“…There is also an evidence of presence of CW mainly in the region of the Albardão during the two campaigns. Boltovskoy et al (1980), describe Bolivina striatula, Buliminella elegantissima, Elphidium excavatum, E. gunteri, and Elphidium spp. as being marine euryhaline, tolerant to less saline waters of the Patos Lagoon and Plata River, and Eichler et al (2007) have found Buliminella elegantissima, Elphidium excavatum, and Elphidium poeyanum in polyhaline water (18-30 psu) where sand-silt sediments of Bertioga estuarine channel are enriched with organic carbon and sulfur.…”

“…A pioneering study carried through by Boltovskoy et al (1980) in that region made possible the identification of the large-scale Foraminiferal distribution in the South Atlantic, associating it to the great systems of oceanic circulation, Brazil Current (BC) and Malvinas Current (MC) (Figure 1). Our study, however, focuses on the coastal environments influenced mainly by freshwater runoff and coastal water masses interactions that will be described below.…”

More than 30% of Buccella peruviana (D'Orbigny), Globocassidulina crassa porrecta (Earland & HeronAllen), Cibicides mackannai (Galloway & Wissler) and C. refulgens (Montfort) indicate the presence of cold Sub Antarctic Shelf Water in winter, from 33.5 to 38.3° S, deeper than 100 m, in the southern part of the study area. In summer, the abundance of this association decreases to less than 15% around 37.5-38.9° S where two species (Globocassidulina subglobosa (Brady), Uvigerina peregrina (Cushman) take over. G. subglobosa, U. peregrina, and Hanzawaia boueana (D'Orbigny) are found at 27-33° S in both seasons in less than 55 m deep in the northern part, and are linked with warm Subtropical Shelf Water and Tropical Water.
