VEX: Exploratory Moored Measurements in the Vema Fracture Zone

点击翻译按钮获取中文摘要

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.
