Abstract
(English)
We present a high-resolution record of marine sediments from the eastern margin of the Tyrrhenian sea for the late Quaternary-Holocene which combines geochemical, physical and biological information in a multi-proxy generated time framework (calcareous plankton ecobiostratigraphy, oxygen isotope stratigraphy, 210Pb and 137Cs, AMS 14C and tephrostratigraphy). Evidence of the most relevant climatic events reported for the last ~15,000 years and direct correlation with solar activity estimated from NGRIP and GISP 14C records offer a first-order knowledge of climate-ocean dynamics and trophic responses of the Mediterranean sea during the late Quaternary and Holocene. Mass balance calculations applied to the collected 18OG.ruber record, constrained in terms of sea surface temperatures by data reported by Di Donato et al. (2010) from a coeval close sedimentary record, provided new insights on secular changes in hydrological regimes and evaporation/precipitation budgetof the Tyrrhenian sea during the late Quaternary and during key intervals of the Holocene.
