自1991年2月以来，东北大学物理海洋学小组实施了一项方案，利用安装在小笠原丸号渡轮上的声学多普勒海流剖面仪（ADCP）系统监测日本南部伊豆海岭上的黑潮海流场。这渡轮穿梭在东京和Chichijima之间的小笠原（小笠原）群岛在平常的一年58倍。该ADCP监测被视为东京-小笠原线实验（TOLEX）的一个组成部分。在本文中，我们将简要地介绍我们的ADCP系统和数据处理程序，并将介绍目前的领域的几个方面，使用到1996年1月获得的数据。在此期间，黑潮以34°N和32° 30 'N为平均位置的双峰路径。在黑潮以南海域，观测到了许多尺度为200-400 km的气旋性和反气旋性涡旋，历时2 - 4个月。
Since February 1991, the Physical Oceanography Group, Tohoku University has conducted a program to monitor the oceanic current field across the Kuroshio over the Izu Ridge, south of Japan, using the Acoustic Doppler Current Profiler (ADCP) system installed on the ferry Ogasawara Maru. This ferry shuttles 58 times in a usual year between Tokyo and Chichijima in the Ogasawara (Bonin) Islands. This ADCP monitoring is regarded as one component of the Tokyo-Ogasawara Line Experiment (TOLEX). In this paper, we will briefly describe our ADCP system and data processing procedures, and will present several aspects of the current fields using the data obtained through January 1996. During the period, the Kuroshio took the bimodal paths of 34°N and 32°30'N as mean positions on the ship course. In the sea south of the Kuroshio, many cyclonic and anticyclonic eddies with a scale of 200-400 km in diameter were observed with passing time of two-four months.
