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.

这个项目是对南极环极流（ACC）系统的结构及其与邻近南半球环流域的联系的描述性分析。它将使用在世界海洋环流实验水文测量计划中获得的南大洋剖面，以及历史数据集。分析将遵循五个主题：深海环流的描述，包括通往中纬度的深水和底水通道；横跨ACC的深水交换途径的研究；通过通风和混合，温水沿着ACC进行转化；行政协调会与副热带环流之间的交换；南大洋结构的长期变化这项工作将有助于确定南大洋在建立世界海洋密度结构方面所起的作用。它还将为以后评价南大洋结构的长期变化提供一个基线。
