Major elements were studied for reconstruction of sediment provenance and paleoenvironment over the last 24 ka B.P. with the samples collected from Core PC-1 in the northern Okinawa Trough. In addition to major elements, grain size of 402 samples and planktonic foraminifer δ¹⁸O of 344 samples have been analyzed that leads to an average resolution at centennial scale. The study offers a new high resolution material for reconstructing the history and main control factors of the sediment input in the northern Okinawa Trough over the last 24 ka. In particular, the contribution of nearby terrestrial materials show an obvious change trend and can be well correlated with the sea level fluctuation and the evolution of the Tsushima Warm Current.It seems that paleoclimate renders no significant impact on the change in terrigenous sediment provenance.
