Abstract
The deglacial transition between oxygenisotope Stages 6 and 5e about 127000 yr BP is marked by both oxygen isotopic depletion and estimated seasurface temperature SST increase in two subantarctic Indian Ocean cores The data show synchroneity between warming of foraminiferabased SST estimates and depletion of δ18O but an earlier warming trend on the basis of radiolarian SST estimates These data have been previously interpreted to indicate that the highlatitude Southern Ocean warms prior to significant melting of glacialage ice sheets Comparison of coretop assemblages with surface and subsurface conditions in the Southern Indian Ocean reveals that 1 a threepart foraminiferal zonation reflects the surface hydrographic regime with abrupt faunal transitions at two major fronts the Subtropical Convergence STC and the Antarctic Polar Front APF and 2 a twopart radiolarian zonation coincides with a twopart subsurface hydrographic regime with an abrupt faunal transition corresponding to the southern terminus of subtropical lower water STLW between the STC and the APF It is suggested that shifts of these surface and subsurface regimes are recorded by these foraminiferal and radiolarian assemblages In this interpretation the observed lead of radiolarian SST with respect to δ18O indicates an early response to a southward shift of STLW while the later foraminiferal SST warming indicates a southward shift of the STC Thus the origin of the Southern Hemisphere SST lead may be related to STLW which emanates from the subtropical gyres rather than the polar regions
