Analyses on various archived data and in situ observations were conducted to clarify behavior of Kuroshio warm-core rings and their role in material transport. Based on satellite sea surface height data, we quantified the distribution and characteristics of various mesoscale eddies in the Kuroshio-Oyashio extension region. Invistigation on vertical profiles near the center of the rings revealed the occurrence of cold and fresh water anomalies in the intermediate layer below the warm water of the rings.

通过对各种资料的分析和现场观测，阐明了黑潮暖心环的行为及其在物质输运中的作用。利用卫星海面高度资料，定量分析了黑潮-俄亥俄延伸区各种中尺度涡旋的分布和特征。对环中心附近垂直剖面的调查显示，在环暖水以下的中间层存在冷水和淡水异常。
