摘要：

The isotopic and micropaleontological deglacial records of three deep-sea cores from 44 degrees S to 55 degrees S have been dated by accelerator mass spectrometry. The available records did not allow accurate dating of the initiation of the deglaciation By 13,000 years B.P., sea surface temperatures reached values similar to the present values. A cool oscillation abruptly interrupted this warm phase between 12,000 and 11,000 years B.P. Initiation of this cooling therefore preceded the northern hemisphere Younger Dryas by approximately 1000 years. Complete warming was reached by 10,000 years B.P., more or less synchronous with the northeast Atlantic Ocean.
