| contents | The record of planktonic foraminifer abundances at Site 662 during the late Pliocene (~1.7-2.1 Ma) was examined to determine variations in estimated sea-surface temperature (SST). We compared the results to SST estimates from a late Pleistocene record (~1.5-200 ka) from nearby piston core RC24-7. Within the primary orbital band (~20-100 k.y.), the cold-season responses of both equatorial Atlantic records are dominated by the precessional period, and the computed range of variability is quite similar. This is in contrast to the evolution of the dominant climatic response from 41 to 100 k.y. at high northern latitudes between the late Pliocene and the late Pleistocene. 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. |
