Abstract
Theδ 18O andδ 13C compositions of glacial- to Holocene-aged benthic foraminifera in a core collected from the eastern Arabian sea (water depth 1230 m) were determined to investigate glacial—interglacial variations in the intermediate depth water chemistry of the North Indian Ocean. In addition, we determined theδ 13C composition of Holocene benthic foraminifera from seven cores for which theδ 18O andδ 13C of benthic foraminifera from last glacial maximum (LGM) were reported by Kallel et al. (1988). Theδ 13CDIC in the intermediate waters was generally depleted by 0.3–0.4‰ during the last glacial maximum compared to Holocene.
