ABSTRACT. The hydrographic and hydrodynamics data obtained from a 10 meters deep mooring (0.5 meter above the bottom) located in the Inner Shelf of Paraná, Brazil, from Oct/11/2006 to Dec/10/2006, were analyzed. The oceanographic variability was characterized by maximum values of 54.2 cm.s -1 for current, 2.9 m for height, and 10 s for wave period. The salinity ranged from 32 to 33.7 ups and temperature from 20.7 to 25.3 • C. The wind stress is the main force driving the oceanographic variability, especially during high-energy events, generating waves bigger than 2.5 m, which occur with periods of 7.6 days. The low frequency oscillations dominate the behavior of longshore currents. These currents also answer more effectively to the wind variability. The most important tidal components were the lunar and solar semi-diurnal, M 2 and S 2 , respectively. The temperature and salinity response to the wind effect is faster than circulation pattern response. However, the variability of temperature and salinity associated with the wind energy peaks still needs to be better understood. For this, we need a better understanding of the sources of heat and salt, both local and remote, as well as their variability. A tensão do ventoé a principal forçante que governa a variabilidade dos parâmetros oceanográficos, especialmente nos eventos de alta energia, gerando ondas maiores que 2,5 m, que ocorrem com períodos de 7,6 dias. As oscilações de baixa frequência dominaram o comportamento das correntes longitudinais. Estas correntes também respondem mais efetivamenteà variabilidade do vento. As componentes de maré de maior amplitude foram as componentes lunar e solar semidiurnas M 2 e S 2 , respectivamente. A resposta da temperatura e da salinidade em função da ação do vento ocorre de forma mais imediata que a resposta do padrão de circulação.Entretanto, a variabilidade da temperatura e salinidade associada aos picos de energia do vento ainda precisa ser mais bem compreendida. Para tal,é necessário um melhor conhecimento das fontes de calor e sal, tanto locais quanto remotas, bem como de suas variabilidades.
