Bulk stable carbon and oxygen isotopes from ODP Site 1258, and Fe intensities...
Timing is crucial to understanding the causes and consequences of events in Earth history. The calibration of geological time relies heavily on the accuracy of radioisotopic and... -
Siliceous phytoplankton in middle Eocene sediments of ODP Hole 207-1260A
The Middle Eocene diatom and silicoflagellate record of ODP Site 1260A (Demerara Rise) is studied quantitatively in order to throw light on the changes that siliceous... -
Tie points and log-adjusted depth scales for ODP Leg 207 Sites
Multiple copies of Cretaceous black shales extending from the early Cenomanian to the end of the Santonian were recovered at five sites on Demerara Rise during Leg 207 of the... -
Consolidation properties and hydraulic conductivities of sediments from ODP L...
The stress history, permeability, and compressibility of sediments from Demerara Rise recovered during Ocean Drilling Program Leg 207 were determined using one-dimensional... -
Carbon and nitrogen composition and isotope ratios of bulk and decarbonated s...
Organic carbon, total nitrogen, carbonate carbon, and carbonate oxygen isotopic compositions were measured for 95 samples selected from the black shale sequences drilled during... -
Major, trace and rare earth element concentrations of sediments from ODP Leg ...
The Cretaceous and Paleogene sediments recovered during Ocean Drilling Program Leg 207 can be divided into three broad modes of deposition: synrift clastics (lithologic Unit V),... -
Stable oxygen and carbon isotope ratios of foraminifera and test results afte...
We report oxygen and carbon stable isotope analyses of foraminifers, primarily planktonic, sampled at low resolution in the Cretaceous and Paleogene sections from Sites 1257,... -
Abundance estimates of diatoms in ODP Leg 207 sediments
Twenty-eight core catcher samples were provided to the author by the shipboard party for evaluation of fossil diatoms. Samples are from Ocean Drilling Program Leg 207 Holes... -
Silicoflagellate abundances in sediments of ODP Leg 207 sites
The Ocean Drilling Program (ODP) drilled at five sites in the western Atlantic Ocean during Leg 207. The objective of the drilling was to recover samples from the shallow buried... -
Magnetostratigraphy of ODP Leg 207 sediments
Ocean Drilling Program (ODP) Sites 1257-1261 recovered thick sections of Upper Cretaceous-Eocene oceanic sediments on Demerara Rise off the east coast of Surinam and French... -
Cenomanian benthic foraminifera of Demerara Rise
This study is based on Cenomanian sediments of Ocean Drilling Program (ODP) Sites 1258 and 1260 from Demerara Rise (Leg 207, western tropical Atlantic, off Suriname, ~1000 and... -
Turonian to Coniacian planktic foraminiferal assemblages of ODP Site 207-1259
Abundance patterns of planktic and benthic foraminifera from a tropical Atlantic drill site (Ocean Drilling Program Site 1259, Demerara Rise, Suriname margin) display a... -
Calcareous nannofossil assemblages of Ocean Anoxic Event 2 in ODP Sites 207-1...
The calcareous nannofossils of the Cenomanian/Turonian boundary interval of Sites 1258 and 1260 (Ocean Drilling Program Leg 207) have been studied in order to understand the... -
Cretaceous stable isotopic record and sea surface temperture estimation for O...
The Turonian (93.5 to 89.3 million years ago) was one of the warmest periods of the Phanerozoic eon, with tropical sea surface temperatures over 35°C. High-amplitude sea-level... -
Stable organic carbon isotope record and total organic carbon content from th...
Ocean Drilling Program (ODP) Leg 207 recovered expanded sections of organic-carbon-rich laminated shales on Demerara Rise (western tropical Atlantic). High-resolution organic... -
Stable oxygen isotope record and benthic foraminiferal abundances in Cretaceo...
During the mid-Cretaceous period, the global subsurface oceans were relatively warm, but the origins of the high temperatures are debated. One hypothesis suggests that high sea... -
Eocene sedimentary calcium carbonate contents and stable isotope composition ...
'Hyperthermals' are intervals of rapid, pronounced global warming known from six episodes within the Palaeocene and Eocene epochs (~65-34 million years (Myr) ago) (Zachos et... -
Geochemistry of Albian to Santonian black shale sequences on the Demerara Ris...
Ocean Drilling Program Leg 207 recovered thick sequences of Albian to Santonian organic-carbon-rich claystones at five drill-sites on the Demerara Rise in the western equatorial... -
