Abstract:
Stable isotope records were generated for a late Pliocene-early Pleistocene interval from Ocean Drilling Program (ODP) Site 1123 in the southwest Pacific (41°47 S, 171°30 W; 3290 m water depth). Based on these data, new revisions were made to the shipboard splice and composite section. The isotope records will be used to evaluate the influence of North Atlantic and Southern Ocean deepwater masses on water entering the Pacific in the Deep Western Boundary Current. Three holes were cored at Site 1123, yielding a complete composite section over approximately the last 4.7 m.y. A representative spliced record (“the splice”) was developed aboard ship based on magnetic susceptibility, gamma ray attenuation bulk density, and percent reflectance data from the three adjacent holes (Carter, McCave, Richter, Carter, et al., 1999, doi:10.2973/odp.proc.ir.181.2000). No gaps in the sedimentary record were detected for the multiple-cored section of Site 1123. In addition to the isotope data, postcruise revisions to the splice and composite section based on stable isotope data are described here.

Comment:
Depth, sediment is the depth of each Hole (mbsf). Interspecies corrections for oxygen isotope values followed Shackleton (1974), adding 0.64 to delta18O values from Cibicides sp. An offset of -0.9 was added to delta13C values measured from Uvigerina sp. (Duplessy et al., 1984, doi:10.1016/0033-5894(84)90099-1); 0.35 was added to the delta18O value for the single Nuttalides umbonifera analyzed (Shackleton and Hall, 1984, doi:10.2973/dsdp.proc.81.116.1984). The average species offsets between C. wuellerstorfi and Uvigerina sp. that were calculated for duplicates within the Site 1123 data set are in statistical agreement with these offsets
