Abstract

The following differences can be recognized world-widely between the last glacial and postglacial periods. In the last glacial period, 1) δ<sup>13</sup>C value of benthic foraminiferal test was 0.5‰ smaller, 2) cadmium and calcium ratio of benthic foraminiferal test was about 20% higher, 3) atmospheric CO<sub>2</sub> content was about two-third, and 4) large amount of dust had accumulated in polar region. And also 5) calcium carbonate preservation spike had occurred during the transitional period from the last glacial to postglacial. The oceanic environmental change which can systematically explain these differences is discussed in detail.
