“…Teleconnection phenomena between the Mediterranean and the Greenland/North Atlantic region are documented for the late Quaternary (e.g. Rohling et al, 1998;Cacho et al, 1999;Sbaffi et al, 2001;Rohling et al, 2002b;Sprovieri et al, 2003;Martrat et al, 2004;Pérez-Folgado et al, 2004;Sprovieri et al, 2006;Incarbona et al, 2008a). This connection has been explained by variations in North Atlantic Deep Water formation rate, as modelling experiments suggest that this mechanism is able to cause coherent temperature changes in the two regions (e.g.…”

“…The paleoclimatic curve presented here is the algebraic sum of warm-water species percentages (G. ruber, Hastigerina siphonifera, G. sacculifer, Globoturborotalita rubescens and Globoturborotalita tenella) expressed as positive values and cold-water species percentages (Neogloboquadrina pachyderma, G. bulloides, Turborotalita quinqueloba, Globorotalia scitula and Globigerinita glutinata) expressed as negative values (Corselli et al, 2002;Sprovieri et al, 2006;Incarbona et al, 2010). In fact, among others, G. ruber ecological preference for warm and oligotrophic surface waters has been established in numerous oceanographic settings (Hemleben et al, 1989;Pujol and Vergnaud-Grazzini, 1995;Žarić et al, 2005) and paleoceanographic reconstructions (Sprovieri et al, 2003(Sprovieri et al, , 2006(Sprovieri et al, , 2012; T. quinqueloba thrives in cold and nutrient-rich surface waters (Hemleben et al, 1989;Pujol and Vergnaud-Grazzini, 1995;Žarić et al, 2005); N. pachyderma dx lives in cold waters of middle-high latitude and is a proxy for deep chlorophyll maximum levels (e.g. Rohling and Gieskes, 1989).…”

The Middle Pleistocene Transition (1.2-0.7 Ma) is the most recent re-organization of the global climate system which includes variations in the frequency and amplitude of glacial/interglacial cycles, increased ice sheet volume, sea surface temperature cooling and a significant drop in the CO 2 atmospheric levels. Here we present high-resolution planktonic foraminifera data (mean sampling resolution of about 780 years) from core LC10 recovered in the Ionian Sea (eastern Mediterranean), between 1.2 and 0.9 Ma. Selected taxa, among them G. ruber, T. quinqueloba and G. bulloides, show significant periodicities that can be associated to orbital cycles, mainly precession and obliquity. The planktonic foraminifera based paleoclimatic curve exhibits a cooling linear trend that can be associated to similar phenomena observed in the North Atlantic. On the other hand, we refer to the influence of the North African Monsoon the occurrence of two peaks of the low-salinity tolerant species G. quadrilobatus that fall in coincidence of sapropel layers. Finally, we discuss the distribution pattern of N. pachyderma sinistral coiling, with peaks up to about 20% between MIS 30 and 28, and compare it to middle-late Quaternary records of the Sicily Channel and western Mediterranean.

“…This area is nowadays very sensitive to modifications in the Mediterranean thermohaline circulation [11,12] and, for many reasons, suitable for paleoceanographic research: the very high-sedimentation rate of Site 963, specifically between 18.0 and 50.0 cm/kyr over the last 130 kyr [13][14][15][16]; the flow of Levantine Intermediate Water (LIW) at the sea floor, a key water mass for understanding Mediterranean oceanographic dynamics; the middle-latitude location, suitable to provide information on the interaction among different climatic systems.…”

Abstract:The geographical location, the shape and the circulation pattern makes the Mediterranean Sea an ideal laboratory to study the interplay between different climatic systems, abrupt climate changes and the response of marine ecosystems. The Ocean Drilling Program Site 963 was drilled in the Northwestern part of the Sicily Channel, the sill that divides the western from the eastern Mediterranean Sea. Numerous papers have been published on Site 963 sediments in the last decade, investigating Mediterranean paleoceanographic themes. Here we offer a synthetic framework of these investigations carried out by sub-centennial resolution. We present the whole sequence of suborbital climatic oscillations over the last 130 kyr, that is since the last interglacial period, and we claim that teleconnection with Greenland and North Atlantic regions is the most likely phenomenon to explain our results. Furthermore we show the high sensitivity of marine planktonic (planktonic foraminifera and coccolithophores) ecosystems to Stadial/Interstadial fluctuations. We conclude that a three-steps scenario may describe productivity variations during each high-frequency oscillation, from Interstadial 24 to the last deglaciation (from 110 to 15 kiloyears ago): surface oligotrophy and a deep nutricline in the lower part of Interstadials; increased productivity, through a deep chlorophyll maximum and winter/spring coccolithophore blooms, during the upper part of Interstadials; a shallow nutricline during Stadials and possibly reduced productivity levels with respect to the upper Interstadial phase. Results from Site 963 investigations provide key information for very highresolution paleoceanographic research in the Mediterranean Sea.

Whereas millennial to submillennial climate variability has been identified during the current interglacial period, past interglacial variability features remain poorly explored because of lacking data at sufficient temporal resolutions. Here we present new deuterium data from the EPICA Dome C ice core, documenting at decadal resolution temperature changes occurring over the East Antarctic plateau during the warmer-than-today last interglacial. Expanding previous evidence of instabilities during the last interglacial, multicentennial subevents are identified and labeled for the first time in a past interglacial context. A variance analysis further reveals two major climatic features. First, an increase in variability is detected prior to the glacial inception, as already observed at the end of Marine Isotopic Stage 11 in the same core. Second, the overall variance level is systematically higher during the last interglacial than during the current one, suggesting that a warmer East Antarctic climate may also be more variable.
