Compiled Late Pliocene Stable Carbon Isotope Data from Sites in the Atlantic and Pacific Ocean

DOI

Here we compiled stable carbon isotope data from 23 ODP sites in the Atlantic and Pacific, binned by marine isotope stage.Stable carbon isotope data were binned and averaged according to the marine isotope age assignments in the LR04 and the reported ages of the samples from each site. Only Cibicidoides wuellerstorfi values were used, although sometimes measured species was not reported for each sample by the original publication. Please note that some sites have data originating from multiple publications.Calculated values for whole basin δ13C of dissolved inorganic carbon, calculated Δδ13C, and associated uncertainties from the values compiled in MPWP_benthic_isotope_data_compilation. Benthic δ13C data from all sites below 2000 meters water depth were binned by marine isotope stage as defined by the age bounds provided with the LR04 stack. Because of our focus on specific MIS events, sedimentary records with low-resolution age models were excluded. All data are derived from Cibicidoides wuellerstorfi. In datasets composed of isotope measurements of two or more benthic foraminifera species (e.g., ODP 883), only C. wuellerstorfi δ13C data were used. The mean of the binned data across the entire isotope stage from each site was then used to calculate a mean deep Pacific and mean deep Atlantic δ13CDIC estimate for all 11 marine isotope stages in the MPWP, assuming a 1:1 relationship between C. wuellerstorfi δ13C and δ13CDIC. All sites were weighed equally.
