Late Neogene paleoceanography and paleoclimatology of the northeast Indian Ocean (Site 758)

Abstract

Presents records of δ18O and δ13C from planktonic foraminifers, weight percent calcium carbonate, weight percent coarse fraction, magnetic susceptibility, and geomagnetic reversals. Sample spacing of the records ranged from 3 to 10 cm and is equivalent to an average time interval of 2000 to 6000 yr. To circumvent the discontinuity introduced by the gaps, a composite depth section was constructed from multiple cores taken from offset holes at Site 758. The resulting composite depth section extends continuously from 0 to 116 mbsf, from the Holocene to the upper Miocene. -from Authors
