Foraminifera stable isotopes (δ13C and δ18O), and Mg/Ca-based temperatures from a Holocene sediment core obtained southwest off the Cabo Verde archipelago (MUC5)

This dataset provides absolute abundance data of planktonic foraminifera (identified at the species level) and benthic foraminifera and radiolaria (both counted as total numbers). The microfossils were obtained from a sediment core collected at 4394 m water depth off the Cabo Verde archipelago which covers most of the Holocene Epoch. Counts were performed on the >150 µm sediment fraction, with a minimum of 300 planktonic foraminifera specimens per sample. Combined stable isotopes (δ13C and δ18O) and Mg/Ca ratios are included for the surface-dwelling planktonic foraminifera Globigerinoides ruber albus (G. ruber sensu stricto morphotype following Wang, 2000) and the sub-thermocline dwelling Globorotalia truncatulinoides from the 315-400 μm sediment fraction. Al/Ca, Fe/Ca and Mn/Ca measurements to monitor potential test contamination are also provided. Additionally, this dataset contains δ13C and δ18O for the epibenthic foraminifera Cibicidoides wuellerstorfi.
