Ecohydrodynamical study of the Liguro-Provençal Front (Corsica) I. Hydrological data

Hydrological measurements (temperature, conductivity, salinity) have been realized in 1982 and 1984 along the Calvi - Nice axis from the Corsican coast to 30 miles offshore. The data have shown a thermohaline front separating low saline coastal waters of atlantic origin from high saline offshore waters of deeper origin. A succession of divergences and convergences is associated to that discontinuity. During spring, the front is emphasized and the water upwellings reach the surface. During summer, the upwellings are limited by the vertical stratification but an isopycnal inclination is always observed from the front to the coast.
