On the basis of our observation, we conclude as the following. 1. The greater food supply during the last glacial period, as a consequence of enhanced organic matter flux from surface water, increased the productions of both U. peregrina and C. wuellerstorfi on sea floor during stages 2 and 3. 2. TOC accumulation rates coincide with the differences in \u03b4^\u003c13\u003eC values between U. peregrina and C. wuellerstorfi, reflected that the greater flux of organic matter reaching the sediment, the more ^\u003c13\u003eC depleted CO_2 was released by organic matter decomposing within sediment. We conclude that the down core changes in \u03b4^\u003c13\u003eC difference between U. peregrina and C. wuellerstorfi in cores PN-3 and SST-4 reflect the variations in organic matter fluxes in the Okinawa Trough and in the Ryukyu Fore Arc region for the last 42kyr. 3. The productivity in surface water (as a food supplier) controlled the abundance of organism lived on the sea floor. Decomposition of organic matter also play a role for controlling carbon isotopic composition of not only sea water \u03a3CO_2 in the water column but also the pore water \u03a3CO_2 in the sediment. It is a possibility that this \u03b4^\u003c13\u003eC difference can be utilized as an indicator of the past changes in surface water productivity. These results provide new evidence for paleoceanorgraphic history of the Okinawa Trough and the Ryukyu Fore Arc region.", "subitem_description_type": "Abstract"}]}, "item_9_description_5":
