Depth ranges of calcareous nannofossil datums from ODP Holes 113-689B and 113...
Magnetostratigraphic studies of Paleogene sediments piston-cored on Maud Rise, Weddell Sea (ODP Sites 689 and 690), are a cornerstone of Southern Ocean Paleogene and Neogene... -
Sr/Ca ratios of coccoliths from the Paleocene-Eocene Thermal Maximum
During the Paleocene-Eocene Thermal Maximum (PETM), rapid release of isotopically light C to the ocean-atmosphere system elevated the greenhouse effect and warmed temperatures... -
Carbon and oxygen isotopic compositions of Cibicidoides spp. and fine fractio...
A prominent middle Eocene warming event is identified in Southern Ocean deep-sea cores, indicating that long-term cooling through the middle and late Eocene was not monotonic.... -
Carbon and oxygen isotope data for carbonates and benthic foraminifers from O...
At Ocean Drilling Program Site 689 (Maud Rise, Southern Ocean), d18O records of fine-fraction bulk carbonate and benthic foraminifers indicate that accelerated climate cooling... -
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... -
Strontium isotope data from DSDP Sites 32-305 and 62-463 and ODP Sites 113-68...
Fluctuations in oxygen (d18O) and carbon (d13C) isotope values of benthic foraminiferal calcite from the tropical Pacific and Southern Oceans indicate rapid reversals in the... -
Census of calcareous nannofossil taxa expressed as percent of total number of...
Quantitative analysis of upper Eocene-upper Oligocene calcareous nannofossil assemblages from five Ocean Drilling Program sites in the Atlantic and Indian Ocean sectors of the... -
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... -
Mg/Ca ratios of Cenozoic benthic foraminifera from the Indian and South Atlan...
We investigate the evolution of Cenozoic climate and ice volume as evidenced by the oxygen isotopic composition of seawater (delta18Osw) derived from benthic foraminiferal Mg/Ca... -
Neodymium isotope record of late Paleocene to eraly Eocene fish teeth
High-resolution, fish tooth Nd isotopic records for eight Deep Sea Drilling Project and Ocean Drilling Program sites were used to reconstruct the nature of late Paleocene-early... -
Strontium isotope geochemistry of ODP Leg 113 sites
The concentration of dissolved Sr and the distribution of 87Sr/86Sr isotope ratios in Leg 113 interstitial waters may be interpreted in terms of mixing of Sr from four different... -
Strontium isotope ratios of middle Eocene to Oligocene sediments from Maud Ri...
A 87Sr/86Sr isotope curve of the middle Eocene to Oligocene was produced from analysis of foraminifera in Ocean Drilling Program Hole 689B, Maud Rise, near the coast of... -
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,... -
Calcareous dinoflagellates in Maastrichtian-Tertiary sediments of ODP Hole 11...
The distribution of calcareous dinoflagellates has been analysed for the Maastrichtian-Miocene interval of Ocean Drilling Project Hole 689B (Maud Rise, Weddell Sea). The... -
Magnetobiostratigraphy and stable isotope record of Paleocene sediments from ...
Surface and deep water circulation patterns in the eastern Indian Ocean during the Paleocene Epoch are inferred based on an integrated magnetobiostratigraphic and stable isotope... -
Upper Cretaceous planktic foraminiferal biozonation for the Austral Realm
A new planktic foraminiferal zonal scheme is presented for subdivision of Upper Cretaceous pelagic carbonate sequences in the circum-Antarctic region. Definition of the zones... -
Planktic foraminifera across the Cretaceous-Tertiary transition in the Antarc...
Three Antarctic Ocean K/T boundary sequences from ODP Site 738C on the Kerguelen Plateau, ODP Site, 752B on Broken Ridge and ODP Site 690C on Maud Rise, Weddell Sea, have been... -
Miocene diatom biostratigraphy of the Atlantic sector of the Southern Ocean
Four ODP sites located between 64°S and 41°S in the eastern Atlantic sector ofthe Southern Ocean were investigated to refine the Miocene diatom biostratigraphic zonation tied to... -
