The data set comprises an xlsx spreadsheet file containing carbon and oxygen stable isotope measurements (δ¹⁸O and δ¹³C), with sample IDs, measured subsurface depths and the interpreted sample age in millions of years ago. The same data are also provided in a csv file with utf-8 character encoding.
δ¹⁸O and δ¹³C were measured using a gas source mass spectrometer at Cardiff University, UK. The measurements were made on the calcium carbonate shells of time-ordered samples of two species of fossil foraminifera: (1) epifaunal benthic (seafloor-living) Cibicidoides spp. and (2) planktonic (lived at the ocean surface) Turborotalia ampliapertura.
Please, cite the study by Coxall et al. (2021) when using this dataset.
The data can be used for identifying the signal of Antarctic glaciation, which can be correlated globally to similar records from other sites, and for reconstructing the local ocean-climate conditions, including sea surface temperature, patterns of sea surface salinity, ocean nutrients, ocean circulation and the strength of ocean stratification.
