North Brazil Current Rings Experiment : surface drifter data report, November 1998-June 2000 (original) (raw)

The North Brazil Current Rings Experiment focused on understanding the formation and transport mechanisms of North Brazil Current (NBC) rings, which are pivotal in upper-ocean water transport from the South Atlantic to the North Atlantic. Over three survey cruises from November 1998 to June 2000, a total of 45 surface drifters were deployed to gather data on temperature, velocity characteristics, and the dynamics of NBC rings. The goals included quantifying rings' transport efficiency and characterizing their evolution as they translated northwest towards the Caribbean Sea, contributing to a better understanding of the Atlantic meridional overturning circulation.
