Interbasin leaking through Agulhas current filaments

The Agulhas filaments derived from the Agulhas current are responsible for around 15% of the total interbasin salt flux produced by the current. Satellite infrared images of the southeast Atlantic Ocean reveal that the Agulhas filaments are present west of the Agulhas Bank around 56% of the time. Each filament lasts for 3 to 4 weeks and six to seven filaments are formed annually. The excess heat in joules in the filaments varies in the range 0.7-6.9 times 10 to the nineteenth power. The salt flux determined by two different methods gives two different values.
