1987年8月至1998年6月期间，96名Argos-Track漂流者横穿日本/东海。利用这些漂流点的位移资料计算了1-3天的平均海流矢量，它描述了15m深度的环流。通过西航道通过朝鲜海峡的漂流者被东韩暖流卷走，通过东航道的漂流者被对马海流卷走。对副极锋以南沿海温暖海域的S−-1海流进行了3天平均40 cm以上的逐个观测。次极锋面上向北的涡旋能量明显减少。涡旋平均流相互作用引起的涡动能转换率显示出明显的耗散和产生区。
During the period of August 1987 to June 1998, 96 Argos-tracked drifters traversed through the Japan/East Sea. The displacement data from these drifters were used to compute 1–3 day average current vectors, which described the circulation at 15 m depth. The drifters that passed through the Korea Strait via the western channel were caught by the East Korean Warm Current, and the drifters that passed through the eastern channel were caught by the Tsushima Current. Individual observations of the 3 day average current over 40 cm s−1 were made in the warm waters south of the subpolar front and along the coasts. There was a distinct decrease of eddy energy northward across the subpolar front. Conversion rates of eddy kinetic energy due to eddy mean flow interaction showed significant regions of both dissipation and production.
