洋流中的动能或海洋流体动力学（MHK）能是一种可再生能源，可以帮助满足全球能源需求。一项基于海洋环流模型的普查显示，亚热带表面西边界流（WBCs）是唯一一个速度足够快的近岸大规模海流，可以驱动未来使用的大型发电海洋涡轮机。我们回顾了几个白细胞的背景下，动能提取。在北卡罗来纳州外的墨西哥湾流中，在水面以下75米处的功率密度有时达到每平方米几千瓦，并且年平均功率约为500- 1，000 W m-2。显著的波动周期为3-20天（墨西哥湾流蜿蜒）和数周至数月（墨西哥湾流路径变化）。年平均功率的年际变化是由于WBC运动的逐年变化造成的。目前还没有大型涡轮机，在WBC中建立MHK设施的道路将遇到与海上风电开发相关的许多方面相似的挑战。
The kinetic energy in ocean currents, or marine hydrokinetic (MHK) energy, is a renewable energy resource that can help meet global energy requirements. An ocean circulation model-based census shows that subtropical surface western boundary currents (WBCs) are the only nearshore, large-scale currents swift enough to drive large electricity-generating ocean turbines envisioned for future use. We review several WBCs in the context of kinetic energy extraction. The power density in the Gulf Stream off North Carolina at times reaches several thousand watts per square meter at 75 m below the surface, and the annual average power is approximately 500-1,000 W m-2. Significant fluctuations occur with periods of 3-20 days (Gulf Stream meanders) and weeks to months (Gulf Stream path shifts). Interannual variations in annual average power occur because of year-to-year changes in these WBC motions. No large-scale turbines presently exist, and the road to establishing MHK facilities in WBCs will encounter challenges that are similar in many aspects to those associated with the development of offshore wind power.
