Abstract:
Distribution of planktonic foraminiferal tests was studied in four drill cores of Upper Quaternary sediments from the zone of influence of the Canary upwelling and in nine sediment cores from the zone of the Benguela upwelling. Paleotemperatures were reconstructed from these data. It was established that under conditions during stadials, interstadials, and interglacials of Quaternary time, the upwelling existed continuously, intensifying and expanding during colder epochs and weakening and contracting in the warmer intervals. During the last stadial (about 18000 yrs ago), relative cooling of sea waters as compared to central regions of the ocean in the zone of the Canary upwelling was not lower than 9°C (4.5°C higher than at present time), and in the zone of the Benguela upwelling it was not lower than 15°C (8.5°C higher than at present time).
