North Brazil Current Ring Experiment Synthesis

0136477/Fratantoni这个项目涉及分析和综合最近完成的巴西北部洋流环实验的几种类型的数据。这项实验的初步结果表明，这些大的海洋涡旋可能在热带大西洋携带了大量的上层海洋经向物质输送。可用于该综合的数据包括RAFOS浮标和水面漂流轨迹、多个巡航的水文数据、来自海流计系泊和反向回声测深仪的数据。预计最受关注的将是浮标和漂流数据，以及水文图。分析有几个目的，包括：描述分离后NBC环的物理结构；确定环向西北移动时的平移、混合和衰变速率；确定当NBC环遇到安的列斯群岛时造成NBC环变形和破坏的过程；以及查明南大西洋水在环核中的命运。

0136477/FratantoniThis project involves the analysis and synthesis of several types of data from the recently completed North Brazil Current (NBC) Ring Experiment. Preliminary results from this experiment suggest that these large ocean eddies may carry a significant amount of upper ocean meridional mass transport in the tropical Atlantic Ocean. Data available for this synthesis include RAFOS float and surface drifter trajectories, hydrography from multiple cruises, data from current meter moorings and inverted echo sounders. It is expected that most attention will be given to the float and drifter data, together with the hydrography. The analysis has several aims including: describing the physical structure of NBC rings after separation; determining rates of translation, mixing and decay as rings move north-west; determining the processes responsible for deformation and destruction of NBC rings as they encounter the Antilles; and to identify the fate of the S. Atlantic water in ring cores.
