The closed and lightless conditions of submarine limestone caves prevent benthos having the potential to mix sediments from settling on the cave floor. Thus the sedimentary record may provide an excellent record of climatic and oceanic variability in a coral reef. In this study, we obtained a 43cm-long sediment core from a submarine cave (about 10m long, 20m deep) of Ie Island off Okinawa Island, and estimated deposition rates from the AMS 14C ages of molluscs. The sediment consists of massive calcareous silt and yields coccolithic, benthic, and planktonic foraminifer. The result of 14C dating indicates that the sediment core covers the past 1, 500yrs and the deposition rate ranges between 2cm/100yrs and 4cm/100yrs.
