Radiocarbon ages of sediment core SK218-1

Radiocarbon ages measured on planktonic foraminifera Globigerinoides ruber alba and stable oxygen isotope and Mg/Ca ratios measured on the same species. For Mg/Ca and d18O measurements shells from the 250-350 micrometer size fraction were used. Mg/Ca measurements are based on 30-40 shells that were cleaned using an oxidative cleaning step. Seawater temperature estimates were calculated using the T = ln(Mg/Ca/0.09)/0.38 following 10.1029/2001GC000200.
