英文摘要

Planktonic foraminifera and pollen data from core GNS84-C106 (Gulf of Salerno, Tyrrhenian Sea) were analysed through the Modern Analogue Technique, Constrained Cluster Analysis and relative variation biplots. A long period of mild climate, centred around 25 ka BP, is evident in both marine and continental reconstructions. The cooling phase from 17 to 14.7 ka BP, correlated to the H I Heinrich event, is indicated by a sea surface temperature (SST) decrease, which roughly coincides with the cold-arid phase identified by annual and January temperatures. A rapid increase in atmospheric temperatures and precipitation, culminating at 13.8 ka BP, marks the BA cronozone. The corresponding increase in summer and winter SSTs, of 11 and 6.5 degrees C, respectively. occurred over 600 years. The beginning of the YD, centred around 12.5 ka BP, is marked by a decrease in summer and winter SSTs of, respectively, 4.5 and 3.5 degrees C in one century. The atmospheric evidence of the YD is primarily reflected in low January temperatures, reaching -6 degrees C, the lowest values ever experienced in the analysed time interval. The Late Glacial-Holocene transition is clearly recorded in both the continental and marine realms. From 11.5 to 9 ka BP, atmospheric temperatures record a period of substantial stability followed by a drop at 8.9 ka BP, which chronologically fall within the first RCC event (9-8 ka BP) of Mayewski et al. [2004. Holocene climate variability. Quaternary Research 62, 243-255], in correspondence with a phase of relatively high seasonality, indicated by foraminifera. (c) 2008 Elsevier Ltd and INQUA.
