Sea surface temperature record of DSDP site 81-552A

DOI

Alkenone sea surface temperature (SST) data for DSDP Hole 81-552A, located on the Rockall Plateau: depth, age, sample mass and alkenone-based SST estimates. The sample mass represents the total amount of di- and tri-unsaturated alkenones (in nanograms) injected into the gas chromatography (GC) column during analysis. UK'37 SST estimates are calculated using the global core-top calibration of Conte et al. (2006) and the Bayesian calibration (BAYSPLINE) of Tierney and Tingley (2018). The UK'37 SSTs (calculated using the Conte et al. (2006) calibration) have subsequently been corrected for warming and cooling bias introduced during GC analysis, following the methods outlined in this study. The age model for DSDP Hole 81-552A is based on the magnetostratigraphy of Lazarus et al. (1995) calibrated to the astronomically-tuned Neogene time scale of Hilgen et al. (2012). This dataset further constrains the magnitude and duration of alkenone-derived sea surface warming in the NE Atlantic during the mid-Piacenzian Warm Period.
