Resultados de las campañas oceanográficas Mar del Plata I-V. Contribución al trazado de una carta bionómica del área de Mar del Plata. Las asociaciones del sistema litoral entre 12 y 70 m. de profundidad

Under the name of Campañas Oceanográficas Mar del Plata I-V, five oceanographic surveys were done together with the Servicio de Hidrografía Naval, in the area between Faro Querandí and Mar del Sur. (Argentina, Province of Buenos Aires). A total of 82 oceanographic stations were covered and physical-chemical (temperature, oxygen, salinity determinations), sedimental and biological samplings (plankton and bottom organisms) were obtained. Bottom organisms collections were made with a conventional type of dredge 1 meter wide and 46 cm high grame with a net of thin mesh 2,60 m. Macrofauna components were only considered. This data allowed us to attempt a bionomic and litological chart of the studied area.As the sediments seem to have great heterogeneity over the hole studied area, in many cases the bottom fauna collections belonged to defferent associations which made difficult the limitations of areas covered by each one. Anyway we can draw that we are very near the minimun limits.
