| Abstract | The study on climatology comprises the compilation and processing of historic data on the Río de la Plata and its adjacent region. It involved a total of 7,757 oceanographic stations performed between 1911 and 2003. The data were grouped in a warm period (November- March) and a cold one (June-September). The variability in the continental discharge of the Río de la Plata made it necessary to group data as a function of three flow levels: high, mean and low. Previous studies reveal a marked change in the average flow regime of the river basin that stars at the beginning of the 70’s with a cycle of humid characteristics during which 86% of the oceanographic stations were collected. Consequently, the hydrological series used to determine the discharge levels corresponds to the 1972-2001 period. The mean flow was 24,045 m3 s-1 and the high and low discharge values were determined at 28,000 m3 s-1 and 17,370 m3 s-1, respectively. The data were analyzed in ten horizontal levels between the surface and 500 m; the levels were defined at: 0 m, 10 m, 20 m, 30 m, 50 m, 75 m, 100 m, 150 m, 250 m and 500 m. Temperature and salinity horizontal distribution for every level, every warm and cold period and every flow condition was mapped. Over a 0.5º latitude by 0.5º longitude grid, mean value, standard deviation and number of observations were also calculated. |
