最近开发的一种基于安装在电导率-温度-深度设备上的快速响应热敏电阻的微结构测量技术被用于8次航行，获得438个剖面。因此，整个北太平洋海底的湍流耗散率的空间分布进行了说明，并发现是相关的结果，利用潮汐引起的能量耗散和密度分层。然后将观测到的湍流分布与基于具有潮汐强迫的高分辨率数值海洋模式的耗散率进行比较，并描述了观测和模拟分布之间的差异和相似性。湍流强度的观测结果表明，数值模式是高估，可以通过比较它与观测到的流域尺度耗散率进行改进。这种新方法使湍流观测更容易和更广泛，大大提高了我们对海洋混合的认识。
A recently developed technique for microstructure measurement based on a fast-response thermistor mounted on a conductivity-temperature-depth equipment was used on eight cruises to obtain 438 profiles. Thus, the spatial distribution of turbulent dissipation rates across the North Pacific sea floor was illustrated, and was found out to be related to results obtained using tide-induced energy dissipation and density stratification. The observed turbulence distribution was then compared with the dissipation rate based on a high-resolution numerical ocean model with tidal forcing, and discrepancies and similarities between the observed and modelled distributions were described. The turbulence intensity from observation showed that the numerical model was overestimated, and could be refined by comparing it with the observed basin-scale dissipation rate. This new method makes turbulence observations much easier and wider, significantly improving our knowledge regarding ocean mixing.
