Despite its importance, the deep Pacific during \r\nthe last glacial maximum has received relatively little attention \r\ncompared to the deep Atlantic, in part, because the Pacific poorly \r\npreserves carbonate sediments on the sea floor. Here, we review \r\nthe current state of knowledge of the deep hydrography and circulation \r\nof the glacial Pacific by examining available nutrient-proxy data, \r\nincluding some new d13C and d18O data measured on benthic foraminifera \r\nPlanulina wuellerstorfi from the vicinity of Japan. Available benthic \r\nd13C and d18O and radiocarbon data from the Pacific support the \r\npresence of a deep hydrographic boundary at around 2000m during the \r\nLast Glacial Maximum (Paleoceanography 3 (1988) 343; Paleoceanography \r\n7 (1992) 273; Paleoceanography 13(4) (1998) 323). The deep hydrographic \r\ndivide in the glacial Pacific is similar to what is inferred in the \r\nAtlantic (Quaternary Research 18 (1982) 218; Paleoceanography 3 (1988) \r\n317; Paleoceanography 3 (1988) 343; Annual Reviews of Earth Planetary \r\nSciences 20 (1992) 245; Science 259 (1993) 1148), the Indian (Nature \r\n333 (1988) 651; Paleoceanography 13 (1998) 20), and the Southern Ocean \r\n(Paleoceanography 11 (1996) 191), suggesting that this is a global \r\nphenomenon during the glacial time. The upper water mass has a \r\ndistinctly enriched d13C compared to the deeper water mass, \r\nwhose possible origins are discussed. \r\n","author":null,"citation":"Matsumoto, K., T. Oba, J.
