公海内部系泊传感器turbulence估计，
Open-ocean interior moored sensor turbulence estimates, below a Meddy
摘要：
一个为期一年的时间序列的停泊高分辨率温度T-传感器数据从1455米深度的3900米长的线在约5300米的水在东北大西洋加那利盆地占主导地位的盐度（过）补偿入侵所产生的影响，地中海外流水，这是通常组织为Meddies。在T型传感器上方的Meddy核心通过期间，没有观察到侵入，从而使得可以使用温度记录来量化湍流参数。目前的数据表明，这些海洋内部湍流的估计是从短期（小于0.5小时），而强烈的翻转细胞与垂直尺度<5米。由于湍流惯性子范围被发现延伸到内部波段，翻转主要由与惯性流相关的剪切驱动。动能，电流切变和温度变化峰值在亚惯性频率在Meddy通道，这表明波捕获在温暖的反气旋涡流和/或弱分层层。观测结果进一步表明，内波位移是相干的垂直尺度高达40米的Meddy的存在相比，垂直相干尺度小于25米，在更常见的无Meddy条件下的双扩散入侵。
英文摘要：
A one-year time series of moored high-resolution temperature T-sensor data from 1455 m depth on a 3900 m long line in about 5300 m of water in the NE-Atlantic Canary Basin are dominated by salinity (over-)compensated intrusions arising from the effects of Mediterranean outflow waters, which are commonly organized as Meddies. During the passage of a Meddy-core above the T-sensors, no intrusions were observed, thereby making it possible to use the temperature records to quantify turbulence parameters. The present data show that these ocean-interior turbulence estimates are from short-lived (less than 0.5 h) rather intense overturning cells with vertical scales of <5 m. Because the turbulence inertial subrange is found to extend into the internal wave band, the overturns are predominantly driven by shear associated with inertial currents. Kinetic energy, current shear and temperature variance peak at sub-inertial frequencies during the Meddy passage, suggesting wave trapping in the warm anti-cyclonic eddy and/or weakly stratified layers. The observations further show that internal wave displacements are coherent over vertical scales of up to 40 m during the presence of the Meddy compared with vertical coherence scales of less than 25 m during the more common no-Meddy conditions of double diffusion intrusions.
