Calcium isotopic composition of planktonic foraminifera from ODP Site 154-925
An 18 million year record of the Ca isotopic composition (d44/42Ca) of planktonic foraminiferans from ODP site 925, in the Atlantic, on the Ceara Rise, provides the opportunity... -
Accumulation and composition of terrigenous material on Ceara rise over the p...
Ceara Rise, located east the Amazon River mouth, is covered with a thick blanket of pelagic carbonate and hemipelagic terrigenous sediment. The terrigenous component has been... -
Revision of the early-middle Pleistocene calcareous nannofossil biochronology
The extant nannofossil biostratigraphic and biochronologic framework for the early-middle Pleistocene time interval has been tested through the micropaleontological analysis of... -
Stable carbon and oxygen isotope ratios of foraminifera from the latest Mioce...
We present a detailed study of menardellid speciation, abundance and coiling changes between 6.34 and 5.1 Ma (latest Miocene and earliest Pliocene). Menardellids are widely... -
Carbonate preservation reconstructed from ODP Sites 154-927 and 154-929 at Ce...
Enhanced Atlantic overturning during the Pliocene was first proposed almost 10 yrs ago. Evidence for this Pliocene super conveyor scenario has been collected using a number of...
