Comparison of late Pliocene and late Pleistocene sea-surface temperatures of the equatorial Atlantic divergence

Abstract

The record of planktonic foraminifer abundances at Site 662 during the late Pliocene (~1.7-2.1Ma) was examined to determine variations in estimated sea-surface temperature (SST). We compared the results to SST estimates from a late Pleistocene record (~1.5-200ka) from nearby piston core RC24-7. The orbital-band SST response in this region of greatest divergence in the equatorial Atlantic has not changed appreciably between the late Pliocene and the late Pleistocene. -from Authors
