Figure 1
The Sergipe and Alagoas Continental Shelf with the 50, 1000 and 2000 m isobaths. The locations of the Japaratuba and Sao Francisco submarine canyons, the river discharge locations, the Sao Francisco, Vaza Barris and Sergipe rivers, and the location of the PCM-9 platform are also represented.
Figure 2
Domain of the numerical model with the local bathymetry. The dashed lines indicate the 3 sections near the Japaratuba canyon, one parallel to the coast and 2 others at the south and north borders of the canyon, in the cross-shore direction.
Figure 3
Wind rose representing the time series of the wind from March 9, 2012 until December 12, 2014, in the oil platform PCM-9. The wind velocity is in m.s-1. The wind rose was created using the original data without any filtering process.
