Geochemistry of rare earth elements in basalts from Walvis Ridge
Selected basalts from a suite of dredged and drilled samples (IPOD sites 525, 527, 528 and 530) from the Walvis Ridge have been analysed to determine their rare earth element... -
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... -
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... -
Stable isotope composition of early Danian sediments from the Atlantic Ocean
A long-standing question in Paleogene climate concerns the frequency and mechanism of transient greenhouse gas-driven climate shifts (hyperthermals). The discovery of the... -
Total number of benthic foraminifera in sediments below the K/T boundary in t...
Most species of Late Cretaceous deep-sea benthic foraminifera are believed to be cosmopolitan and therefore to exhibit only minor biogeographical differences. In this... -
Paleocene and Eocene nannofossil datums from Shatsky Rise and Walvis Ridge
The precision of late Paleocene to middle Eocene nannofossil datums is investigated by means of quantitative methods and correlated to the magnetic polarity stratigraphy, using... -
Contusotruncana contusa abundances and morphotypes in the cretaceous mid-lati...
Spatial and temporal patterns in test size and shape (test conicity and spiral roundness) and absolute abundance (accumulation rate) of the planktonic foraminifer... -
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... -
Stable carbon and oxygen isotope record of Maastrichtian sediments from DSDP ...
The upper Maastrichtian interval of mid-latitude South Atlantic Deep Sea Drilling Project site 528 spans approximately the last 4 million years of the Cretaceous. The isotopic... -
Sedimentology and planktonic foraminiferal dissolution during the latest Cret...
A high-resolution (10-20 kyr) record of variations in CaCO3 content and dissolution was established for latest Cretaceous (last 0.7 Myr) deep-sea sediments from the South... -
Characterization of late Campanian and Maastrichtian planktonic foraminiferal...
Depth habitats of 56 late Cretaceous planktonic foraminiferal species from cool and warm climate modes were determined based on stable isotope analyses of deep-sea samples from... -
Planktic foraminiferal assemblage turnover at the Cretaceous-Tertiary boundary
Three uppermost Cretaceous through basal Paleocene stratigraphic sequences are examined for planktic foraminiferal assemblage stability and temporal succession patterns. These... -
Stable carbon and oxygen isotope ratios across the Cretaceous/Tertiary boundr...
The isotopic composition and diversity of nannofossils were studied in cores from the Deep Sea Drilling Project (DSDP) Sites 525A, 527, 528, and 529 from the Walvis Ridge, South... -
Latitudinal variation in the planktic foraminifer Contusotruncana contusa in ...
The morphological variability (coiling properties, size and shape) of the planktic foraminifer Contusortuncana contusa (Cushman) in the terminal Cretaceous ocean was examined at... -
Maastrichtian planktic foraminifera of the South Atlantic Ocean
Stratigraphic, faunal and isotopic analyses of the Maastrichtian at DSDP sites 525A and 21 in the South Atlantic reveal a planktic foraminiferal fauna characterized by two major... -
Planktonic foraminifera in the latest Maastrichtian of Walvis Ridge, South At...
An abrupt global warming of 3-4°C occurred near the end of the Maastrichtian at 65.45-65.10 Ma. The environmental effects of this warm event are here documented based on stable... -

Fluorescence of dissolved organic matter un marine sediments
The fluorescence of porewaters from marine sediment cores from six different areas was measured. In most cases, fluorescence was affected primarily by the diagenesis of organic... -
(Appendix 1) 87Sr/86Sr ratios of planktonic foraminifera from DSDP Hole 74-528
87Sr/86Sr values for standards equal 0.710265 for NBS 987, and 0.709175 for seawater samples from the North Atlantic and Central Pacific. Ratios are fractionation corrected to... -
Strontium isotope ratios of planktonic foraminifera from sediment samples acr...
Seawater 87Sr/86Sr values increase abruptly by 28 * 10**-6 across the Cretaceous/Tertiary boundary (KTB). This small, but rapid shift is superimposed on the larger scale...
