lasts a good part of the year, from spring to autumn (\citealp{Merino_1997}), which had demonstrated the importance of upwelling waters to the productivity of the bank, as Nitrate distributions of the upwelled water layer fertilize the shelf (\citealp*{FURNAS1987161}, \citealp{Merino_1997}). Despite there is no Nitrate data on the western side we believe it enhances its productivity, although more hydrographic evidence is needed to enlarge our understanding of this phenomenon on this side of the shelf and the role it may play in the seasonal and interannual variation of the fishing resources.
