POLYCHAETE ASSEMBLAGES IN SW ATLANTIC: RESULTS OF "SHINKAI MARU" IV, V, X AND XI (1978-1979) CRUISES IN PATAGONIA AND BUENOS AIRES

The aim of this paper is to study the polychaete composition from a wide area in the Argentinean shelf, between 36°S and 55°S, by means of samples collected from soft bottoms with Picard dredge, during the "Shinkai Maru" cruises developed in 1978-79. As the study area comprises both the Ma...
