在Kuchinoshima岛附近观测到了洋流，这是一个利用黑潮海流能量的海流能量转换器开发项目的潜在安装地点。使用声学多普勒海流剖面仪（ADCP）和声学多普勒流速仪（ADV）仪器对一系列频率和垂直位置进行了现场测量。使用这些工具来测量电流，我们使用速度统计来分析洋流特性和度量，包括湍流强度，湍流动能和相干湍流动能，这些都是已知的影响当前涡轮机的行为。然后，频谱分析用于显示洋流波动的各种尺度。根据观测活动持续时间以及ADCP和ADV规范的限制，光谱范围为10-3 Hz至2 Hz或8 Hz。
Ocean currents were observed near Kuchinoshima Island, a potential installation site for a current energy converter development project to harness the energy of the Kuroshio Current. Field measurements were taken for a range of frequencies and vertical positions using both Acoustic Doppler Current Profiler (ADCP) and Acoustic Doppler Velocimeter (ADV) instruments. Using these tools to measure the current, we use velocity statistics to analyze the ocean current characteristics and metrics including turbulence intensity, turbulent kinetic energy, and coherent turbulent kinetic energy which are known to influence the behavior of current turbines. Spectral analysis is then used to show the various scales of fluctuation in the ocean current. The spectral range was on the order of 10-3 Hz to 2 or 8 Hz based on the limitations of the observation campaign duration and the ADCP and ADV specifications.
