Foraminiferal, lithic, and isotopic changes across four major unconformities ...
Sediment samples taken at close intervals across four major unconformities (middle Miocene/upper Miocene, lower Oligocene/upper Oligocene, lower Eocene/upper Eocene, lower... -
A sedimentological, faunal, and isotopic record of the middle-to-late Pliocen...
Hydraulic piston coring at DSDP Site 548, on the upper continental slope southwest of Ireland, recovered a nearly complete Pliocene section spanning 103 m of sediment. The... -
Benthic foraminifera extinctions in the Cenozoic record
In the late Pliocene-middle Pleistocene a group of 95 species of elongate, cylindrical, deep-sea (lower bathyal-abyssal) benthic foraminifera became extinct. This Extinction... -
Stable carbon and oxygen isotope record of planktonic foraminifera across the...
The early Cenozoic marine carbon isotopic record is marked by a long-term shift from high d13C values in the late Paleocene to values that are 2 to 3 lower in the early Eocene.... -
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... -
Calcareous dinoflagellate cycst in the mid-Cenomanian Boreal realm
A transect from the bathyal to proximal shelf facies of the Boreal Realm was investigated to compare spatial and temporal distribution changes of calcareous dinoflagellate cysts... -
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geochronologic knowledge, the originally published age models for many older deep sea marine sections have become badly outdated.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... -
Upper Eocene to Oligocene strontium, carbon and oxygen isotope record of DSDP...
We improved upper Eocene to Oligocene deep-sea chronostratigraphic control by integrating isotope (87Sr/86Sr, delta18O, delta13C) stratigraphy and magnetostratigraphy. Most... -
Construction of a precise early Eocene orbital cyclostratigraphy for DSDP Sit...
We constructed a precise early Eocene orbital cyclostratigraphy for DSDP Site 550 (Leg 80, Goban Spur, North Atlantic) utilizing precession related cycles as represented in a... -
Age model and elemental data of DSDP Holes 48-401 and 80-549
A growing body of geologic evidence suggests that emplacement of the North Atlantic Igneous Province (NAIP) played a major role in global warming during the early Paleogene as... -
Oxygen and carbon isotopic composition in Eocene and Oligocene planktonic and...
Oxygen and carbon isotope ratios in Eocene and Oligocene planktonic and benthic foraminifera have been investigated from Atlantic, Indian, and Pacific Ocean locations. The major... -
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... -
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 ratios and paleoceanaographic reconstructions from sediment co...
Largely continuous millennial-scale records of benthic d18O, Mg/Ca-based temperature, and salinity variations in bottom waters were obtained from Deep Sea Drilling Project Site... -
Paleomagnetic of the Paleocene/Eocene boundary interval in DSDP holes from th...
A magnetostratigraphic reinvestigation of the Paleocene/Eocene boundary intervals in DSDP Holes 550 and 549, Goban Spur, has removed uncertainties associated with the previously... -
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... -
Changes in calcareous nannofossil assemblages across the Paleocene/Eocene tra...
Quantitative analyses of selected calcareous nannofossils in deep-sea sections recovered from the paleo-equatorial Pacific (ODP Leg 199) provide new information about... -
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... -
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...
