Age models of upper Pliocene samples of the North Atlantic
Abundance variations of six Pliocene species of discoasters have been analyzed over the time interval from 1.89 to 2.95 Ma at five contrasting sites in the North Atlantic: Deep... -
Stable isotope record of Cibicidoides spp. from early and middle Miocene sedi...
The middle Miocene delta18O increase represents a fundamental change in the ocean-atmosphere system which, like late Pleistocene climates, may be related to deepwater... -
Stable oxygen and carbon isotope ratios of Pliocene benthic foraminifera in t...
Large changes in benthic foraminiferal delta180 and delta13C occurred during the Pliocene (between 3.0 and 2.0 Ma) at Hole 665A. Oxygen isotopic compositions increased to... -
Mid-Pliocene deep-sea bottom water temperatures based on ostracode Mg/Ca ratios
We studied magnesium:calcium (Mg/Ca) ratios in shells of the deep-sea ostracode genus Krithe from a short interval in the middle Pliocene between 3.29 and 2.97 Ma using deep-sea... -
Late Pliocene stratigraphic distribution of Globoconella taxa in the North At...
Quantitative records of Globorotalia puncticulata and Globorotalia inflata, the last two members of the Globorotalia (Globoconella) lineage, obtained from North Atlantic... -

Maceral distribution, stratigraphic position and vitrinite reflectance at DSD...
Twenty-four sediment samples from late Paleocene to early Eocene were studied for maceral content, vitrinite reflectance, and spectral fluorescence in order to determine some... -
Sea surface temperature reconstruction based on dinoflagellates from the Nort...
The application of quantitative and semiquantitative methods to assemblage data from dinoflagellate cysts shows potential for interpreting past environments, both in terms of... -
Secondary mineral assemblages in a volcanic sequence of ODP Hole 104-642E
Mineralogical and geochemical analyses of alteration products from upper and lower volcanic series recovered during ODP Leg 104 reveal variations both in composition and order... -
Chemical characteristics of ash layers from ODP Leg 104
Forty-five volcanic ash horizons cored at Sites 642, 643, and 644 on the Vøring Plateau and ranging in age from early Miocene to Pleistocene, are discussed in terms of their... -
Age models and stable isotope record of sediment cores from the Atlantic Ocean
The high-resolution delta18O and delta13C records of benthic foraminifera from a 150,000-year long core from the Caribbean Sea indicate that there was generally high delta13C... -
Stable isotope record of foraminifera from DSDP Hole 81-552A
It is now widely accepted that expansion of continental glaciers is one manifestation of profound paleoenvironmental change in latest Miocene time. The oxygen isotopic record in... -
Geochemistry of North Atlantic Igneous Province basalts
New Sr-Nd-Pb-Hf data require the existence of at least four mantle components in the genesis of basalts from the the North Atlantic Igneous Province (NAIP): (1) one (or more... -
Stable isotope record of benthic foraminifera in late Pleistocene sediments
Variations in the contribution of North Atlantic Deep Water (NADW), relative to North Pacific Deep Water (NPDW), to the Southern Ocean, are assessed by comparing delta13C... -
Stable carbon and oxygen isotope records of Cibicidoides wuellerstorfi in DSD...
Carbon isotopic records from benthic foraminifera are used to map patterns of deep ocean circulation between 3 and 2 million years ago, the interval when significant northern... -
Stable isotope record of DSDP Hole 81-552A in the northeastern Atlantic Ocean
Oxygen and carbon isotope ratios in benthic foraminifers have been determined at 10 cm intervals through the top 59 m of DSDP Hole 552A. This provides a glacial record of... -
Correlation of Bolboforma zonation and nannoplankton stratigraphy in the Neog...
The Neogene Bolboforma zones established in the North Atlantic have been correlated with the calcareous nannoplankton stratigraphy obtained by investigation of the same samples... -
Integrated stratigraphy of the Messinian across the North Atlantic Ocean
The Messinian was a time of major climatic and paleoceanographic change during the late Cenozoic. It is well known around the Mediterranean region because of the giant...
