic... -
Calcium carbonate preservation in the equatorial Pacific
The Pliocene-Pleistocene history of CaCO3 preservation in the central equatorial Pacific is reconstructed from a suite of deep-sea cores and is compared to fluctuations in... -
Revised chronology of Neogene DSDP holes from the World Ocean
After nearly 30 years of growth in geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated. In this... -
Pelagic phosphorus accumulation in the Pacific Ocean
As a limiting nutrient to marine life, phosphorus (P) is an effective tracer of today's marine productivity. The distribution of P in marine sediments likewise tracks the... -
Calcium carbonate global LGM Burial rate data
Global databases of calcium carbonate concentrations and mass accumulation rates in Holocene and last glacial maximum sediments were used to estimate the deep-sea sedimentary... -
Rock magnetism of pelagic sediments from DSDP Leg 85 sites
A detailed rock magnetic investigation has been carried out on Deep Sea Drilling Project (DSDP) pelagic sediments from the Central Equatorial Pacific. This comprises hysteresis... -
Os isotope ratios of sediments from the Eocene-Oligocene boundary
Osmium (Os) isotope analyses of bulk sediments from the South Atlantic, Equatorial Pacific, and the Italian Apennines yield a well-dated and coherent pattern of 187Os/188Os... -
Benthic foraminifera and phytodetritus species in sediments from DSDP Leg 85,...
From late middle Eocene through earliest Oligocene, high-latitude regions cooled, and by the end of the period, continental ice sheets existed in Antarctica. Diversity of... -
Interstitial water chemistry of DSDP Leg 85 sites
The concentration changes in pore waters of dissolved calcium, magnesium, sulfate, strontium, and silica and of alkalinity are controlled by diagenetic reactions occurring... -
Biostratigraphic and paleomagnetic datum levels in sediments from DSDP Site 8...
Data on the composition of benthic foraminiferal faunas at Deep Sea Drilling Project Site 575 in the eastern equatorial Pacific Ocean were combined with benthic and planktonic... -
Sr/Ca ratios of Cenozoic benthic foraminifera
A Cenozoic multi-species record of benthic foraminiferal calcite Sr/Ca has been produced and is corrected for interspecific offsets (typically less than 0.3 mmol/mol) and for... -
Strontium and neodymium isotope data for barite separates and pore waters, an...
Strontium and neodymium isotopic data are reported for barite samples chemically separated from Late Miocene to Pliocene sediments from the eastern equatorial Pacific. At a site... -
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,... -
Late Eocene to Recent deep-sea benthic foraminifera from the Central equatori...
Benthic foraminifers were studied in upper Eocene to Recent core-catcher samples from DSDP Sites 573, 574, and 575. The sites are on a north-south transect from the equator to... -
Age models and stable isotope ratios from the Mid-Miocene
Mid-Miocene pelagic sedimentary sections can be correlated using intermediate and high resolution oxygen and carbon isotopic records of benthic foraminifera. Precision of a few...
