本文讨论了在沿着152°E从28°N到41°N的10个系泊处首次部署38个海流-温度计阵列（根据具体位置，持续时间为298-324天）的选定结果。沿沿着152°黑潮延伸区附近的深海涡旋动能比以前在墨西哥湾流高能区附近类似深度观测到的低2至5倍。在28°N，152°E的温跃层动能频率分布与31°N，70°W附近观测到的相似（而不是28°N，70°W），但总能量水平有很大的不同。然而，与相应的强电流区的距离几乎相同。水平雷诺应力的非对角分量的最大尺度纬向分布具有一个特征性的一般形状，即在墨西哥湾流或黑潮延伸区或中纬度急流的南部为负，北部为正，在两个海洋中可获得此类数据的所有水深和数值试验中。
Selected results based on the first deployment (duration was 298–324 days depending on specific location) of an array of 38 current-temperature meters on 10 moorings along 152°E from 28°N to 41°N are discussed. Abyssal eddy kinetic energies along 152°E near the Kuroshio Extension are a factor of 2 to possibly 5 lower than those previously observed at similar depths close to the energetic regions of the Gulf Stream. The thermocline kinetic energy frequency distribution at 28°N, 152°E is similar in shape to that observed at a site near 31°N, 70°W (but not 28°N, 70°W), although the total energy levels are quite different. However, the distance from the corresponding strong current regimes is nearly the same. The largest scale latitudinal distribution of the off-diagonal component of horizontal Reynolds' stress has a characteristic general shape, that is, negative to the south and positive to the north of the Gulf Stream or Kuroshio Extension or mid-latitude jet, at all depths for all longitudes where such data are available in both oceans, and in the numerical experiments examined.
