1999年夏季，在连接鄂霍次克海和北太平洋的两个主要海峡之一的克鲁增什特尔纳海峡进行了声学多普勒流速剖面仪的流量测量。通过11次连续的投射获得了2个站点的近一天的时间序列，每次投射每隔2.5小时开始。用最小二乘拟合法估计各分潮分量。该流由两层交换流和量级相当的潮汐组成。从鄂霍次克海到北太平洋的上层体积输送估计为1.6 Sv（1 Sv = 106 m³/s），而下层的相反方向为1.3 Sv。水文和氧气数据支持剩余交换流的存在。
Flow measurements at Kruzenshterna Strait, one of the two major gaps connecting the Sea of Okhotsk and the North Pacific were performed with a Lowered Acoustic Doppler Current Profiler in summer of 1999. Nearly one‐day time series at 2 stations were obtained by eleven consecutive casts, each being started every 2 and a half hours. The tidal components are estimated by least square fittings. The flow consists of a two layer exchange flow and the tide of the comparable magnitude. A volume transport of the upper layer is estimated to be 1.6 Sv (1 Sv = 106 m³/s) from the Okhotsk Sea to the North Pacific, while that of the lower layer is 1.3 Sv in the opposite direction. Hydrographic and oxygen data support the existence of the residual exchange flow.
