 note = {P4 core, which is composed mainly of olive grayish mud with well-developed biogenic structures, was raised from the lower continental slope basin off Shikoku at lat. 32°09'N, log. 133°54'E from a depth of 2700m. Each of samples for ^<14>C dating analysis was taken from 19 horizons throughout the core. And we have done the measurement of ^<14>C age differences between benthic and planktonic foraminifera to determine deep ocean ventilation times, using accelerator mass spectrometry. The results suggest that there are clearly two main mode patterns of paleo-circulation here at about 13,000 y.B.P., which may be called glacial and post glacial type. The formar has a slow mode which are difference ages about 1,000 yr, the latter has complicated puls patterns from 2,000 yr to 1,000 years.},
