Sediment depth age-models, stable carbon isotope data, and radiocarbon data of Atlantic Ocean sediment cores
Sediment depth age-models, stable carbon isotope data, and radiocarbon data are reported for a suite of sediment cores from Iberian- and Brazil Margins, in the Atlantic basin. The sediment sequences span the last deglaciation (~30,000 years to the present). Stable carbon isotopes were measured on th...

Sediment depth age-models, stable carbon isotope data, and radiocarbon data are reported for a suite of sediment cores from Iberian- and Brazil Margins, in the Atlantic basin. The sediment sequences span the last deglaciation (~30,000 years to the present). Stable carbon isotopes were measured on the benthic foraminifer species Cibicidoides wuellerstorfi, in the Godwin Laboratory, University of Cambridge. Each measurement was run on 1-4 individuals with a combined mass of 50-180μg. Samples were reacted with orthophosphoric acid (100%) and analysed, in comparison with a reference gas, using a dual inlet Thermo MAT 253 mass spectrometer connected to a Kiel device. Radiocarbon dates were obtained on monospecific samples of planktonic foraminifera, Globigerinoides ruber (Brazil Margin) or Globigerina bulloides (Iberian Margin), and samples of mixed benthic foraminifera (excluding agglutinated species) picked from the >150μm size-fraction.
