南大洋被认为是全球重要的混合热点之一。在这项研究中，我们进行了同时测量的微尺度湍流和细尺度剪切/应变在澳大利亚南部的南极绕极流（ACC）地区的地转剪切流与背景内波场共存的深海混合现有的细尺度参数化的有效性进行评估。
The Southern Ocean is thought to be one of globally significant mixing hotspots. In this study, we carry out simultaneous measurements of microscale turbulence and finescale shear/strain in the south of Australia to assess the validity of the existing finescale parameterizations of deep ocean mixing in the Antarctic Circumpolar Current (ACC) region where geostrophic shear flows coexist with the background internal wave field.
