0083268 McCartney/WHOIA moored array will be deployed in the Vema Fracture Zone, a deepchannel between the Guiana Basin and the eastern N. Atlantic through which bottom water from the Antarctic eneters the eastern N. Atlantic.The array of instruments will directly measure the transport and lateral structure of deep and bottom water flowing through the restricted channel and indirectly measure the degree of mixing and its variability. The instruments will stay in the water for roughly one year. The moored array will consist of four newly developed profiling moorings togetherwith two more traditional curren meter moorings. Apart from the sciencequestions that are the focus of the experiment, a by-product will be acomparison of new and traditional approaches to measuring abyssal circulation.

0083268麦卡特尼/WHOIA系泊阵列将部署在维马断裂带，这是圭亚那盆地和大西洋东部之间的一条深水航道，来自南极的底水通过该航道流入北大西洋东部。该仪器阵列将直接测量流经受限航道的深水和底层水的传输和横向结构，并间接测量混合程度及其变化。这些仪器将在水中停留大约一年。系泊阵列将由四个新开发的仿形系泊装置和两个更传统的Curren仪表系泊装置组成。除了作为实验重点的科学方程式外，一个副产品将是测量深海循环的新方法和传统方法的比较。
