A multi-institution field experiment is designed to study the spatial and temporal evolution of North Brazil Current (NBC) retroflection and the separation of rings from the retroflection. The physical structure of the rings after separation from the NBC, including their sizes, vertical structure, horizontal swirl velocities and the volume of South Atlantic water they trap and transport will be determine. The observations will combine complementary techniques: an inverted echo sounder array within satellite altimeter tracklines, current, temperature and salinity mooring, Lagrangian surface drifters and subsurface floats and shipboard surveys.

设计了一个多机构的现场实验，研究了北巴西流（NBC）的空间和时间的演变和环的分离。将确定从NBC分离后的环的物理结构，包括它们的大小、垂直结构、水平漩涡速度以及它们捕获和运输的南大西洋水的体积。观测将结合联合收割机的补充技术：卫星测高仪轨迹线内的倒置回声测深仪阵列、海流、温度和盐度系泊、拉格朗日表面漂移器和地下浮子以及船上测量。
