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... -
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geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated.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... -
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 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 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... -
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... -
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... -
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... -
Compilation of 220 sediment core δ¹³C data from the glacial Atlantic Ocean
We compare a compilation of 220 sediment core d13C data from the glacial Atlantic Ocean with three-dimensional ocean circulation simulations including a marine carbon cycle... -
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...
