利用滑翔机对北大西洋中纬度垂直水速的观测，估计了湍流动能的耗散率。该估计基于大涡方法，允许使用大尺度O（1 - 10 m）的湍流能量测量来诊断尺度O（1 mm）上粘性过程的能量耗散率。这里考虑的滑翔机数据是在高分层（1 × 10−4）区域获得的
The rate of dissipation of turbulent kinetic energy is estimated using Seaglider observations of vertical water velocity in the midlatitude North Atlantic. This estimate is based on the large‐eddy method, allowing the use of measurements of turbulent energy at large scales O(1–10 m) to diagnose the rate of energy dissipated through viscous processes at scales O(1 mm). The Seaglider data considered here were obtained in a region of high stratification (1 × 10−4
