Paleoceanographic proxy data sets from the Eocene-Oligocene boundary interval of ODP Site 1218, eastern Equatorial Pacific

Helen Coxall

Paleoceanographic proxy records from Ocean Drilling Program Site 1218 in the eastern equatorial Pacific (EEP): (1) stable isotope (δ¹⁸O and δ¹³C) records measured on epifaunal benthic foraminifera (Cibicidoides spp.); (2) δ¹⁸O and δ¹³C records measured on Oridorsalis umbonatus, a shallow infaunal species; (3) bulk sediment accumulation rate (MAR) and carbonate accumulation rate (CaCO3AR); and 4) a record of benthic foraminifera accumulation rate (BFAR). Sample ages are between 30.9 and 35.3 Ma.

Comments

The Site 1218 Eocene-Oligocene benthic foraminifera stable isotope data sets represent an expansion of the data set presented by Coxall et al. (2005). The Site 1218 Eocene-Oligocene benthic foraminifera accumulation rate (BFAR) data set was originally presented in Coxall and Wilson (2011). The BFAR data were corrected (standardized to bulk weight of sample) in a subsequent paper Moore et al. (2014).
