Supplemental Information | STUDY NOTES: Glacial and Holocene benthic Planulina (Cibicidoides) wuellerstorfi foraminiferal stable isotope data (d18O and d13C) from 8 sediment cores raised from the vicinity of Japan, between latitudes 28°N and 36°N and from a range in water depth from 740 to 3320 m. Isotopes values are reported per mil vs VPDB. ABSTRACT SUPPLIED BY ORIGINATOR: The deepwater of the Pacific Ocean is a key component of the global climate system on the time scale of late-Pleistocene glaciation and deglaciation. Despite its importance, the deep Pacific during the last glacial maximum has received relatively little attention compared to the deep Atlantic, in part, because the Pacific poorly preserves carbonate sediments on the sea floor. Here, we review the current state of knowledge of the deep hydrography and circulation of the glacial Pacific by examining available nutrient-proxy data, including some new d13C and d18O data measured on benthic foraminifera Planulina wuellerstorfi from the vicinity of Japan. Available benthic d13C and d18O and radiocarbon data from the Pacific support the presence of a deep hydrographic boundary at around 2000m during the Last Glacial Maximum (Paleoceanography 3 (1988) 343; Paleoceanography 7 (1992) 273; Paleoceanography 13(4) (1998) 323). The deep hydrographic divide in the glacial Pacific is similar to what is inferred in the Atlantic (Quaternary Research 18 (1982) 218; Paleoceanography 3 (1988) 317; Paleoceanography 3 (1988) 343; Annual Reviews of Earth Planetary Sciences 20 (1992) 245; Science 259 (1993) 1148), the Indian (Nature 333 (1988) 651; Paleoceanography 13 (1998) 20), and the Southern Ocean (Paleoceanography 11 (1996) 191), suggesting that this is a global phenomenon during the glacial time. The upper water mass has a distinctly enriched d13C compared to the deeper water mass, whose possible origins are discussed. |
