Expansions of coastal upwelling spots along the Brazilian coast were previously reported for Marine Isotope Stage (MIS) 5, but open questions remain regarding the climatic mechanisms and the periodicity of such changes. Based on two marine sediment c

Publikováno v: The Journal of Foraminiferal Research. 47:56-69
The purpose of this study is to evaluate the abundance and preservation state of the tests of Hoeglundina elegans , with the goal to propose a new preservation index for deep-sea sediments. In seawater, aragonite is more soluble than calcite; the ben

Calcareous microfossils have potential in the biostratigraphy of Pleistocene sediments and a clear relationship with paleoceanographic studies. Conversely, there are few quantitative biostratigraphic studies of chronologically-tuned events or section
