Monitoring Brazil's Offshore Currents

摘要

The decision to combine the teamwork of two leading Fugro companies from Brazil and the USA will give Devon Energy do Brasil Ltda optimum services in oceanographic current measurement in deepwater on its offshore Block BM-BAR-03, approximately 120 miles (193 kilometres) off the northern Brazilian coast. "The dynamics of the oceanography in this region can be challenging," explains Rosemary Smith, senior oceanographer. "The North Brazil Current (NBC) and its subsurface component, the North Brazil Undercurrent (NBUC), transport oceanic waters north-westwards along the northern coast of Brazil. Once north of the equator these currents feed a system of zonal counter currents which flow eastwards. Large, anti-cyclonic eddies (NBC rings) can form from the North Brazil Current and propagate northwards.
