Radioisotopes (^<230>Th, ^<232>Th, ^<238>U, ^<234>U, ^<210>Pb, ^<231>Pa and ^<14>C), and CaCO_3 were measured to understand the variation of paleo flux and sedimentation rate during the last glacial period. ^<14>C age data show that the ages at the top and 200cm depth are 11,400 yr BP and 40000 yr BP, respectively. The sediment at 20cm depth may have been of terrestrial origin. The ^<231>Pa data suggest that the particulate flux at the station has been high compared to average open ocean for last 40000 years.}, pages = {167--175}, title = {放射性核種による北西部北太平洋の堆積環境の変遷について}, volume = {10}, year = {1999} }
