Nd isotope composition obtained on mixed planktonic foraminifera samples from cores MD01-2472, KET82-21, MD90-912, RECORD23 and MD90-917

Radiocarbon dating was undertaken of well-preserved calcareous test samples of planktonic foraminifera (monospecific samples of Globigerinoides ruber, Globigerina bulloides and Globigerina inflata and a mix of planktonic foraminifera for one sample) in the size fraction >150 µm. All AMS 14C dates...

Description
Summary:Radiocarbon dating was undertaken of well-preserved calcareous test samples of planktonic foraminifera (monospecific samples of Globigerinoides ruber, Globigerina bulloides and Globigerina inflata and a mix of planktonic foraminifera for one sample) in the size fraction >150 µm. All AMS 14C dates were converted to calendar years by using the CALIB 7 program (Reimer, 2013) and assuming a mean constant surface ocean reservoir age of ~400 yrs for the Mediterranean Sea. Stable oxygen isotope measurements were performed on 10-20 hand-picked and well-preserved (clean and intact) specimens of the planktonic foraminifera G. bulloides (fraction 250-315 µm). Neodymium isotopes were measured on mixed planktonic foraminifera from the washed >150 µm size fraction of the samples.
