Stable foraminifer isotope composition of ODP Site 184-1143, South China Sea

Three holes were cored at the site and combined into a composite (spliced) stratigraphic section that documents complete recovery for the upper 190.85 meters composite depth, the interval of advanced piston coring (Wang, Prell, Blum, et al., 2000, doi:10.2973/odp.proc.ir.184.2000; Wang et al., 2001, doi:10.1007/BF02907085).

The early Pliocene to Holocene sediment sequence provided abundant and well-preserved calcareous microfossils and offered an excellent opportunity to establish foraminiferal stable isotope records. Here, we present benthic and planktonic d18O and d13C records that cover the last 5 m.y. These data sets will provide an important basis for upcoming studies to generate an orbitally tuned oxygen isotope stratigraphy and examine long- and short-term changes in deep and surface water mass signatures (temperature, salinity, and nutrients) with an average sample spacing of ~2.9 k.y. for the benthic and ~2.6 k.y. for the planktonic records.
