Abstract

Five cores from the southern Tyrrhenian and Ionian seas were studied for their tephra and cryptotephra content in the 4.4–2.0 ka time interval. The chronological framework for each core was obtained by accelerator mass spectrometry ¹⁴C dating, the occurrence of distinct marker tephra and stratigraphic correlation with adjacent records. Tephrochronology allowed us to correlate the analyzed deposits with tephra markers associated with Somma-Vesuvius (79 ad), Ischia Island (Cretaio), Mt Etna (FG, FL and FS) and Campi Flegrei (Astroni-Agnano Monte Spina) events. For the first time in the marine setting, a large single glass data set is provided for the Late Holocene Etnean marker beds including the FS tephra (ca. 4.3 ka). Moreover, unknown deposits from Lipari (ca. 2.2–2.0 ka) and Vulcano (3.6–3.3 ka) are also recognized at more distal sites than previously reported. These results contribute to improve the high-resolution tephrostratigraphic framework of the central Mediterranean Sea. They also provide new insights into the chemical composition and dispersal pattern of tephras that can be used as inter-archive tools for regional and ‘local’ stratigraphic correlations and for addressing paleoclimate research.

Funding

This work is dedicated to Urania R/V‐CNR crews for their invaluable contribution to the marine research over the years. C. Corselli is acknowledged for many years of cooperation including Urania 1994 and 1998 cruises and UM42 and AP1.1 core recovery. NWO/NIOZ is acknowledged for shiptime, NIOZ‐technicians and Pelagia crew are thanked for collaboration during the Cortado‐2011 cruise. R. de Gennaro is acknowledged for his assistance during SEM‐EDS acquisition and A. Filippidi for sorting out samples in Utrecht. Biagio Giaccio and an anonymous reviewer are acknowledged for their comments and suggestions that improved the quality of the manuscript. M. Gore, D. Gahan and A. Fletcher helped D.D.I. to think of this ‘question of time’. Financial support for the Marisk12 cruise was provided by the Programma Operativo Nazionale (PON 2007‐2013) funded by the Italian Ministry of University and Research – Project MONICA (grant PON01_01525). This research was financially supported by the Project of Strategic Interest NextData PNR 2011‐2013 ( www.nextdataproject.it ) and by the ERC‐Consolidator TIMED project (REP‐683237).
