Abstract. RECENT BENTHIC FORAMINIFERA OF THE ARGENTINIAN CONTINENTAL SHELF (39°- 43° S AND 58°- 65°W)  ANALYSED WITH STATISTICAL METHODS FOR COMPOSITIONAL DATA. The analysis of recent benthicforaminifera from the continental shelf and San Matías Gulf is presented. Quantitative analysis was per-formed using methods from compositional data analysis theory. Principal Components Analysis, Clusteranalysis and Geographic Information System (GIS) were used to infer a) six groups of species that respondto oceanographic conditions, four of which were related to coastal waters and the others could be influ-enced by the Malvinas current system; b) the relationship between 13 species and the water temperature,bottom sediments, and energetic conditions of the area c) a correlation between Cibicides dispars/Buliminapatagonica and Cibicides mckannai/Bulimina patagonica and water temperature.
