(*) Summary:  Paleotemperature reconstructions from Antarctic ice cores rely mainly on δD and δ18O records and the main key factors controlling the observed distribution of δD and δ18O in Antarctic surface snow are mainly related to the condensation temperature of the precipitation and the origin of moisture. Recently, a new deep ice core (1620 m) has been drilled at Talos Dome, a peripheral dome of East Antarctica facing the Ross Sea, in the framework of the TALos Dome Ice CorE (TALDICE) project, involving five European nations and led by Italy. The TALDICE coring site (159 degrees 11'E 72 degrees 49'S; 2315 m; T -41 degrees C; www.taldice.org) is located near the dome summit and is characterised by an annual snow accumulation rate of 80 mm water equivalent. Backtrajectory analyses suggest that Talos Dome is mainly influenced by air masses arriving both from the Pacific (Ross Sea) and Indian Ocean sectors. A preliminary dating suggests for the upper 1560 m an age of about 300,000 years BP. The full TALDICE δ18O record obtained from the bag samples are presented here. This new record will be compared to the ones obtained from the EPICA (both EDC and EDML) ice core as well as with other East Antarctic ice core records.

She was a research technician from 1989 at the Department of Geosciences (University of Trieste) and responsible of the Stable Isotope Geochemistry Laboratory, where she carried out her research activity. She focused mainly on the paleoclimatic interpretation of stable isotope profiles of the Antarctic ice cores.

    Dr. Stenni partecipated at the 1998-99 Antarctic field season at Dome C (EPICA project). In 2003 she was granted the “Felice Ippolito” award by the Accademia Nazionale dei Lincei and Commissione Scientifica Nazionale per l’Antartide.

    Since 2005 she has been Principal Investigator of the Stable-Isotope Working Group of the international project TALDICE. She is also Project Coordinator of a joint research project entitled “Holocene climate variability at high-southern latitudes: an integrated perspective” (HOLOCLIP), in the framework of the European Science Foundation programme PolarCLIMATE. She is the author of 54 papers, of which 70% in peer-reviewed journals.
