Thickness and duration of biostratigraphic zones, assemblages, ages and sedim...
In this Initial Report of the Deep Sea Drilling Project, detailed studies of Sites 533 (gas hydrates) on the Blake Outer Ridge and 534 (oldest ocean history) in the Blake-Bahama... -
Carbonate, organic carbon, pyrolysis and composition of the extracts at DSDP ...
The geochemical studies of Sites 534 and 391 and their comparison allow us to improve the chemical characterization of different geological formations dating from the early... -
Organic geochemical characteristics at DSDP Holes 76-534A and 44-391C
Pyrolysis assay, bitumen analysis, and elemental analysis of kerogen were used to characterize the organic matter of selected core samples from Hole 534A (Leg 76) and Hole 391C... -
Highly dealkylated copper and nickel etioporpyfrins in marine sediments
Copper porphyrins have been recognized as natural constituents of marine sediments only within the past 5 years (Palmer and Baker, 1978, Science201, 49–51). In that report it... -
Mineral and chemical compositions of sedimentary and volcano-sedimentary rock...
Sedimentary cover on the bottom of the Northwest Atlantic Ocean is underlain by Late Jurassic - Cretaceous tholeiite-basalt formation. It consists of come sedimentary formations... -
Strontium and oxygen isotope data for DSDP Hole 44-390A and ODP Leg 171 holes
Differences in regional responses to climate fluctuations are well documented on short time scales (e.g., El Niño-Southern Oscillation), but with the exception of latitudinal... -
Occurrence of hiatuses PH and NH 1 through NH 7 in DSDP holes
Miocene paleoceanographic evolution exhibits major changes resulting from the opening and closing of passages, the subsequent changes in oceanic circulation, and development of... -
Depth, age, strontium isotopic ratios and trace elemental ratios of samples f...
Large variations exist between published mid-Cretaceous (late Barremian to early Turonian stages) seawater Sr-isotope stratigraphies; this has resulted in disparate... -
Early Maastrichtian stable isotopes: changing deep water sources in the North...
We propose that the observed short-term stable isotope fluctuations reflect changes in high- and low-latitude intermediate to deep water sources, based on a high-resolution... -
Dinoflagellate cysts of the Early Cretaceous North Atlantic Ocean
Early Cretaceous dinoflagellate cysts were reinvestigated from nine deep-sea sites of the North and Central Atlantic. In general the zonation scheme developed for the western... -
Benthic foraminiferal abundances in Late Cretaceous sediments of the Tethys
Benthic foraminiferal distribution patterns throughout the late Maastrichtian Tethyan deep sea are analyzed. Many species are ubiquitously distributed throughout this region and... -
Size-related isotopoc trends in Maastrichtian planktic foraminifera
The serial test dissection and sieve fraction methods for determining the pattern of size-related change in oxygen and carbon isotopic ratios are compared using four Late... -
Foraminifera and microfossil occurence in Late Jurassic sediments of the Nort...
Biostratigraphical, taxonomical, and palaeocological results were obtained from Oxfordian to Tithonian foraminifers of the Northern and Southern Atlantic Ocean boreholes of the... -
Diversity and faunal composition of benthic foraminifera in Hole 44-390A on t...
Benthic foraminiferal assemblages are a widespread tool to understand changes in organic matter flux and bottom-water oxygenation and their relation to paleoceanographic changes... -
