High-resolution foraminifer stable isotope record of MIS 19 at Montalbano Jonico, southern Italy: A window into Mediterranean climatic variability during a low-eccentricity interglacial

Formal ratification of the Global Boundary Stratotype Section and Point (GSSP) for the Chibanian Stage and Middle Pleistocene Subseries of the Quaternary System: the Chiba Section, Japan†

“…The duration of full interglacial conditions within MIS 19 is estimated to be ca. 10 ka (785.0 to 775.1 ± 5 ka) (Suganuma et al, 2018), which is statistically indistinguishable with the MIS 19c duration recorded in the lacustrine Sulmona section (10.8 ka; Giaccio et al, 2015) and Montalbano Jonico section (MJS) (11.5 ± 3.4 ka; Nomade et al, 2019) from Italy, and from North Atlantic records (e.g., 10.5-12.5 ka; Tzedakis et al, 2012). Significantly, full interglacial conditions are followed by a brief cooling event at 774 ka O) stratigraphy from the Chiba composite section (CbCS) modified from Haneda et al (2020b).…”

“…This model gives 44 cm/kyr as a minimum sedimentation rate during the interval of highest global sea level (Elderfield et al, 2012). MIS 19 substages (MIS 19c,19b,and 19a) are assigned using the climatic variables proposed by Nomade et al (2019): MIS 19c corresponds to the onset and climatically stable part (main part) of Stage 19,MIS 19b to the first climatic cooling, and MIS 19a to the most unstable part of Stage 19. Astronomical ages for each of the MIS and substage boundaries are estimated to be 787.5 ka , 770.1 ka , and 756.9 ka based on the full δ 1 8 O benthic dataset of the Chiba composite section (Haneda et al, 2020b).…”

Multiproxy sedimentological and geochemical analyses across the Lower–Middle Pleistocene boundary: chemostratigraphy and paleoenvironment of the Chiba composite section, central Japan

“…The M-B boundary is located~110 cm above the Byk-E tephra layer in the Chiba section (Okada et al 2017) and lies in an interval with a sedimentation rate of 89 cm/kyr (Suganuma et al 2018). MIS substages (MIS 19c,19b,and 19a) have also been assigned based on the climatic variables proposed by Nomade et al (2019); MIS 19c corresponds to the climatically stable part of Stage 19,MIS 19b to the first climatic cooling stage, and MIS 19a to the most unstable Fig. 1 Oceanographic circulation in summer around Japan.…”
