| Zusammenfassung |
| We present the δ18O measurements corresponding to the upper 450 cm of the Central
Mediterranean deep-sea core CT85-5. The detailed radiocarbon chronology of this core,
which is based on the analysis of foraminifera shells, is reported in Hajdas et al. (2011). This
chronology shows regular features, but a reversal in 14C ages appears, corresponding to a
layer containing the deposit of the Campanian Ignimbrite (~ 40 kyr cal BP) that overlaps
with the layer where an enhanced 10Be concentration in sediment was found (Castagnoli et
al. 1995). Due to this feature of the core, a reliable calibration of δ18O profile was obtained
only for the last 270 cm.
The comparison between our δ18O profile and Mediterranean and high latitudes records,
including North Atlantic sediments and Greenland ice cores, will be discussed.
