  3. Stable oxygen isotope record from Globigerina bulloides and sea surface temperature of sediment core BOFS31/1K (Table 1)

    Chapman, Mark R; Shackleton, Nicholas J; Zhao, Meixun; Eglinton, Geoffrey
    Two techniques for estimating past variations in sea surface temperature (SST) have been used to investigate climatic change in Biogeochemical Oceanic Flux Study (BOFS) core 31K (19°N, 20°W) from the eastern subtropical Atlantic. High-resolution SST records for the last 28 kyr have been produced using planktonic foraminiferal assemblages, based on the Imbrie-Kipp transfer function technique, and the UK' 37 index derived from abundances of C37 alkenones biosynthesized by prymnesiophyte algae. Modern observations suggest that these indices reflect particular hydrographic conditions in the upper ocean: the UK? 37 index corresponds to the temperature at the time of maximum coccolith productivity, typically...
