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.

冰期时冲绳海槽北部10Be的沉积通量远远高于太平洋大洋海区，充分反映了黑潮的传送带作用和边缘海的聚焦沉积作用，并表明末次冰期时在千年尺度上黑潮仍流经冲绳海槽，且强度并未减弱。10Be的通量在新仙女木时降到整个岩芯所跨时期的最低点，甚至低于10Be的现代大气平均生产率，因此推测在新仙女木事件时，黑潮的变动特别大，有可能改向或断流。
