Using the CTD data obtained on the R/V Dr.E.L.Holmberg fishery research cruise H-13/94 (November 1994), oceanographic conditions of the coastal area of the Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina) are described. Two physical environments were differentiated: the Río de la Plata estuarine systems and El Rincón coastal regime. In both systems thermal and haline fronts that affect the distribution of reproductive concentrations, nursery and spawning areas of coastal species, are identified. Salinity fields of the AUCFZ, as a function of statistical winds, are synoptically analyzed. In El Rincón, the temporal stability observed on temperature and salinity allowed to describe the mean physical conditions for... |
