“…The millennial-scale climatic changes during MIS-19 can also be recognized in records from the northern Atlantic Ocean (Kleiven et al, 2011) and central Europe (Giaccio et al, 2015;Sánchez Goñi et al, 2016;Regattieri et al, 2019). Figure 5 shows the probable correlations between climate records for the Sulmona Basin in Italy (Giaccio et al, 2015;Regattieri et al, 2019) and the CbCS in Japan (this study).…”

“…Millennial-scale fluctuations in the surface water temperature during MIS-19 can be correlated with European climate changes (Giaccio et al, 2015;Sánchez Goñi et al, 2016;Regattieri et al, 2019), and these are thought to have emerged as a result of atmospheric circulation teleconnection over a wide area. However, there are limited reports of high-resolution analysis in MIS-19, and it is expected that detailed teleconnection mechanisms will be elucidated by comparing analysis results over wide geographic areas.…”

“…Because Marine Isotope Stage (MIS)-19 is an interglacial period with an orbital composition of the Milankovitch cycle similar to that of the current interglacial (MIS-1), it is important to build a detailed understanding of the climatic features of this period for use in making future predictions (Tzedakis et al, 2012;Giaccio et al, 2015;Sánchez Goñi et al, 2016). The Kazusa Group composed of Pleistocene deep-sea deposition is continuously distributed on the Boso Peninsula on the Pacific side of central Japan (e.g., .…”

A high-resolution radiolarian record from 800 to 750 ka was examined from the Chiba composite section (CbCS) of the Kokumoto Formation, including the GSSP (Global Boundary Stratotype Section and Point) for the Lower–Middle Pleistocene boundary, on the Boso Peninsula, Pacific side of central Japan. Total radiolarian abundance was closely related to biological productivity in the surface layer and was observed to increase and repeatedly decrease in the millennial-scale period. Summer SST (sea-surface temperature), which was estimated based on the radiolarian assemblage, was 19°C at the end of MIS-20 (790-793 ka) and fluctuated between 21 and 26°C during MIS-19, with the warm periods tending to be synchronous with high productivity. Recent observations have revealed that productivity increases with a northward shift of the Kuroshio along the Kuroshio-Oyashio boundary zone. Therefore, high productivity in the warmer and stratified conditions during MIS-19 can be interpreted as being closely related to millennial-scale oscillations of the Kuroshio Extension. Such millennial-scale climatic changes were also recognized in southern Europe and are likely related to shifts in climate systems such as AO (Arctic Oscillations) and PDO (Pacific Decadal Oscillations).

“…This decoupling is interpreted as reflective of a weakened control of SST on Iberian atmospheric temperature that, in turn, enhanced transport of atmospheric vapor to the high latitudes, amplifying the production of ice sheets in the early stages of the last glacial cycle (Sánchez Goñi et al, 2013). This process has also been demonstrated for an earlier interglacial (MIS 19;Sánchez Goñi et al, 2016). Other offsets include (1) the gradual change in BG δ 13 C and δ 18 O values across the MIS 8-7 boundary, in contrast to the sharp rise in SST at this time, (2) the anomalously large δ 13 C response to ice-rafting event C24 (111-108 ka), and (3) the persistence of low δ 13 C values as SST decreased from 205-187 ka (Figs.…”

“…The duration of warm intervals is an important consideration when examining the climatic context for hominin evolution and dispersal, as not all interglacial intervals have the same duration. In the southwest Iberian Margin records show that MIS 11c is the longest interglacial spanning approximately 20 kyr followed by MIS 9c (15 kyr), MIS 19 (12 kyr) and finally MIS 7c (10.3 kyr) (Tzedakis et al, 2004b;Roucoux et al, 2006;Tzedakis, 2010;Sánchez Goñi et al, 2016b). Our understanding of climatic drivers and the patterns and timing of ecosystem responses across southern Europe provides a crucial framework for understanding hominin evolution and dispersal.…”

Climatic and environmental changes of the Middle Pleistocene in Europe provide the context for an important phase in the evolution and dispersal of early hominins. Pollen records from terrestrial and marine sediment sequences reveal patterns not usually visible in palaeoenvironmental reconstructions from archaeological sites alone and show that hominin evolution took place against a background of marked environmental change as forests expanded and contracted in concert with global and regional climatic shifts. It is rare to find archaeological material in stratigraphically long and continuous palaeoenvironmental sequences, yet this is what is needed to enable particular phases of hominin evolution to be securely associated with climatic and environmental changes. At the well-known Middle Pleistocene archaeological site of Ceprano in Italy we have been able to produce a pollen record from the sedimentary unit directly below the stratum of the hominin remains. The new pollen data from Ceprano are presented here in full for the first time and provide a detailed picture of interglacial vegetation development during Marine Isotope Stage (MIS) 13. This evidence contributes significantly to our knowledge of the spatial heterogeneity of ecosystem responses to climatic change during this period and helps to further constrain the age of the hominin remains. New sites combining both archaeology and long, continuous high quality palaeoecological records would help clarify the relationship between hominin presence and palaeoclimatic and palaeoenvironmental conditions. In the meantime, better communication between the research communities can also go a long way to improving our understanding of the links between the two.
