Abstract:

The data include stable carbon isotope ratios (δ13C) from bulk organic matter in core PS51/154-11. Freeze-dried, homogenized sediments were acidified with 1.5 M HCl in silver boats and then dried in an oven at 55 ˚C. δ13C values were measured using a Thermo Scientific FLASH 2000 CHNS Analyser coupled with a Thermo DeltaQ IRMS via CONFLO IV.
