Latest Cretaceous to early Eocene nannofossil of ODP Site 198-1209
The Chicxulub bolide impact 66 million years ago drove the near-instantaneous collapse of ocean ecosystems. The devastating loss of diversity at the base of ocean food webs... -
Reconstruction of dust flux of ODP Hole 198-1209C
Eolian dust in pelagic deep sea sediments can be used to reconstruct ancient wind patterns and paleoenvironmental response to climate change. Traditional methods to determine... -
Calcareous nannofossils and planktic foraminiferal assemblages of ODP Hole 19...
Calcareous nannofossil and planktic foraminiferal assemblages from ODP Hole 1210A in the northwestern Pacific Ocean were used to reconstruct surface-water conditions for the... -
Lead isotopic ratios of Barremian-Aptian marine sediments
We present initial isotopic ratios of lead for Early Cretaceous (Barremian-Aptian) sections from Shatsky Rise (Pacific) and Gorgo a Cerbara (Italy). Our Pb isotopic data track... -
Maastrichtian calcareous nannofossils of the Indian Ocean and Shatsky Rise
The biotic effects of volcanism have long been the unknown factors in creating biotic stress, and the contribution of the Deccan volcanism to the K-T mass extinction remains... -
Paleomagnetic characterization and age of several ODP Leg 198 sites, Shatsky ...
Shatsky Rise, a medium-sized large igneous province in the west Central Pacific Ocean, has three main topographic highs that preserve a thick sedimentary record from Cretaceous... -
Age and petrographic characterization of volcanic ash from ODP Leg 198 and Le...
In this study of volcanic ash retrieved from Shatsky Rise during Ocean Drilling Program Leg 198, the texture and composition of the volcanic components (glass and crystals) were... -
Calcareous nannofossil biostratigraphy of ODP Hole 198-1208A sediments, Shats...
Ocean Drilling Program Site 1208 was drilled on the Central High of Shatsky Rise, and a highly expanded Neogene section (320 m), an extremely condensed Paleogene fragment (6.01... -
Lithology and geochemistry of ODP Leg 198 sites, Shatsky Rise
Samples of chert, porcellanite, and chalk/limestone from Cretaceous chert-bearing sections recovered during Leg 198 were studied to elucidate the nature and origin of chert... -
Mineralogy and petrographic summary of ODP Leg 198 sites and DSDP Hole 62-463...
This petrological study of the lower Aptian Oceanic Anoxic Event (OAE1a) focused on the nature of the organic-rich interval as well as the tuffaceous units above and below it.... -
Revised composite depth scales for ODP sites 198-1209, 198-1210 and 198-1211,...
We present new revised composite depth scales for Ocean Drilling Program Leg 198 Sites 1209, 1210, and 1211, drilled at Shatsky Rise in the western Pacific Ocean.... -
Sand fraction, foraminifer isotopic composition and foraminifer element ratio...
Stable oxygen and carbon isotope measurements (d18O and d13C) of planktonic and benthic foraminifers were conducted to assess the temperature history and circulation patterns... -
Carbonate and barite content accross the Eocene/Oligocene boundary of ODP Leg...
The barite and CaCO3 content (in weight percent) of marine sediments can be used to determine spatial and temporal changes in export production (organic and carbonate carbon... -
Foraminifer, coarse fraction and carbonate characteristics of sediments from ...
Holes 1209A and 1211A on Southern High, Shatsky Rise contain expanded, nearly continuous records of carbonate-rich sediment deposited in deep water of the equatorial Pacific... -
Planktic foraminiferal assemblages in sediments of four ODP Leg 198 holes
A pulse of intense carbonate dissolution occurred during the early late Paleocene at 58.4 Ma. A prominent 5 to 25 cm-thick dark brown clay-rich calcareous nannofossil ooze was... -
Mineral and foraminifer composition of sediments across the Paleocene/Eocene ...
The Paleocene/Eocene Thermal Maximum (PETM) was a transient interval of global warming ~55 m.y. ago associated with transformation of ecosystems and changes in carbon cycling.... -
Benthic foraminifera across the Cretaceous/Paleogene boundary in ODP Hole 198...
Deep-sea benthic foraminifera show important but transient assemblage changes at the Cretaceous/Paleogene (K/Pg) boundary, when many biota suffered severe extinction. We... -
Size variations of Discoaster multiradiatus across the Paleocene-Eocene therm...
Size measurements of the calcareous nannofossil taxon Discoaster multiradiatus were carried out across the Paleocene-Eocene Thermal Maximum (PETM) in Ocean Drilling Program... -
Calcareous nannofossil species richness across the Paleocene-Eocene Thermal M...
The Paleocene-Eocene Thermal Maximum (PETM, ~5 million years ago) was an interval of global warming and ocean acidification attributed to rapid release and oxidation of buried... -
Biomarkers of early Aptian sediments of the Shatsky Rise
This study investigates organic-rich sedimentary sequences deposited during the early Aptian Oceanic Anoxic Event (OAE1a) at Sites 1207 and 1213 on Shatsky Rise (ODP Leg 198) in...
