However, this does not disprove that short changes in intensity or direction of the Kuroshio ever occurred at certain short cooling events. The 10Be minimum during the Younger Dryas event may indicate that the Kuroshio had been once greatly weakened or even terminated in the Okinawa Trough area which could be related to the response of the Pacific Ocean to the Younger Dryas. The 10Be and 9Be in surface sediment show totally different distribution patterns. The 10Be distribution is dominated by the input from Kuroshio and its branch, the Yellow Sea Current, whereas 9Be is mainly influenced by terrestrial input of suspended materials from the Yellow River discharge and deposited in the fine-grain size sediment zone southwest of the island of Jeju. Both 10Be and 9Be distribution patterns are different from anthropogenic pollutants such as heavy metal Pb which is dominantly distributed closely to the coastal areas.
