| Zusammenfassung |
| At the crossing between low and mid-latitude, NAO and monsoonal influenced climate
systems, the Mediterranean is a crucial site for paleoclimate studies. The Gulf of Taranto,
southern Italy, offers a number of high sedimentation rate sites, ideal for the study of short
time-scale paleoclimate variability in the marine environment. The MOCCHA project aims at
unraveling the main mechanisms forcing the climate in this area by a multi-proxy approach of
this sediment. The geochemical composition of the sediment and its components is one of the
tools used as indicators of past climate variability. However, a calibration is necessary to
improve the connection between geochemical changes and environmental variability, by
comparing the present condition with the recently accumulated sediment chemistry. In
2006 a series of 47 surface samples were recovered, distributed over the Taranto
region. Novel ICP-OES, organic C/N, and δ13C analyses were done and allowed a
geochemical mapping of the area. Comparison of the results with the data obtained
by the project partners will permit us to generate a strong calibration data set for
further studies in this area, and will give us a better understanding of the actual
sediment/climate connection. In addition, the calibration results will be compared to
results obtained from older sediments from the same region. This will permit a first
assessment of eastern Mediterranean/Adriatic sediment response to sub-recent climate
change.
