Mineralogy, geochemistry and elemental ratios of ODP Core 171B-1049C-8X
Inorganic geochemistry and mineralogy of Core 171B-1049C-8X, containing a Cretaceous/Tertiary boundary section, was investigated by X-ray fluorescence (XRF) and X-ray... -
Iron X-ray fluorescence (XRF) scannings of ODP Holes 165-1001A and 171-1050C
Abstract: Ocean Drilling Program Sites 1001A (Caribbean Sea) and 1050C (western North Atlantic) display obliquity and precession cycles throughout polarity zone C27 of the late... -
Stable isotope and Mg/Ca ratios of Paleogene benthic foraminifera in the west...
Global cooling and the development of continental-scale Antarctic glaciation occurred in the late middle Eocene to early Oligocene (~38 to 28 million years ago), accompanied by... -
Late Albian foraminiferal carbon and oxygen isotope data and biostratigraphic...
A late Albian-early Cenomanian record (~103.3 to 99.0 Ma), including organic-rich deposits and a d13C increase associated with oceanic anoxic event 1d (OAE 1d), is described... -
Isotope measurements from late Paleocene - early Eocene of 5 cores from Atlan...
High-resolution stable carbon isotope records for upper Paleocene - lower Eocene sections at Ocean Drilling Program Sites 1051 and 690 and Deep Sea Drilling Project Sites 550... -
Early Cenozoic Atlantic and Pacific benthic foraminiferal isotopes from 12 sites
Oxygen and carbon isotope records are important tools used to reconstruct past ocean and climate conditions, with those of benthic foraminifera providing information on the deep... -
Helium isotope ratios and sedimentation rate models of ODP holes
A continuous age model for the brief climate excursion at the Paleocene-Eocene boundary has been constructed by assuming a constant flux of extraterrestrial 3He (3He[ET]) to the... -
Latest Paleocene-earliest Eocene cyclostratigraphy
I present a new method for reconnaissance cyclostratigraphic study of continuously cored boreholes: the generation of detailed sediment color logs by digitizing Ocean Drilling... -
Nd, Sm and carbon isotopic data for samples from ODP Legs 115, 145, 171, and 207
Late Cretaceous fish debris from Demerara Rise exhibits a dramatic positive excursion of 8 e-Nd units during ocean anoxic event 2 (OAE2) that is superimposed on extremely low... -
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... -
Geochemistry of Eocene sediments from ODP Site 171-1052 on the Black Nose, At...
We use an X-ray fluorescence (XRF) Core Scanner to obtain records of elemental concentrations in sediment cores from Ocean Drilling Program (ODP) Leg 171B, Site 1052 (Blake... -
87Sr/86Sr results for the Maastrichtian samples from ODP Leg 171
Analyses of 87Sr/86Sr in foraminifera and sedimentological observations suggest that the Chicxulub impact was not the trigger for slumps or a hiatus within the Maastrichtian... -
Foraminiferal oxygen and carbon isotope data for DSDP Sites 32-305 and 62-463...
Oxygen isotope analyses of well-preserved foraminifera from Blake Nose (30°N paleolatitude, North Atlantic) and globally distributed deep-sea sites provide a long-term... -
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... -
The evolutionary history of size variation of planktic foraminiferal assembla...
The iterative evolutionary radiation of planktic foraminifers is a well-documented macroevolutionary process. Here we document the accompanying size changes in entire planktic... -
Planktonic foraminiferal biostratigraphy and stable carbon isotope ratios of ...
The muricate planktonic foraminiferal genera Morozovella and Acarinina were abundant and diverse during the upper Palaeocene to middle Eocene and dominated the tropical and... -
Determination of sulfite and manganese in sediments from the K/T boundary
The solid-state-physics technique of electron spin resonance (ESR) has been employed in an exploratory study of marine limestones and impact-related deposits from... -
Bulk δ13C and δ18O stable isotope data of ODP Site 171-1053
ODP 1053: bulk δ13C and δ18O Stable isotope dataset: This dataset contains the 13C and 18O isotope data from 70 bulk sediment samples (at 1 cm sampling resolution) from ODP...
