The 29 samples were obtained with a multicore between 125 m and 3485 m depth. The analized samples yielded 27 > 150 µm foraminiferans shells/cm3, in which were found 56 species, 21 genus and 11 families. In addition two news species for the studied area and the science: Fissurina susanae n. sp. collected between 42ºS and 44ºS, Oolina margaritae n. sp., found of isolated form to the 38ºS and soon from 42ºS to 44ºS, is fully described.
