Biological productivity, foraminiferal isotopic and elemental records from the shallow depths of western South Atlantic during the Holocene

Here we present the elementary composition, stable, and radiogenic isotope records of foraminifera from the continental shelf sediments influenced by upwelling events in the western South Atlantic during the Holocene. Millennial-scale oscillation records of organic carbon flux were obtained by the Benthic Foraminifera Accumulation Rate (BFAR) index and compared to the trace and rare earth element concentrations in foraminifera from the sediment trap F-150#3 and the sediment core CF10-01. Stable isotopes (d13C and d18O) of Cibicides kullenbergi and neodymium isotopes of foraminifera were also applied to understand the paleoceanographic settings during the last 9 ka.
