The article presents a dataset comprehending 1,094 Brazil Current inner fronts mapped from January-2011 to September-2015, using Sea Surface Temperature (SST) and Chlorophyll-a (Cl-a) orbital images, over the Espírito Santo, Campos, Santos and northern Pelotas Basins, SW Atlantic. 319 fronts were mapped in Summer, 264 in Autumn, 308 in Winter and 203 in Spring. The resulting frontal density fields indicate higher frontal spatial stability over three areas under the influence of semi-permanent eddies: (i) São Tomé Eddy, (ii) Cabo Frio Eddy and (iii) Shelf break eddy near São Sebastião Island. The Vitória Eddy signal was observed at the Winter frontal density field. The frontal occurrence distribution profiles, extracted from four radial transects, show different variability and position patterns over the study area. That present extensive Brazil Current fronts dataset can be used to feed descriptive statistical models or as a training dataset for a machine learning algorithm in order to improve the knowledge about the Brazil Current characteristics.
