Abstract: In order to examine the cause of underwater Jomon sites observed in Goto Islands, sea-level change during the past 8,000 yr BP at Fukue Island has been evaluated based on diatom assemblage and pyrite-sulfer analyses for boring cores and 14C dating for mollusks. The data indicate that the mean sea-level at about 5,000 yr BP was -1.9m and then gradually rose to the present level. Thus the sea-level obtained in this study and underwater sites are indicative of crustal subsidence caused by hydroisostasy, sea-water loading of Holocene transgression.
