| Zusammenfassung |
| Within this study, embedded into the ESF-MOCCHA Project (Multidisciplinary study of
continental/ocean climate dynamics using high-resolution records from the eastern
Mediterranean), we combine available high-resolution downcore Sea Surface Temperature
reconstructions for the last 700 years based on the alkenone derived U37K-² Index and oxygen
isotopic composition of planktic foraminifera on the Gallipoli shelf (Gulf of Taranto, S Italy).
A calibration of these two proxies based on surface sediment samples indicates
that alkenones dominantly reflect spring temperatures whereas foraminifera are
representative of summer temperatures. With the combination of these proxies we
will discuss changes in hydrography and seasonal patterns of temperature in this
area.
