Distribution, relative abundance and diversity of deep-sea species at São Pedro and São Paulo Archipelago, Brazil

The goal of the present study is to investigate vertical distribution, relative abundance and diversity of deep-sea species caught using baited traps at São Pedro and São Paulo Archipelago (SPSPA). The surveys were carried out between January 2012 and June 2014 at depths ranging from 170 to 700 m, c...
