Abstract

Benthic foraminiferal assemblages of 237 high-quality surface sediment samples from the South Atlantic Ocean, including the Atlantic sector of the circumpolar ocean, were quantitatively analyzed. Comparisons between assemblages of live and dead specimens showed that potential fossil assemblages of dead specimens were markedly impoverished in fragile and non-resistant agglutinated forms compared to the living assemblages. The dead material was grouped into nine principal faunal end-members by multivariate statistics and quantitatively correlated with available environmental variables. This data set is planned to serve as a reference for interpreting benthic foraminifera fluctuations in Pleistocene Southern Atlantic core material and to constrain the reliability of proxies directly derived from benthic foraminiferal shell geochemistry.
