Fig. 3. Cases of maximum transport (to north, east, south and west in clockwise order) extracted from the run of the numerical model for the period 2006–2011. The adopted
scale of the wind vectors allows visual comparison of the transports due to the wind (oil moving at 3% of wind speed) and the current.
