0118410McCartney/WHOI & Donohue/URIThis project is a descriptive analysis of the structure of the Antarctic Circumpolar Current (ACC) system and its connection to adjacent southern hemisphere circulation domains. It will use the Southern Ocean sections obtained during the Hydrographic Program of the World Ocean Circulation Experiment, as well as historical data sets. The analysis will follow five themes: a description of the abyssal circulation, including deep and bottom water pathways to mid-latitudes; a study of the pathways of exchange of deep water across the ACC; the transformation, by ventilation and mixing, of warm water along the ACC; exchange between the ACC and subtropical gyres; secular changes in the structure of the Southern Ocean. This work will help determine the role played by the Southern Ocean in establishing the density structure of the world's ocean. It will also provide a baseline for later evaluations of long-term change in the structure of the Southern Ocean.

0118410 McCartney/Whoi＆Donohue/ureithis项目是对南极圆极电流（ACC）系统结构及其与邻近南半球循环域的连接的描述性分析。 它将使用在世界海洋循环实验的水文计划以及历史数据集中获得的南方海洋部分。该分析将遵循五个主题：对深渊循环的描述，包括通往中纬度的深水和底部水路；一项研究在ACC上交换深水的途径；通过通风和混合沿ACC进行通风和混合的转化； ACC和亚热带回旋之间的交换；南洋结构的世俗变化。 这项工作将有助于确定南洋在建立世界海洋密度结构中所扮演的角色。 它还将为以后评估南大洋结构的长期变化提供基准。
